Implementing a Siamese Network for Similarity Learning

this year hard (>1 hr) | siamese network similarity contrastive mnist

Build and train a **Siamese network** on a dataset like MNIST. The network takes pairs of images as input and learns to determine if they belong to the same class (a positive pair) or different...
Implementing a Graph Neural Network (GNN) Layer

this year hard (>1 hr) | network gnn graph node embedding

Implement a simple **Graph Neural Network (GNN) layer** for node classification on a small graph. The layer should aggregate features from a node's neighbors and combine them with the node's own...
