Learn and practice PyTorch, a framework for developing deep learning models.

Become a Deep Learning Professional

In this module, we’ll be introduced to the fundamentals of PyTorch: autograd, model classes, datasets, data loaders, and more. We’ll develop models and understand them step-by-step. We'll understand the reasoning behind the code and how to avoid some common pitfalls and errors along the way.
By the time we finish this module, we’ll have a thorough understanding of the concepts and tools necessary to start developing and training our own models using PyTorch.

Deep Learning with PyTorch

## What to expect from this chapter

In this chapter, we will:

- Build a model for **binary classification**.

- Understand the concept of **logits** and how it is related to probabilities.
- Use **binary cross-entropy loss** to train a model.
- Use the loss function to handle **imbalanced datasets**.
- Understand the concepts of **decision boundary** and **separability**.
- Learn how the **choice of a classification threshold** impacts evaluation metrics.
- Build **ROC** and **precision-recall** curves.

## Imports

For the sake of organization, all libraries needed throughout the code and used in any given chapter are imported at the very beginning. For this chapter, we will need the following imports:
