KAIROSHOPE: A NEXT-GENERATION TIME-SERIES FOUNDATION MODEL FOR SPECIALIZED CLASSIFICATION VIA DUAL-MEMORY ARCHITECTURE
KairosHope introduces a novel Time Series Foundation Model (TSFM) with a dual-memory architecture (HOPE Block: Titans for short-term, CMS for long-term retention) and a Hybrid Decision Head for enhanced classification precision. It addresses the limitations of traditional TSFMs, such as quadratic attention and the neglect of classical statistical knowledge. Pre-trained on the Monash archive using Masked Time Series Modeling (MTSM) and InfoNCE contrastive learning, KairosHope achieves superior performance in tasks with strong temporal causality (e.g., HAR, Sensor data) on the UCR benchmark, establishing an efficient framework for adapting foundation models to specialized time series analysis.

Impact on HAR and Sensor Data
KairosHope demonstrates significant superiority in Human Activity Recognition (HAR) and Sensor datasets, achieving 91.333% and 89.6% mean accuracy respectively. This success is attributed to its ability to model strict temporal causality and long-term historical dependencies effectively through the HOPE Block's dual-memory system and the enrichment provided by the hybrid decision head.
Outcome: Improved accuracy and robustness for time-critical, causally-dependent time series applications.
Limitations in Geometric Invariance
Despite its strengths, KairosHope exhibits limitations when applied to IMAGE-type datasets, where performance remained stagnant (66.211% mean accuracy). This suggests an incompatibility of temporal inductive bias, as the HOPE block is optimized for strict temporal causality, which is not inherent in 1D image contours. The deterministic statistical features from tsfeatures also lack representational utility for geometric invariance problems. Future work aims to develop specific feature extraction modules for such data.
