Tcm: A High-Precision Lossy Compression Algorithm for Time Series Data With Flexible Queue-Value Dynamic Grouping
Piecewise linear approximation (PLA) is pivotal for compressing time-series data under stringent error constraints. However, conventional PLA methods often struggle to reconcile the inherent conflict between aggressive compression ratios (CRs) and the preservation of complex local trends. In this article, we propose Tc...
