Digit Classifier (MNIST)

Summary

The 'hello world' of deep learning: classify handwritten digits — a small, fast project that exercises the full PyTorch/TensorFlow training loop end to end.

• 1Build and train a small feedforward or CNN model on MNIST from scratch.
• 2Plot training/validation loss curves to check for overfitting.
• 3Push accuracy above 98% and explain what architecture changes got you there.
