Contrastive learning is why a text query can find the right moment in hours of footage without labelled training data. This volume covers contrastive learning in depth as part of its search section: shared image-text embeddings, zero-shot recognition, model artifacts, and search and RAG over a video archive. Written by Nikolay Sapunov, CEO at Fora Soft.
