NumPy Neural Network

What's npnn?

npnn is a a torch-like Python module for gradient descent based machine learning implemented with NumPy.

Work with npnn!

construct a image classification neural network with npnn

BTW, this is a course assignment of DATA620004, School of Data Science, Fudan University.

Task

Construct and Train a neural network on Fashion-MNIST to do image classification.

• Implement gradient backpropagation algorithm by hand,you can use numpy but DO NOT use pytorch or tensorflow to do autograd.

• Submit source code including at least four parts: model definition, training, parameters searching and testing.

Implementation

• dataset.py: provide Fashion MNIST dataset
• model.py: model definition
• train.py: model training
• search.py: parameters searching
• test.py: model testing
• utils.py: some misc function, such as save_mode
