This course comprehensively introduces JAX and Flax, two open-source libraries that have gained prominence for their efficiency, flexibility, and scalability in deep learning applications. 

In this course, you’ll explore deep learning principles and understand the unique features of JAX and Flax. You will learn the basics of JAX, optimizers using JAX and Flax, and loss and activation functions. You’ll also learn how to load datasets, perform classification using distributed learning, and use ResNet and LSTM models. In the end, you will complete a project for hands-on experience using JAX and Flax for transfer learning. 

By the end of the course, you’ll be proficient in implementing and customizing neural network models using JAX and Flax, equipped with hands-on skills in advanced optimization and distributed training.

Deep Learning with JAX and Flax

We will perform distributed training using JAX and Flax in this challenge. We have imported all the necessary libraries for you. 
# Challenge 1: Load the dataset
In the `/usr/local/notebooks` directory, we have a dataset in a zipped folder, `cars_and_bikes.zip`, containing images from two classes: cars and bikes. There are twelve images from each class, making a total of 24 images. Load the dataset using the image paths and labels (each image is named with the class it belongs to along with a serial number, e.g., `bike.0.jpg` or `car.4.jpg`). Moreover, define a `Dataset` class for loading it using the DataLoader to create training and validation sets.

Test your understanding of image classification and distributed training.
