This invention discloses a method for constructing AI memories and generating virtual personalities based on full-volume dialogue storage, relating to the fields of
artificial intelligence and human-computer interaction. During operation, the
system establishes a structured storage mechanism for full-volume dialogues, constructing a traceable multi-dimensional AI
memory bank. It extracts multi-dimensional features such as semantic preferences, emotional tendencies, and behavioral patterns through a deep semantic analysis model, aggregating them into high-dimensional memory representations with temporal evolution characteristics. A dynamic update
mechanism based on memory strength, novelty, relevance, and decay functions is implemented to achieve
adaptive optimization of the
memory bank. A personality mapping model is constructed, mapping memory representations to a low-dimensional personality vector space composed of openness, agreeableness, conscientiousness, emotional stability, and autonomous evolutionary tendencies. Based on the personality vectors, the
system regulates the AI's language style, emotional expression, and decision-making preferences, and combines these with
user feedback signals to form a closed-loop evolutionary mechanism of "memory-personality-feedback."
