Perception / Signals

From classical signal theory to physiological intelligence.

Signals define the perception layer of Neuroide. This topic covers how information is gathered from raw measurements and sensory streams across digital signal theory, biosignals, physiological sensing, EEG, EDA, ECG, PPG, and multimodal data.

Scope
Theory

Sampling, transforms, filtering, stochastic signals, spectral estimation, wavelets, and state-space views of time series.

Physiology

ECG, EEG, EMG, EDA, respiration, PPG, sleep data, wearable sensing, and multimodal physiological measurement.

Modeling

Sequence learning, feature engineering, self-supervision, transfer across devices, and subject-specific adaptation.

Applications

Monitoring, anomaly detection, digital health, and machine intelligence grounded in noisy human-centered data.
