Siamese networks

In this section, we'll discuss the Siamese Neural Networks for One-shot Image Recognition paper (https://www.cs.cmu.edu/~rsalakhu/papers/oneshot1.pdf). A Siamese network is a system of two identical base networks, as illustrated in the following diagram:

Siamese networks

The two networks are identical in the sense that they share the same architecture and the same parameters (weights). Each network is fed a single input sample and the last hidden layer produces an embedding vector of that sample. The two embeddings are fed to a distance measure. The distance is further processed to produce the final output of the system, which ...
