Feature selection is a known technique to preprocess the data before performing any mining task. In multivariate time series (MTS) prediction, feature needs find both most related variables and their corresponding delays. Both aspects, certain extent, represent essential characteristics of system dynamics. However, variable delay for MTS challenging task when nonlinear noisy. this paper, multiattention‐based supervised method proposed. It translates weight generation problem into...

Ad hoc dataset retrieval has become an important way of finding data on the Web, where underlying problem is how to measure relevance a query. State-of-the-art solutions for this task are still lexical methods, which cannot capture semantic similarity. Semantics-aware knowledge-enhanced achieved promising results other tasks, have yet be systematically studied specialized task. To fill gap, in paper, we present empirical investigation implement and evaluate, two test collections, set...
