Probabilistic Anomaly Detection in Time Series Data

anomaly-detection time-series statistical-methods machine-learning
Prompt
Develop a sophisticated anomaly detection framework for time-series data using statistical methods in JavaScript. Create algorithms that can detect complex statistical anomalies using techniques like Gaussian Mixture Models, Isolation Forests, and kernel density estimation. The system should support multi-dimensional time series, handle streaming data, and generate real-time alerts with configurable sensitivity thresholds.
