What it does
This is a collection of tutorial notebooks from Udacity's Deep Learning Nanodegree course. Notebooks are interactive documents that mix explanations with code you can run step by step. They use PyTorch, a popular toolkit for building AI models.
The lessons walk you through building different kinds of neural networks (computer programs loosely inspired by the brain that learn from examples). Topics include recognizing handwritten digits and images, judging whether a movie review is positive or negative, generating new images, and turning summer photos into winter ones.
It also includes the starting code for the course projects, such as predicting bike rentals, classifying dog breeds from photos, generating TV scripts, and creating new face images. There is extra material on TensorFlow and Keras, two other AI toolkits.
Who it's for
Learners who know some Python and want to understand how deep learning works by building models themselves.
Can I use it without coding?
Developers only. The lessons involve writing and running Python code in notebooks after setting up a programming environment from the command line. New to this? Start here.
