Facial expression and emotion recognition is a core technology leveraging computer vision and deep learning. The system preprocesses facial images, extracts key points (Dlib, MTCNN), and uses an improved Convolutional Neural Network (CNN) trained on FER 2013 and CK+ datasets. The CNN structure includes convolutional, pooling, and fully connected layers, with ReLU activation and Softmax for classification. The loss function is cross-entropy, optimized by Adam (learning rate 0.001). Data augmentation techniques like rotation, scaling, and flipping enhance model generalization. Multimodal fusion (speech, text) further refines accuracy.

Classroom behavior analysis assesses student engagement using computer vision and machine learning. The system collects student action videos in classrooms and annotates typical behaviors such as raising hands or bowing heads. Data preprocessing includes cleaning, Z-score normalization, and recursive feature elimination (RFE) for feature selection. Behaviors are classified using Support Vector Machine (SVM) with an RBF kernel (gamma=0.1, C=1.0) and Random Forest (100 trees, max depth 10, min samples split 2) to identify patterns like active interaction or passive avoidance. Multi-object tracking (SORT, DeepSORT) mitigates tracking loss, and context analysis improves recognition accuracy.

Classroom Behavior Analysis Accuracy (SVM/RandomForest)
Attention monitoring employs physiological signal collection and machine learning in real-time. Eye trackers capture eye movement trajectories, fixation points, and times. Heart rate sensors collect HRV data, providing insight into psychological states. Key features extracted include fixation time, saccade speed, and pupil size. Attention is quantified using the HRV formula: HRV = sqrt(sum((RRi - RR_avg)^2) / (N-1)), where RRi is the i-th RR interval. Machine learning methods like K-Nearest Neighbors (KNN) or Neural Networks (NN) classify attention into states (high, medium, low). A comprehensive attention score is calculated as: Score = 0.4×HRV_norm + 0.3×Eye_Fixation + 0.3×Head_Pose_Stability.

Attention Level Monitoring Accuracy (HRV+Eye Fusion)
The system operates on three layers: data collection, processing, and visualization feedback. Data collection uses wide-angle cameras for expressions/movements, eye trackers for pupil/fixation data, heart rate sensors for HRV, and directional microphones for voice/emotion analysis. Data undergoes alignment, standardization, and Kalman filtering. Core analysis includes improved CNN for facial expressions, SVM/RandomForest for behavior, and HRV+Eye fusion for attention. Multimodal fusion integrates these insights. Real-time processing uses Apache Kafka and Spark Streaming for millisecond delays. Visualization includes heatmaps, radar charts, and attention curves with intelligent early warnings and teaching plan support.
