CIVET: Exploring Compact Index for Variable-Length Subsequence Matching on Time Series

Summary: CIVET introduces UPAA, a uniform PAA representation that aligns features across variable-length subsequences while preserving lower-bounding. Builds a compact index by grouping adjacent/similar subsequences and uses pruning+filtering to enable exact (no false dismissals), scalable, faster variable-length matching.
