A1 – Fully-Connected Neural Nets (NumPy) on MNIST

This repository contains my solution for Assignment 1 of Deep Learning: a from-scratch Multi-Layer Perceptron (MLP) implemented in NumPy (no autograd). It covers the full training pipeline — forward pass, backward pass, Softmax cross-entropy loss, ReLU/Sigmoid activations, L2 regularization, and accuracy evaluation — on the MNIST dataset.

✨ Highlights

  • Pure NumPy implementation (no PyTorch/TensorFlow autograd)
  • Layers & utilities: affine_forward / affine_backward, relu_forward / relu_backward, sigmoid_forward / sigmoid_backward, softmax_loss
  • Support for L2 weight decay and basic optimizers (SGD / momentum / Adam—if enabled)
  • Clear separation of computations with cache values for backprop
  • Evaluation with accuracy metric on validation/test
