-### What you'll need
+## Section 2: Building and Using AI System
 
-- [Node.js](https://nodejs.org/en/download/) version 18.0 or above:
-  - When installing Node.js, you are recommended to check all checkboxes related to dependencies.
-
-## Generate a new site
-
-Generate a new Docusaurus site using the **classic template**.
-
-The classic template will automatically be added to your project after you run the command:
-
-```bash
-npm init docusaurus@latest my-website classic
-```
-
-You can type this command into Command Prompt, Powershell, Terminal, or any other integrated terminal of your code editor.
-
-The command also installs all necessary dependencies you need to run Docusaurus.
-
-## Start your site
-
-Run the development server:
-
-```bash
-cd my-website
-npm run start
-```
-
-The `cd` command changes the directory you're working with. In order to work with your newly created Docusaurus site, you'll need to navigate the terminal there.
-
-The `npm run start` command builds your website locally and serves it through a development server, ready for you to view at http://localhost:3000/.
-
-Open `docs/intro.md` (this page) and edit some lines: the site **reloads automatically** and displays your changes.

 **Deep learning** is a **subset of machine learning (ML)** that utilizes **multilayered artificial neural networks** (also known as deep neural networks) to learn autonomously from large amounts of data, identify complex patterns, and make decisions or predictions with minimal human intervention. It forms the foundation for most artificial intelligence (AI) applications in use today. The term "deep" refers to the presence of multiple layers—typically **three or more hidden layers**, but often hundreds or even thousands—between the input and output layers in its neural network architecture.

 Artificial intelligence (AI) is a broad field of computer science and technology focused on creating machines and computer systems that can **simulate or replicate human intelligence**. Its fundamental goal is to enable software and machines to **reason, learn, and act in ways that would normally require human cognitive abilities**.

 **Machine learning (ML)** is a **subset of artificial intelligence (AI)** that focuses on enabling computers and machines to **learn from data and improve their performance on specific tasks without being explicitly programmed for every scenario**. Instead of following fixed, explicit instructions, ML systems use algorithms to **analyse large volumes of data, identify patterns, and then make predictions or decisions based on what they learn**.

-
-Docusaurus is a **static-site-generator** (also called **[Jamstack](https://jamstack.org/)**).
-
-It builds your site as simple **static HTML, JavaScript and CSS files**.
-
-## Build your site
-
-Build your site **for production**:
-
-```bash
-npm run build
-```
-
-The static files are generated in the `build` folder.
-
-## Deploy your site
-
-Test your production build locally:
-
-```bash
-npm run serve
-```
-
-The `build` folder is now served at [http://localhost:3000/](http://localhost:3000/).
-
-You can now deploy the `build` folder **almost anywhere** easily, **for free** or very small cost (read the **[Deployment Guide](https://docusaurus.io/docs/deployment)**).

-# Markdown Features
-
-Docusaurus supports **[Markdown](https://daringfireball.net/projects/markdown/syntax)** and a few **additional features**.
-
-## Front Matter
-
-Markdown documents have metadata at the top called [Front Matter](https://jekyllrb.com/docs/front-matter/):
-
-```text title="my-doc.md"
-// highlight-start
----
-id: my-doc-id
-title: My document title
-description: My document description
-slug: /my-custom-url
----
-// highlight-end
-
-## Markdown heading
-
-Markdown text with [links](./hello.md)
-```
-
-## Links
-
-Regular Markdown links are supported, using url paths or relative file paths.
-
-```md
-Let's see how to [Create a page](/create-a-page).
-```
-
-```md
-Let's see how to [Create a page](./create-a-page.md).
-```
-
-**Result:** Let's see how to [Create a page](./create-a-page.md).
-
-## Images
-
-Regular Markdown images are supported.
-
-You can use absolute paths to reference images in the static directory (`static/img/docusaurus.png`):
-
-```md
-![Docusaurus logo](/img/docusaurus.png)
-```
-
-![Docusaurus logo](/img/docusaurus.png)
-
-You can reference images relative to the current file as well. This is particularly useful to colocate images close to the Markdown files using them:
-
-```md
-![Docusaurus logo](./img/docusaurus.png)
-```
-
-## Code Blocks
-
-Markdown code blocks are supported with Syntax highlighting.
-
-````md
-```jsx title="src/components/HelloDocusaurus.js"
-function HelloDocusaurus() {
-  return <h1>Hello, Docusaurus!</h1>;
-}
-```
-````
-
-```jsx title="src/components/HelloDocusaurus.js"
-function HelloDocusaurus() {
-  return <h1>Hello, Docusaurus!</h1>;
-}
-```
-
-## Admonitions
-
-Docusaurus has a special syntax to create admonitions and callouts:
-
-```md
-:::tip My tip
-
-Use this awesome feature option
-
-:::
-
-:::danger Take care
-
-This action is dangerous
-
-:::
-```
-

