Twitter's Anomaly Detection in Pure Python

Easier CUSUM control charts. Returns simple CUSUM statistics, CUSUMs with control limit calculations, and function to generate faceted CUSUM Control Charts

Different flavours of CUSUM for change point detection.

Calibrated simulation and detectors for MES-embedded carbon-intensity monitoring of energy anomalies in machining-style processes. Characterizes the adaptive-baseline inertia blind spot and proposes an event-anchored + residual-CUSUM detector that closes it. Reproducible: code, raw sweep data, and figure scripts.

Anomaly Detection in Sensor Data (LIT101) from Secure Water Treatment (SWaT) testbed . Demo of CUSUM and MLP methodologies.

This repository represents additional control charts, various plans and variables that are used within the chart scope using Minitab software

CUSUM is the cumulative sum of the samples and CUMEAN is the cumulative sum of the updated samples with their mean. CUSUM and CUMEAN can detect relatively small changes in a process mean. They can be more useful in the time series dataset.

NCIs Project 2024/25

Changepoint detection toolkit for offline and online in Rust with Python bindings

Streaming anomaly detection in Rust — detectors, calibration, SOC triage. Powers eBPFsentinel

A robust Federated Learning framework implementing the novel FedCADS-UCB algorithm. Engineered for resilient client selection using CUSUM drift detection, adaptive multi-armed bandits, and hierarchical clustering to maintain high accuracy (>95%) during concept drift and label poisoning attacks.

Adversarial game-integrity system that detects rigged casino games and advantage players using sequential hypothesis testing (SPRT/CUSUM) and anomaly detection.

A Python library to address the Change Detection problem using the CUSUM and CPM methods, implemented with NumPy and SciPy. The CPM implementation closely matches the R version, providing a solid alternative for Python users.

A hardware–software co-design of the CUSUM streaming anomaly detector. Includes hardware modules, a software reference implementation, and Python tools for validating correctness and profiling performance across platforms.
