  "title": "Bayesian Tensor Autoencoder with Physics-informed Predictive Prior for Multi-dimensional Time Series Anomaly Detection",
  "summary": "The method replaces reshaping-based uni-/multi-variate anomaly detectors with a tensor autoencoder that fuses reconstruction and prediction through a Bayesian predictive prior regularized by tensor low-rank decomposition. It costs additional model complexity: a Bayesian fusion mechanism, physics-informed network constraints, and tensor decomposition machinery that must be implemented and tuned. It can fail when the low-rank assumption does not hold in the data, when the predictive prior is miscalibrated, or when anomalies are subtle enough that enhanced normal-data modeling still reconstructs them.",
  "rationale": "This is a specialized time-series anomaly detection method outside the reader's LLM inference, training, and agent work, and the abstract reports no quantified improvement over baselines.",
