Definition

The Ki Index is a time-varying metric, Ki(t), that summarizes the state of a person’s physiological signals into a single interpretable quantity. It is computed from features extracted across multiple sensing modalities.

Physiological Basis

Ki integrates information from cardiovascular, thermal, and motion-related signals, among others. By combining these channels, the Ki Index reflects coordinated changes in physiology rather than isolated measurements.

Computation Framework

AiKiology defines a reproducible workflow for Ki computation: feature extraction, scaling, weighting, and aggregation into Ki(t) and composite Ki metrics. The framework is documented to support scientific review and replication.

Applications

The Ki Index can be used for health and wellness monitoring, research studies, and exploratory analysis of physiological states. AiKiology focuses on transparent methods and clear limitations to support responsible use.
