Web19 de jun. de 2024 · This paper presents TS2Vec, a universal framework for learning timestamp-level representations of time series. Unlike existing methods, TS2Vec performs timestamp-wise discrimination, which learns a contextual representation vector directly for each timestamp. We find that the learned representations have superior predictive ability. WebContraction hierarchies. In computer science, the method of contraction hierarchies is a speed-up technique for finding the shortest-path in a graph. The most intuitive …
