Researchers have developed HEPA, a novel self-supervised architecture for predicting critical events in multivariate time series data. This architecture uses a causal Transformer encoder pretrained with a Joint-Embedding Predictive Architecture (JEPA) to forecast future representations, enabling it to learn from unlabeled data. HEPA has demonstrated superior performance across 14 benchmarks, including water contamination and cyberattack detection, outperforming existing models like PatchTST and Chronos-2 with significantly less labeled data and fewer tuned parameters.
