Time-to-event modeling. Predicts when visitors will return, churn, or convert based on historical cohort data.
Cumulative sum and pruned exact linear time. Industrial-grade changepoint detection for traffic volume anomalies.
Finds recurring motifs and discords in time series. Detects bot patterns, periodic traffic spikes, and unusual sequences.
Weighted combination of all six algorithms. Produces a single confidence score and directional signal with explainable reasoning.
TypeScript backend on Fastify with schema validation. REST endpoints for fingerprint collection, visitor queries, and AI analysis.
