A fun and absurd introduction to Vector Databases

Talkat Voxxed Days Zürich 2024 · on Thursday, 2024-03-07· [machine-learning, databases]

Shows a live stack: Unity + Spring Boot Kotlin frontend calling a Dockerized vector store using HNSW indexing and cosine similarity. Demonstrations include a weapon CSV turned into 384‑dim embeddings (nearest match cutoff 0.9, AK47 vs Desert Eagle distance ~0.7), D&D spell lookup improved by concatenated semantic fields, image search over 721 Pokémon (image match distance ~0.23 but noisy because embeddings favor color/shape), CLIP-based icon→effect mapping that produces usable particle effects, and a Whisper-based metal “Shazam” that fails on grunted vocals.
