1) What are the data types available in typescript and explain in detail Explain JavaScript, TypeScript and its advantages (4 Marks) JavaScript is an object-based scripting language which is used to create client-side dynamic pages. The programs in JavaScript language are called scripts. The scripts are written in HTML pages and executed automatically as the page loads. TypeScript is an open-source pure object-oriented programming language. It is a strongly typed superset of JavaScript which compiles to plain JavaScript. It is not directly run on the browser. It needs a compiler to compile and generate in JavaScript file. TypeScript source file is in “.ts” extension. TypeScript is the ES6 version of JavaScript with some additional features. Advantage of TypeScript over JavaScript  TypeScript always highlights errors at compilation time during the time of development, whereas JavaScript points out errors at the runtime.  TypeScript supports strongly typed or static typing, whereas this is not in JavaScript.  TypeScript runs on any browser or JavaScript engine. JavaScript doesn’t support data types, but with the help of TypeScript, we can use the data types feature in JavaScript. We can classify the TypeScript data type as following. 1. Static Types a. Built-in i. Number ii. String iii. Boolean iv. Void v. Null vi. Any vii. Union b. User-defined i. Array ii. Tuple iii. Enum iv. Functions v. Class vi. Interface 2. Generics 3. Decorators Explain some of the above Types with example (8 Marks) 2. Explain implementation of classes and modules in typescript with example Explain TypeScript Class with Example (6 Marks) Classes: In object-oriented programming languages like Java and C#, classes are the fundamental entities used to create reusable components. However, until ECMAScript 6 (also known as ECMAScript 2015), this was not the case with JavaScript. JavaScript has been primarily a functional programming language where inheritance is prototype-based. Functions are used to build reusable components. In ECMAScript 6, object-oriented class-based approach was introduced. TypeScript introduced classes to avail the benefit of object-oriented techniques like encapsulation and abstraction. The class in TypeScript is compiled to plain JavaScript functions by the TypeScript compiler to work across platforms and browsers. A class can include the following:  Constructor  Properties  Methods The following is an example of a class in TypeScript: // Declaration of Class class Employee { empCode: number; empName: string; constructor(code: number, name: string) { this.empName = name; this.empCode = code; } getSalary() : number { return 10000; } } // Create Object let emp = new Employee(100,”Steve”); Explain Modules with Example: (6 Marks) Modules: The TypeScript code we write is in the global scope by default. If we have multiple files in a project, the variables, functions, etc. written in one file are accessible in all the other files. For example, consider the following TypeScript files: file1.ts and file2.ts file1.ts var greeting : string = “Hello World!”; file2.ts console.log(greeting); //Prints Hello World! greeting = “Hello TypeScript”; // allowed The above variable greeting, declared in file1.ts is accessible in file2.ts as well. Not only it is accessible but also it is open to modifications. Anybody can easily override variables declared in the global scope without even knowing they are doing so! This is a dangerous space as it can lead to conflicts/errors in the code. TypeScript provides modules and namespaces in order to prevent the default global scope of the code and also to organize and maintain a large code base. Modules are a way to create a local scope in the file. So, all variables, classes, functions, etc. that are declared in a module are not accessible outside the module. A module can be created using the keyword export and a module can be used in another module using the keyword import. Implementation of Modules in TypeScript: // Employeemodule.ts: (Module 1) export class Employee { empCode: number; empName: string; constructor(name: string, code: number) { this.empName = name; this.empCode = code; } displayEmployee() { console.log (“Employee Code: ” + this.empCode + “, Employee Name: ” + this.empName ); } } let companyName:string = “XYZ”; // Employee1.ts (Module 2) import { Employee } from “./Employeemodule”; let empObj = new Employee(“Rani”, 1); empObj.displayEmployee(); 2) What are the important aspects of angular framework and discuss their contribution? Explain important aspects (6 x 2 Marks) Most important aspects of the Angular framework: 1. Modules In general, Angular apps use a modular design. Modules are highly recommended because they allow you to separate your code into separate files. This helps you keep your code files short and manageable while still allowing you to access the functionality from each one using the key terms import and export, with the following syntax: Import {Component} from ‘angular2/core’; Export class App {} 2. Directives Directives are JavaScript classes with metadata that defines the structure and behavior. Directives provide the majority of UI functionality for Angular applications. There are three major types of directives: a) Components: A component directive is a directive that incorporates an HTML template with JavaScript functionality to create a self-contained UI element that can be added to an Angular application as a custom HTML element. Components are likely to be the directives you use the most in Angular. (@Component in app.component.ts) b) Structural: You use structural directives when you need to manipulate the DOM. Structural directives allow you to