Scalable, Variable-Length Similarity Search in Data Series: The ULISSE Approach

Summary: ULISSE: first data-series index for variable-length similarity search. A novel length-flexible representation summarizes sequences of varying length, independent of Z-normalization, enabling efficient exact and approximate search via disk visits and in-memory scans, with orders-of-magnitude gains in space and time.
