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

It doesn’t mean anything. We can wait until the end of the training.


We need to add more epochs and train longer.

We see a significant difference between the training and validation accuracy during training. What can we understand from that?

We see a significant difference between the training and validation accuracy during training. What can we understand from that?

If we import a model with its pretrained weights and do not train it again by freezing its layers, it's not transfer learning.

The validation dataset doesn't affect training accuracy or loss since they don't contribute to the backpropagation during training.

The test dataset can affect the training results.

Bad gradients can cause an overfitting problem.
