Dumpy: A Compact and Adaptive Index for Large Data Series Collections

Summary: Dumpy is a compact, adaptive multi-ary index for large data-series collections, enabling fast index building and high-accuracy search. By addressing iSAX limitations—proximity-compactness trade-offs and skew—via adaptive node splitting and Dumpy-Fuzzy duplication, it achieves better efficiency, scalability, and accuracy.