create and destroy elements and components from a view. (*ngIf, *ngFor, *ngSwitch in app.component.html) c) Attribute: An attribute directive changes the appearance and behavior of HTML elements by using HTML attributes. (ngClass, ngStyle in app.component.html) 3. Data Binding One of the best features of Angular is the built-in data binding – the process of linking data from a component with what is displayed in a web page. Angular provides a very clean interface to link model data to elements in a web page. When data is changed on a web page, the model is updated, and when data is changed in the model, the web page is automatically updated. This way, the model is always the only source for data represented to the user, and the view is just a projection of the model. Ex.: Interpolation, Property Binding, Event Binding, Attribute Binding, Class Binding, Style Binding, Two-way Binding 4. Services Services are the major workhorses in the Angular environment. Services are singleton classes that provide functionality for a web app. For example, a common task of web applications is to perform AJAX requests to a web server. Angular provides an HTTP service that houses all the functionality to access a web server. The service functionality is completely independent of context or state, so it can be easily consumed from the components of an application. Angular provides a lot of builtin service components for basic uses, such as HTTP requests, logging, parsing, and animation. You can also create your own services and reuse them throughout your code. 5. Routing Routing in Angular allows the users to create a Single-Page Application (SPA) with multiple views and allows navigation between them. Users can switch between these views without losing the application state and properties. 3) Write in detail about angularCLI with all available commands with their purpose Explain about Angular CLI (2 Marks) Angular provides a powerful CLI that makes building out Angular applications a much more streamlined process. By using the CLI, you will quickly be able to generate new Angular applications, components, directives, pipes, and services. The following sections go over some of the most important tools available through the CLI. Explain Angular CLI Commands: (4 Marks) Angular CLI Command Options Command Alias Purpose ng new [name] Creates a new Angular application ng serve -o Builds and runs the angular application ng generate component [name] ng g c [name] Creates a new component ng generate directive [name] ng g d [name] Creates a new directive ng generate module [name] ng g m [name] Creates a module ng generate pipe [name] ng g p [name] Creates a pipe ng generate service [name] ng g s [name] Creates a service ng generate enum [name] ng g e [name] Creates an enumeration ng generate interface [name] ng g i [name] Creates an Interface Examples (6 x 1 Marks) Hint: (Give Example to the following) 1. Create Angular Project 2. Run Angular Project 3. Create Custom Component 4. Create Custom Attribute Directive 4. Create Custom Pipe 5. Create Service 4) Explain the procedure to create a new Angular Project and add the Bootstrap Explain about Software required and Installation Process (4 Marks) Angular is a widely used JavaScript framework for front-end development. Angular projects offer a great way to build single-page client applications by implementing HTML and Typescript functionalities. Procedure to Download and Install necessary Software 1. Install Visual Studio 2. Install Node JS from https://nodejs.org a. Check version of Node installed Go to command prompt  Verify Installed Node Version using node -v command b. Check version of NPM Installed Go to command prompt  Verify Installed NPM Version using npm -v command 3. Install Angular CLI Go to command prompt  Install Angular using npm install –g @angular/cli command a. Check Version of Angular Go to command prompt  Verify Installed Angular Version using ng v command Explain about Create of New Angular Project (8 Marks) Once Software is installed and ready, Angular Project will be created using the following procedure: 1. Create Angular Project Go to command prompt  Enter ng new [project name] Example: ng new demo Demo Folder will be created with all necessary folders and files 2. Install Bootstrap and Configure Bootstrap Go to command prompt  Go to Project Folder  Enter npm install bootstrap -save 3. Configure Bootstrap 5 into Angular App And navigate to your project and open angular.json file. And then add the following code into it; as follows: “styles”: [ “node_modules/bootstrap/dist/css/bootstrap.min.css” ], “scripts”: [ “node_modules/bootstrap/dist/js/bootstrap.min.js” ] 4. Open Project in Visual Studio Code Go to command prompt  Go to Project Folder  Enter code . 5. Run Project Go to command prompt  Go to Project Folder  Enter ng serve -o to run in default project in default brower. UNIT-II 1) Explain the concept of using constructor and external templates in angular Explain about Angular Components (6 Marks) Angular Components allow you to control how your application looks and functions through TypeScript code and an HTML template. Component Configuration: An Angular component consists of two main parts: 1. Definition in the decorator section The decorator section is used to configure the component, including things like the selector name and HTML template. Within the @Component decorator are several component configuration options as mentioned below: selector: This option allows you to define the HTML tag name used to add the component to the application via HTML. template: This option allows you to add inline HTML to define the look of the component. This is for when there won’t be very much code to add, and it’s helpful for when you don’t want extra files. templateUrl: This option allows you to import an external template file rather than inline HTML. This is helpful for separating a large amount of HTML code out of a component to help with maintainability. styles: This option allows you to add inline CSS to your component. Use it when only minor style changes are needed. stylesUrls: This option allows you to import an array of external CSS stylesheet(s). You should use this rather than styles when importing external CSS files. 