ACORN Algorithm for Filtered Vector Search
Advanced algorithm designed to make hybrid searches combining metadata filters and vector similarity more efficient, implemented in Apache Solr and other vector search systems.
Lazy Loading Filesystem
Modal Labs' FUSE-based filesystem implementation that loads container images and dependencies on-demand, enabling sub-second container startup times for GPU workloads.
Embedding API Latency
The time required to generate vector embeddings from text, images, or other data via API calls or local inference. Embedding latency significantly impacts RAG system performance, with typical ranges from 10ms (local, batch) to 500ms+ (API, single) depending on model size and deployment.
ANN Algorithm Complexity Analysis
Computational complexity comparison of approximate nearest neighbor algorithms including build time, query time, and space complexity. Essential for understanding performance characteristics and choosing appropriate algorithms for different scales.
SOAR (Spilling with Orthogonality-Amplified Residuals)
A major algorithmic advancement to Google's ScaNN that introduces controlled redundancy to the vector index, leading to improved search efficiency. Enables even faster vector search while maintaining or improving accuracy.
d-HNSW
An efficient vector search system designed for disaggregated memory architectures. d-HNSW optimizes HNSW for environments where compute and memory are separated, typical in modern cloud and distributed systems.
