This repository contains uncompleted and completed assignments from the "Deep Learning for Computer Vision" course offered by the University of Michigan in the Winter of 2022.

All course materials can be found here.

Please note that this repo exclusively contains my self-learning materials and is not officially affiliated with the course.

If you need the solutions, please check the solutions branch.

A1 include 2 questions:

Q1: PyTorch 101. Walk you through the basics of working with tensors in PyTorch.

Q2: k-Nearest Neighbor classifier. Walk you through implementing a kNN classifier.

The goals:

• Develop proficiency with PyTorch tensors
• Gain experience using notebooks on Google Colab
• Understand the basic Image Classification pipeline and the data-driven approach (train/predict stages)
• Understand the train/val/test splits and the use of validation data for hyperparameter tuning
• Implement and apply a k-Nearest Neighbor (kNN) classifier
• Learn how to test your implementation on Autograder

A2 include 3 questions:

Q1: Linear Classifiers. Walk you through implmenting SVM and Softmax classifier.

Q2: Two-layer Neural Network. Walk you through implementing a two-layer neural network-based classifier.
