“The learning paths on Dataquest are incredible. They give you a direction through the learning process – you don’t have to guess what to learn next.”

Otávio Silveira

Data Analyst @ Hortifruti

Course overview

The course has several objectives. First, you will learn what a GPT model is (Generative Pre-trained Transformer) and how it operates. Additionally, the course will help you refresh your knowledge of linear algebra and calculus concepts that are crucial for deep learning. You’ll learn how to manipulate matrices, perform vector calculus, and solve optimization problems.

Finally, you will learn how gradient descent is used in deep learning. You’ll learn how to train a linear regression model using gradient descent, and you’ll learn how gradient descent is used to optimize neural network parameters. You’ll also gain practical experience by implementing gradient descent algorithms from scratch using Python.

By the end of this course, you’ll have a solid understanding of the fundamental concepts of deep learning. You’ll be well-prepared to continue your deep learning journey and move on to more advanced topics such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs), leading up to training your own GPT model.

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”


Jessica Ko

Machine Learning Engineer at Twitter

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”


Victoria E. Guzik

Associate Data Scientist at Callisto Media

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
