Data Preprocessing and Feature Extraction
a.
EEG Data Preprocessing
Denoising and Signal Enhancement: Utilize signal processing techniques to denoise and enhance EEG data, ensuring the clarity and stability of the data.
Feature Extraction: Extract key features from EEG data using machine learning algorithms, such as emotional state, attention level, and cognitive activity patterns. These features serve as the foundation for subsequent analysis and model training.
b.
Data Integration
c.
Multi-source Data Integration: Integrate EEG data features with users' basic information and personalized profiles to create a comprehensive user data archive. This archive includes users' physiological, psychological, and behavioral characteristics, providing comprehensive personalized information.
Large Language Model Training and Personalization
a.
Initial Model Training
Large Language Model Foundation: Use the pre-trained large language model Morpheus as the base model. This model, trained on a vast amount of general text data, possesses strong natural language processing capabilities.
Personalized Data Fine-tuning: Fine-tune the large language model using users' personalized data and initially collected EEG data. The goal of fine-tuning is to enable the model to generate text that conforms to users' language styles and expression habits.
b.
Real-time Interaction and Dynamic Adjustment
Real-time EEG Data Input: During user interaction with Avatar Intelligence, continuously collect users' EEG data to provide immediate emotional and cognitive feedback.
Dynamic Model Adjustment: Adjust the large language model's generation strategy dynamically based on real-time EEG data input. For example, when users exhibit a happy emotion, Avatar Intelligence can use more positive and cheerful language; when users show confusion or anxiety, Avatar Intelligence can provide support and comfort.
Emotional Synchronization and Cognitive Mapping
a.
Emotional Synchronization
Emotional State Recognition: Real-time recognition of users' emotional states (e.g., happiness, sadness, anxiety) using deep learning models. These emotional states serve as critical references for generating dialogue content.
Emotional Response Generation: Generate dialogue content that aligns with the recognized emotional states. For example, when users feel frustrated, Avatar Intelligence can offer comforting and encouraging words; when users are happy, Avatar Intelligence can share in their joy.
b.
Cognitive Mapping
Cognitive Activity Analysis: Analyze users' cognitive activity patterns (e.g., logical thinking, creative thinking, and decision-making processes) using EEG data. These analysis results help understand users' cognitive styles and decision-making logic.
Cognitive Mapping Generation: Map the analyzed cognitive patterns into the large language model, enabling Avatar Intelligence to mimic users' cognitive processes. For instance, when users think about a complex problem, Avatar Intelligence can exhibit a similar cognitive process and provide suggestions and solutions that align with users' thinking logic.
Continuous Learning and Optimization
a.
Data Collection and Feedback
Interaction Data Collection: Collect conversation content, EEG data, and user feedback during each interaction with Avatar Intelligence. The system analyzes these data to identify strengths and weaknesses in Avatar Intelligence's interactions.
User Feedback Analysis: Periodically analyze subjective user feedback and objective data to identify highly satisfactory interaction patterns and areas needing improvement.
b.
Model Optimization and Update
Continuous Model Training: Regularly update and optimize the large language model based on collected interaction data and user feedback. Through continuous learning, Avatar Intelligence can gradually improve its synchronization with users' thoughts and emotions.
Personalized Model Improvement: Continuously adjust and optimize the personalized model to ensure that Avatar Intelligence consistently reflects users' personality traits and cognitive styles. Through ongoing improvements, Avatar Intelligence will become increasingly attuned to users, providing more intelligent and personalized interactive experiences.