2. Class section, which defines the logic. The class section enables you to give the component its logic, data, and event handlers, as well as export it to be used in other TypeScript files. Example: (6 Marks) 2) Write the process of component creation in angular project Explain Component (6 Marks) Angular is a SPA framework, and a view is made of one or more component. An Angular component represents a portion of a view. Angular Component = HTML Template + Component Class + Component Metadata HTML Template HTML template is nothing but a regular HTML code with additional Angular specific syntax to communicate with the component class. Class Essentially, a component class is a TypeScript class that includes properties and methods. Properties store data and methods include the logic for the component. Eventually, this class will be compiled into JavaScript. Metadata Metadata is some extra data for a component used by Angular API to execute the component, such as the location of HTML and CSS files of the component, selector, providers, etc. Explain the Procedure to Create Component (6 Marks) Generate Angular Component using Angular CLI You can create files for a component manually or using the Angular CLI command. Angular CLI reduces the development time. So, let’s use Angular CLI to create a new component. Use the following CLI command to generate a component. ng generate component Example: ng generate component contact The above command will create a new “contact” folder and app folder and create four files, as shown below. 1) contact.component.css is a CSS file for the component, 2) contact.component.html is an HTML file for the component where we will write HTML for a component, 3) contact.component.spec.ts is a test file where we can write unit tests for a component 4) contact.component.ts is the class file for a component. 3) Explain the concept of angular routing to single page application Explain about SPA (6 Marks) Single Page Applications (SPA) have a unique advantage that the user doesn’t lose context between page transitions. Yester-year applications reload the entire page as the user tries to navigate between views. The flicker not only affects user experience, it is also inefficient. An update to a section of the page needs the whole page to reload. SPAs address this problem. Angular provides Router API to manage a SPA which takes care of the following. 6. Allows a URL to represent a view in the application. 7. Create links that can perform view transitions. In other words, navigate from one view to the other. 8. Allow creating deep-links to specific pages in the application. Without routing and URL tied to a view, the user doesn’t have a way to deep-link to a screen and would need to go through the screens before it, every single time. Users can’t bookmark or save a link on the page. Routing solves this problem. 9. Routing also allows you to define the modular structure of your application. Angular Router Navigate To navigate different routes, use the Angular router as it provides methods to navigate different routes using routerLink. To navigate from one route to another, we need two Angular components. Each component contains a specific view. Explain Routing with Example (6 Marks) Example: Home In the above code, ‘/home’ is the path. Therefore, we need to map a specific component to the path /home. In Angular 13, there is an app-routing.module.ts module file. In that file, you can define the routes array that contains objects. We can define a different path and component in those objects, and angular will map the path to that component accordingly. So, it will render specific components to a particular path. const routes: Routes = [ { path: ‘home’, component: HomeComponent}, { path: ‘dashboard’, component: DashboardComponent } ]; 4) What is data binding. Describe the concept of interpolation and property binding Explain Data Binding (4 Marks) Data binding is the process of linking data from a component with what is displayed in a web page. When data in the component changes, the UI rendered to the user is automatically updated. Types of Data Binding:  Interpolation: Use double curly braces {{Variable}} to get values directly from the Component class.  Property binding: Use this type of binding to set the property of an HTML element.  Event binding: Use this type of binding to handle user inputs.  Attribute binding: This type of binding allows the setting of attributes to an HTML element.  Class binding: You can use this type of binding to set CSS class names to the element.  Style binding: You can use this type of binding to create inline CSS styles for the element.  Two-way binding: You can use this type of binding with data entry forms to receive and display data. Explain Interpolation (4 Marks) String Interpolation: String interpolation in Angular offers one-way Data Binding. It allows the angular template to receive data from the TypeScript template. You can effortlessly show data dynamically in angular HTML template (view). Example: import { Component } from ‘@angular/core’; @Component({ selector: ‘ng-app’, template: ‘

