Real‑Time Analytics Engine

At the core of DirectAxis lies a real‑time analytics engine built on stream‑processing frameworks. It applies statistical models, rule‑based thresholds, and machine‑learning algorithms to detect anomalies and predict failures. The engine supports both online learning - where models are updated continuously as new data arrives - and batch learning, which retrains models at scheduled intervals.

Predictive Maintenance Models

DirectAxis offers a library of pre‑trained predictive maintenance models that cover common asset types such as bearings, pumps, and electrical motors. These models are trained on anonymized datasets from thousands of installations and can be fine‑tuned to a specific customer’s environment. Model outputs include failure probability scores, recommended inspection intervals, and maintenance task prioritization.

Explainability and Trust

Recognizing the need for interpretability in industrial settings, DirectAxis incorporates explainability layers that provide visualizations of feature importance, decision paths, and anomaly causality. The platform uses SHAP (SHapley Additive exPlanations) values to explain model predictions, allowing engineers to verify and validate alerts before acting.

Edge Computing Integration

To support latency‑critical applications, DirectAxis offers edge computing modules that can be deployed on industrial gateways or embedded devices. These modules perform preliminary data filtering, anomaly detection, and predictive scoring locally. If an anomaly is detected, a low‑bandwidth alert is sent to the cloud for further analysis and archival.
