“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.”

Data Analyst @ Hortifruti

Course overview

First, you’ll learn the relevance of CNN in the field of computer vision, and you’ll implement both basic and complex CNN for multi-class classification tasks in TensorFlow. You’ll then advance to understanding how a CNN model learns different features across its layers and attempts to improve the model’s performance.

You’ll learn different regularization techniques to tackle overfitting when building deep learning models in TensorFlow.

Next, you’ll see the importance of complicated models like ResNet for computer vision tasks, and you’ll implement a ResNet-based, pre-trained model on advanced CNN architecture.

Finally, you’ll learn how to use previously trained models for other similar tasks on a different dataset than the original model was trained on.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. At the end of the course, you’ll apply your new skills to a project to create a computer vision model that can detect if a patient has pneumonia using an X-ray scan.

Business Analyst at Aditi Consulting

“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!”