{{ university }}

’ }) export class NgComponent { university: string = ‘Malla Reddy University’; } Explain about Property Binding (4 Marks) In contrast to the attributes, which are defined in HTML, properties belong to the DOM. Since DOM is an object in JavaScript, we can get and set properties. Property binding is used to bind the data from property of a component to DOM elements. It is denoted by []. Example: app.component.ts: export class AppComponent { userName:string = “Peter”; } App.component.html: UNIT-III 1. Define Directives. What are the most common directives used in Angular Definition: (2 Marks) Directives extend the behavior of HTML, enabling you to create custom HTML elements, attributes, and classes with functionality specific to an application. Angular provides many built-in directives, which provide the capability to interact with form elements, bind data in a component to the view, and interact with browser events. Most common Directives using in Angular (10 Marks) Draw Sketch (2 Marks) Using Built-in Directives (2 Marks) Much of the Angular functionality that you need to implement in HTML elements is provided through built-in directives. These directives provide a wide variety of support for Angular applications. The following sections describe most of the Angular directives, which fall into three categories: Component: A directive with a template Directives in Angular is a .js class, which is declared as @directive. We have 3 directives in Angular. A @Component decorator is actually a @Directive decorator extended with templateoriented features. Whenever Angular renders a directive, it changes the DOM according to the instructions given by the directive. Directive appears within an element tag similar to attributes. Structural: A directive that manipulates elements in the DOM (6 Marks) a). *ngIf When this directive is present in an element, that element is added to the DOM if the value returns true. If the value returns false, then that element is removed from the DOM, preventing that element from using resources. Here is an example:

Choose ONE primary tradition or celebration in its own setting (The Inti Raymi festival (Sun Festival) – Peru) representing a culture different from your own country of origin that you experience (either in person or online). After experiencing it and learning more about it, identify and compare TWO secondary cultural traditions serving a similar purpose in other cultures, only ONE of the secondary traditions may be from your own country of origin. To reiterate, you will have one primary cultural event and two comparison/contrast events, all three from different places around the world.Overall, remember to watch, listen, observe, learn, compare, contrast, and research! Use 1st person in your paper, describe what you experience.Here are some questions to keep in mind:

Questions for primary cultural event:

What is the cultural event you experienced? Did you attend in person or watch it online?

What did you hear and see? What stood out to you while experiencing this event?

What was your initial impression of the culture when you experienced this event?

What did you learn about the event through research? Consider current practices and historical relevance.

Has there been outside influence on the cultural event?

Is the event being practiced the same now as it has been historically? Elaborate and exemplify.

Questions for secondary cultural events:

Be sure you have chosen two cultural events that serve a similar purpose to your primary cultural event in other parts of the world. (If your primary event is a festival of cultural history, your two secondary events should be festivals of cultural history as well. For example, you do not want to look for Viking Festivals in two additional places around the world. You want to look for festivals celebrating cultural identity in two other places in the world.)

What two other cultural events did you choose?

What is their country of origin? (Remember, one can be from your own country of origin, but the other must be from another part of the world.)

