Segmented Angular Pre-Processing for Accurate and Efficient In-Memory Vector Similarity Search

Vector similarity search (VSS) is a fundamental operation in modern AI applications, including few-shot learning (FSL) and approximate nearest neighbor search (ANNS). Cosine similarity is widely regarded as the optimal metric for VSS. However, VSS incurs substantial energy and computational overhead...
