Technical articles on streaming forecasting, anomaly detection, concept drift, and adaptive AI — written by the engineers behind DriftMind.
Real-Time Forecasting Without Retraining
33,000–48,000 predictions per second on a single CPU. Benchmarked against Adaptive ARIMA and Triggered Prophet across four NAB datasets — with honest results. DriftMind wins on drift-heavy data; ARIMA wins on stable data. The full trade-off surface, explained.

The real bottleneck in production forecasting is not accuracy — it's the cost and latency of learning. The personal story behind DriftMind, from telecom-scale frustration to 33,000–48,000 predictions per second on a single CPU.
Read article →The Future of Forecasting Isn't Prediction — It's Adaptation
A survey of seven adaptive forecasting strategies from recent literature (2022–2024): online learning, meta-learning, adaptive normalisation, memory-based methods, and more. Why the field is moving from static models to living systems.
Read article →A Linear-Time Alternative to t-SNE for Dimensionality Reduction
Sine Landmark Reduction (SLR) — a deterministic O(N) algorithm that embeds 9,000 datapoints into 3D space in under two seconds. No iteration, no randomness, browser-native. Powers the 3D scatter plot in CSV X-Ray.

The retraining loop is architecturally incompatible with networks that change continuously. Amazon discontinued Lookout for Metrics. Microsoft is retiring Azure Anomaly Detector. What comes next — and why cold-start, CPU-only execution matters.
Read article →Reflexive AI: A Canonical Definition
Most AI systems are designed to think. Reflexive AI is designed to react — adapting in real time without retraining, replay buffers, or centralised inference. A manifesto for AI that evolves with the data, not behind it.
Read article →CSV X-Ray: Anomaly Detection and Forecasting for Excel and CSV Users
Not everyone who needs anomaly detection has a Python environment. CSV X-Ray brings DriftMind's forecasting and anomaly scoring to anyone with a spreadsheet — upload a CSV, get instant multi-feature analysis with interactive 3D visualisation.
Read article →Multi-Perspective Anomaly Detection (MPAD)
Single-variable anomaly detection misses the relationships between signals. MPAD analyses interdependent time series by correlating metrics across sensors, locations, and functional groups — surfacing root causes that individual thresholds can't see.
