Image classification and object detection have gained widespread use in recent years. Content categorization and monitoring, disease diagnosis from medical images, identifying terrain in satellite images, and detecting road elements for self-driving cars are classification problems at their core. PyTorch is a popular framework for these tasks—offering a useful mix of user-friendliness, deep learning functionalities, customization, and optimization.

In this course, you will cover the fundamentals of classification and object detection models and apply them to actual datasets using PyTorch. You’ll learn popular architectures and how to implement and fine-tune them for better results. Finally, you’ll learn to convert models to ONNX and OpenVINO to deploy in edge devices.

By the end of this course, you will have acquired the necessary skills to be able to use PyTorch for image identification and object detection in real-world applications

Using PyTorch for Image Classification and Object Detection

# Underfitting & overfitting

**Underfitting** refers to the model's failure to learn. Somehow, the model can't improve itself, and we see that training and validation accuracy get stuck without getting any better with further iterations. A primary reason for this is to have vanishing or exploding gradients. As we mentioned, both problems are about having bad values to update weights, which causes the learning to stop.

> **Note:** The figures below show us what happens if we set `LEARNING_RATE = 1.0`.
