**1 Principle of Continuous Emotion Recognition from Heart Rate Variability Signals** Heart Rate Variability (HRV) refers to the small fluctuations in the intervals between heartbeats, reflecting the regulatory capacity of the Autonomic Nervous System (ANS). Emotional changes affect HRV signals through the sympathetic and parasympathetic nervous systems: – **Sympathetic Activation**: Emotions such as tension and anxiety decrease the high-frequency component (HF) of HRV and increase the low-frequency component (LF). – **Parasympathetic Activation**: Relaxation and pleasant emotions increase the HF component and decrease the LF/HF ratio. Emotion recognition from HRV signals relies on modeling the correlation between time-domain (e.g., SDNN), frequency-domain (e.g., LF/HF), and nonlinear features (e.g., sample entropy) with emotional states. — **2 Data Processing Workflow** **Signal Preprocessing** – Acquire raw signals through ECG or PPG sensors, filtering to remove motion artifacts and baseline drift. – Use peak detection algorithms (e.g., Pan-Tompkins) to locate R waves and calculate the RR interval sequence. – Interpolate to correct missing or abnormal values (e.g., cubic spline interpolation) and resample to a uniform frequency (typically 4Hz). **Feature Extraction** – **Time-Domain Features**: SDNN (standard deviation), RMSSD (root mean square of successive RR interval differences). – **Frequency-Domain Features**: Calculate LF (0.04-0.15Hz) and HF (0.15-0.4Hz) power using the Welch periodogram method. – **Nonlinear Features**: Poincaré plot (SD1/SD2), multiscale entropy (MSE). — **3 Emotion Model Construction** **Feature Selection** – Use Recursive Feature Elimination (RFE) or mutual information methods to select features highly correlated with emotion labels. – Standardize features (Z-score) to reduce individual differences. **Model Training** – **Discrete Emotion Classification**: Use models such as SVM, Random Forest, etc., with labeled data containing emotion categories (e.g., happy, sad). – **Continuous Dimension Prediction**: Use LSTM or CNN to process time series and predict continuous values of Valence and Arousal. **Validation Methods** – Leave-One-Out Cross-Validation (LOOCV) or time-segment validation to assess accuracy, F1 score, or Mean Squared Error (MSE). — **4 Application Optimization Directions** – **Real-Time Improvement**: Segment signals using a sliding window (e.g., 5-minute window, 50% overlap) and deploy lightweight models on edge computing. – **Personalized Adaptation**: Use transfer learning or federated learning to address individual physiological differences. – **Multimodal Fusion**: Combine EEG and Galvanic Skin Response (GSR) to enhance recognition robustness. Code Example (Python Feature Extraction):
import neurokit2 as nk # Calculate HRV features hrv_features = nk.hrv(peaks, sampling_rate=1000, frequency_domain_method='welch') print(hrv_features[['HRV_LF', 'HRV_HF', 'HRV_SDNN']])