What purpose do two cultural events serve, and why is this similar to your primary cultural event?

How are they similar or different from your primary cultural event? (Consider food, music, dancing, singing, decorations, or dress.)

Wrap-up Questions:

Did you find any evidence of cultural influence, inspiration, or sharing across your chosen cultures?

What do your chosen cultures have in common? (Think about basic beliefs and behaviors of the people.)

Why do you think cultures around the world practice similar events and share common beliefs, and what does this say about human beings and culture, based on what you have learned this term?

In the workplace, you will often make decisions about communication as well as develop and deliver different types of professional communications. You will need to be able to assess the effect of social media and other digital technologies on business communication. In addition, you will need to be able to incorporate technology into your professional communication, using best practices, to create different communication artifacts. For this assessment, you will develop responses to professional business scenarios, which will demonstrate your ability to apply best practices for composing, revising, and delivering professional communication artifacts.

Preparation

Select 3 of the following scenarios, which were provided in Week 4:

• Solicitation for a Charity: You are writing a solicitation for a donation to a charity for animal rescue in your local area. Donations have been down in recent times due to issues such as COVID and inflation. The rescue organization is overflowing with surrendered animals and needs money to feed and house them while trying to find them new homes. Your goal is to engage your reader enough to read through your solicitation and to respond with some money to help the animal rescue.

• Employee Improvement Request: You are the manager of an employee at a delivery service who is not meeting job requirement expectations. Employee J has been showing up late for work, missing deliveries, and recently received a traffic citation. Your goal is to motivate the employee to make a positive change in their work behavior. You and your employee do not work at the same location.

• Complaint: You are writing to a company to complain about a shirt you ordered online that does not meet your needs. The design has started to peel off the shirt after one washing. You did not wear the item until after the return date had passed, so you didn’t notice the issue until recently. Your goal is to motivate the company to satisfy your request for a replacement or get your money back despite being against their normal policy.

• Advertise Your Brand: You have just received your Personal Training and Zumba certifications and have been hired by a local gym that is part of a national corporation. You need to encourage gym members to attend your Zumba classes and hire you to do personal training. You think that providing information on the benefits of weight training and cardio exercise is a great way to build your following.

• Circulate a Business Report: You have just completed a report about sales forecasts for your company’s products that you believe would be of great interest to not only your Sales Department manager, but also to other department leaders such as Manufacturing, Procurement, and Marketing, and even those in charge at the international corporate headquarters. You would like their buy-in to make some changes in corporate structure to meet the challenges that this increase in sales will present to the company.

• Update Your Clients and Share Changes in Health Benefits Coverage: It’s time for the annual health coverage enrollment, and you manage a number of companies that purchase their health insurance through your insurance agency. You need to inform Human Resources at these companies that some coverages are no longer available, and there has been a price increase across the board. You believe that your insurance agency still offers a competitive package, and your goal is to retain as many of these companies as customers as you can.

• Reply to a Job Ad: You have located an ad for a job that you want to apply for. You believe that your qualifications match those listed in the job ad. You need to show the employer that you are an excellent candidate for the job they are advertising.

Consider the following questions for each scenario you selected:

• Who is the audience for the business communication?
• What is the context for the business communication?
• What type of formatting is used for this communication channel?
• What types of resources will you use to review your business communication to ensure it is grammatically correct before finalizing it for delivery to the intended audience?

## Prepare Datasets

Before you start, you need to run the following command (in terminal or in notebook beginning with `!` ) to download the datasets:

“`sh

# This command will download required datasets and put it in “./datasets”.

python get_datasets.py

“`

## Implementation

You should run all code blocks in the following jupyter notebooks and write your answers to all inline questions included in the notebooks:

1. `knn.ipynb`

2. `linear_regression.ipynb`

3. `logistic_regression.ipynb`

4. `neural_network.ipynb`

5. `classification_nn.ipynb`

Go through the notebooks to understand the structure. These notebooks will require you to complete the following implementations:

1. `ece285/algorithms/knn.py`: Implement KNN algorithm

2. `ece285/algorithms/linear_regression.py`: Implement linear regression algorithm

3. `ece285/algorithms/logistic_regression.py`: Implement logistic regression algorithm

