fashion-mnist-classifier 0.1.0

An image classification model for Fashion MNIST using PyTorch Lightning.

Description

This project implements an image classification model based on the Fashion MNIST dataset, using PyTorch Lightning to structure the code in a modular and scalable way. The dataset is loaded directly from torchvision.datasets. The goal is to train a simple convolutional network that classifies images into 10 different clothing categories.
