How Matching Networks Tackle Imbalance with Cosine Similarity and Attention

This article provides a comprehensive technical review of Matching Networks, covering cosine similarity mathematics, its transformations, the bias introduced by imbalanced support sets, and a range of mitigation strategies such as adaptive weighting, global distance‑matrix normalization, prior‑based weighting, hierarchical multi‑scale matching, hybrid learning architectures, and attention‑driven dynamic sample selection.