4. `ece285/layers/linear.py`: Implement linear layers with arbitrary input and output dimensions

5. `ece285/layers/relu.py`: Implement ReLU activation function, forward and backward pass

6. `ece285/layers/softmax.py`: Implement softmax function to calculate class probabilities

7. `ece285/layers/loss_func.py`: Implement CrossEntropy loss, forward and backward pass

You are required to go through all the modules (the ones that are already implemented for you as well) one by one to to understand the structure. This will help you when transitioning to deep learning libraries such as PyTorch. Here are some files that you should go through that are already implemented for you:

1. `ece285/layers/sequential.py`

2. `ece285/utils/trainer.py`

3. `ece285/utils/optimizer.py`

## Submission

### Things to keep in mind:

1. Edit **only** the parts that are asked of you. Do **not** change the random seed where it is set. This might not make it possible to get similar results.

2. Try to avoid `for` loops in all the implementations, the assignment can be solved without any for loops (vectorized implementation).

3. **Only answer questions and plot figures at givens cells**. TAs may miss your answer if you put it at the wrong cell.

After you complete all the functions and questions, you should upload the following files to Gradescope:

1. 7 `*.py` files that you have to implement (knn, linear_regression, logistic_regression, linear, relu, softmax, loss_func).

2. 5 notebook source `*.ipynb` files.

3. Exported PDF of notebooks (You could export jupyter notebook as PDF in web portal, do not need to install LaTeX packages) and merge them.

You should organize files like this:

1. Put all source files (7 python files and 5 notebooks) into a single `.zip` file then upload it on Gradescope.

2. Merge exported PDF of five notebooks into a single PDF file and upload it on Gradescope. Make sure to select correct page numbers for each question in Gradescope, otherwise TAs might miss the answers.

## Appendix

### How to Use Jupyter Notebook

Part of our skeleton code is provided using Jupyter notebook(`*.ipynb`). So there we provide a short instruction about how to use Jupyter Notebook.

Jupyter notebook is a powerfull interactive developement tool. Here we could Jupyter notebook file as notebook for short.

Jupyter notebook is pre-installed on Datahub, you can just use it via web-portal. You could also install it on your local machine. Here is the official install instruction([https://jupyter.org/install](https://jupyter.org/install)), which also included how to run it via terminal.

You may find on Jupyter website, they provide Jupyter Lab. Jupyter Lab is basically a new version of Jupyter notebook with more features and different interface. The basic usage is almost the same.

All notebooks are made up with multiple blocks. There are different kinds of blocks, the most common blocks are:

– Code block

– Markdown block

#### Code

For code block, you can write python code in code block, after finishing your code you could press run bottom on the jupyter note interface(normally on the top of the web interface). You can also use `Ctrl + Enter` or `Shift + Enter` to execute the block.

After you execute a block, Jupyter Notebook will execute your code with python and store all the function and variable you defined in memory. So you could still use those variables and function is other blocks.

For code blocks, you can think of jupyter notebook as a python console with an interface.

#### Markdown

Markdown block is where you can write some text.

When you execute Markdown block(the same method as Code block), your text will be compiled using Markdown grammar, instead of executing it with python.

In our assignment, we put some inline questions in notebooks, you are supposed to answer them with text.

#### Conclusion

In all, notebooks are basically some combination of code and text.

### How to Set Up Python Environment (Optional)

If you run the assignment on Datahub, you do **not** need to set up python environment. Our code is tested on Datahub.

If you run the assignment on your local machine or other environment and meet some problems, you **may** need to set up python environment.

We prepare a `requirements.txt` file (same versions as the datahub packages) for you to install python packages. You can install the packages by running the following command in terminal:

“`sh

pip install -r requirements.txt

“`

This should solve most package issues. But if you still have some problems, we recommend you to use conda environment. You can install anaconda or miniconda by following the instruction on [https://docs.anaconda.com/anaconda/install/index.html](https://docs.anaconda.com/anaconda/install/index.html). After you install it, you can run the following command to set up python environment:

“`sh

conda create -n ece285 python=3.9.5 # same python version as the datahub

conda activate ece285

pip install -r requirements.txt

“`