-
-## MDX and React Components
-
-[MDX](https://mdxjs.com/) can make your documentation more **interactive** and allows using any **React components inside Markdown**:
-
-```jsx
-export const Highlight = ({children, color}) => (
-  <span
-    style={{
-      backgroundColor: color,
-      borderRadius: '20px',

-# Manage Docs Versions
-
-Docusaurus can manage multiple versions of your docs.
-
-## Create a docs version
-
-Release a version 1.0 of your project:
-
-```bash
-npm run docusaurus docs:version 1.0
-```
-
-The `docs` folder is copied into `versioned_docs/version-1.0` and `versions.json` is created.
-
-Your docs now have 2 versions:
-
-- `1.0` at `http://localhost:3000/docs/` for the version 1.0 docs
-- `current` at `http://localhost:3000/docs/next/` for the **upcoming, unreleased docs**
-
-## Add a Version Dropdown
-
-To navigate seamlessly across versions, add a version dropdown.
-
-Modify the `docusaurus.config.js` file:
-
-```js title="docusaurus.config.js"
-export default {
-  themeConfig: {
-    navbar: {
-      items: [
-        // highlight-start
-        {
-          type: 'docsVersionDropdown',
-        },
-        // highlight-end
-      ],
-    },
-  },
-};
-```
-
-The docs version dropdown appears in your navbar:
-
-![Docs Version Dropdown](./img/docsVersionDropdown.png)
-
-## Update an existing version
-
-It is possible to edit versioned docs in their respective folder:
-
-- `versioned_docs/version-1.0/hello.md` updates `http://localhost:3000/docs/hello`
-- `docs/hello.md` updates `http://localhost:3000/docs/next/hello`

-# Translate your site
-
-Let's translate `docs/intro.md` to French.
-
-## Configure i18n
-
-Modify `docusaurus.config.js` to add support for the `fr` locale:
-
-```js title="docusaurus.config.js"
-export default {
-  i18n: {
-    defaultLocale: 'en',
-    locales: ['en', 'fr'],
-  },
-};
-```
-
-## Translate a doc
-
-Copy the `docs/intro.md` file to the `i18n/fr` folder:
-
-```bash
-mkdir -p i18n/fr/docusaurus-plugin-content-docs/current/
-
-cp docs/intro.md i18n/fr/docusaurus-plugin-content-docs/current/intro.md
-```
-
-Translate `i18n/fr/docusaurus-plugin-content-docs/current/intro.md` in French.
-
-## Start your localized site
-
-Start your site on the French locale:
-
-```bash
-npm run start -- --locale fr
-```
-
-Your localized site is accessible at [http://localhost:3000/fr/](http://localhost:3000/fr/) and the `Getting Started` page is translated.
-
-:::caution
-
-In development, you can only use one locale at a time.
-
-:::
-
-## Add a Locale Dropdown
-
-To navigate seamlessly across languages, add a locale dropdown.
-
-Modify the `docusaurus.config.js` file:
-
-```js title="docusaurus.config.js"
-export default {
-  themeConfig: {
-    navbar: {
-      items: [
