FLEA: Frequency-based Lossless Encoding Algorithm for Periodic Time Series
Summary: FLEA is a lossless compressor for periodic time series that quantizes frequency-domain coefficients while encoding time-domain residuals. An energy-based rate-optimal search and adaptive coefficient/residual partitioning deliver state-of-the-art compression with fast decoding, integrated into Apache TsFile.
