Unsupervised Anomaly Detection on Temporal Multiway Data

2020

Temporal anomaly detection looks for irregularities over space-time. Unsupervised temporal models employed thus far typically work on sequences of feature vectors, and much less on temporal multiway data. We focus our investigation on twoway data, …

Beyond the Known: Decision Making with Counterfactual Reasoning Decision Transformer

2024

Decision Transformers (DT) play a crucial role in modern reinforcement learning, leveraging offline datasets to achieve impressive results across various domains. However, DT requires high-quality, comprehensive data to perform optimally. In real-world applications, the lack …
