# Machine Learning and AI

## What is the course about?

Are you ready to dive into the world of Machine Learning? This course helps you build a strong foundation, covering supervised learning methods like regression and classification, as well as unsupervised techniques such as clustering and dimensionality reduction.

Hands-on practice will give you the skills needed to tackle real-world challenges. The course ends with a final project where you can apply everything you’ve learned. After completing this course, you’ll be ready to join the Data Circle and continue your learning journey!

## Why should you take this course?

* **Content -** Learn how to use machine learning models and how to build and apply them. You learn about Regression, Clustering, and Classification models. You use libraries and manage code with Git & GitHub.&#x20;
* **Final Project -** Apply your knowledge to a real-world Machine Learning project.
* **Your Start -** This course is the perfect starting point for your journey toward becoming a Data Analyst, Data Scientist or Machine Learning Engineer. By the end of the course, you will have a solid foundation in Python, a GitHub portfolio showcasing your projects, and a ReDI Certificate. Afterward, you can advance your skills by enrolling in the Data Circle course.
* **Industry Experts -** The teachers are volunteers from the industry. They are experts in web development and will help you start your journey toward a tech career!&#x20;

## Learning Format

In the two weekly sessions, teachers introduce key concepts to the students and practice them with small exercises and live coding. Next to the two sessions, students are asked to apply the newly learned concepts in weekly homework and a final project.&#x20;

## Weekly Homework

Every Wednesday, students will receive homework to be submitted by Sunday evening. Homework review is part of the Monday session. There is a requirement for students to complete 80% of the homework throughout the course in order to graduate. Homework is not graded.

{% hint style="warning" %}

## **ReDI Style**

This course is about active participation. You will be asked to work independently on weekly homework to apply your newly learned skills. You are in charge of your learning journey. Are you ready to work hands-on and participate actively in the sessions? Then join us!&#x20;

## A typical week

<details>

<summary>Monday 19:00 - 21:00</summary>

Every Monday from 19:00 to 21:00, you have an online session in which you discuss your homework and where you will be introduced and practice new concepts.

</details>

<details>

<summary>Wednesday 19:00 - 21:00</summary>

Every Wednesday from 19:00 to 21:00, you have an online session where the volunteer teachers introduce you to new concepts. They will share the weekly homework with you in this session.

</details>

<details>

<summary>Thursday - Monday</summary>

You work on your weekly homework. That means you will be coding hands-on by yourself! If you run into problems, you can contact your class on Slack. You upload your homework before the Monday session.
