Hercules Against Data Series Similarity Search
Karima Echihabi, Panagiota Fatourou, Kostas Zoumpatianos +2
We propose Hercules, a parallel tree-based technique for exact similarity search on massive disk-based data series collections. We present novel index construction and query answer…
Coconut: a scalable bottom-up approach for building data series indexes
Haridimos Kondylakis, Niv Dayan, Kostas Zoumpatianos +1
Many modern applications produce massive amounts of data series that need to be analyzed, requiring efficient similarity search operations. However, the state-of-the-art data serie…
Coconut Palm: Static and Streaming Data Series Exploration Now in your Palm
Haridimos Kondylakis, Niv Dayan, Kostas Zoumpatianos +1
Many modern applications produce massive streams of data series and maintain them in indexes to be able to explore them through nearest neighbor search. Existing data series indexe…
Return of the Lernaean Hydra: Experimental Evaluation of Data Series Approximate Similarity Search
Karima Echihabi, Kostas Zoumpatianos, Themis Palpanas +1
Data series are a special type of multidimensional data present in numerous domains, where similarity search is a key operation that has been extensively studied in the data series…
The Lernaean Hydra of Data Series Similarity Search: An Experimental Evaluation of the State of the Art
Karima Echihabi, Kostas Zoumpatianos, Themis Palpanas +1
Increasingly large data series collections are becoming commonplace across many different domains and applications. A key operation in the analysis of data series collections is si…
The Internals of the Data Calculator
Stratos Idreos, Kostas Zoumpatianos, Brian Hentschel +2
Data structures are critical in any data-driven scenario, but they are notoriously hard to design due to a massive design space and the dependence of performance on workload and ha…
