Implementing a Siamese Network with Triplet Loss

this month hard (>1 hr) | siamese loss learning triplet metric

Building on the previous exercise, let's switch to **Triplet Loss**. This loss function is more powerful as it enforces a margin between an anchor-positive pair and an anchor-negative pair. The...

Implementing a Siamese Network for Similarity Learning

this month 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...

Implement a Siamese Network

this month hard (>1 hr) | pytorch siamese cnn metric learning

Implement a Siamese network for MNIST digit similarity: - Two identical CNNs sharing weights. - Contrastive loss function. - Train on pairs of digits (same/different). Evaluate on test pairs.
