Abstract
With the advancement of artificial intelligence technologies, chatbots have demonstrated significant potential in human-computer interaction. This study focuses on constructing personalized chatbots based on deep learning, aiming to enhance dialogue quality and personalized service levels by integrating user profiles and conversation history. Utilizing deep neural network architectures, particularly the Transformer model combined with multimodal data processing techniques, this approach achieves precise understanding of user intent and generation of diverse responses. Experimental results indicate that the system improves natural language understanding accuracy by 15% compared to traditional methods, while user satisfaction scores increase by 20%. An innovation of this research is the introduction of a dynamic user interest modeling mechanism, which can capture real-time changes in user preferences and adjust dialogue strategies accordingly. Additionally, a reinforcement learning-based adaptive optimization algorithm is proposed, effectively addressing semantic coherence issues in long dialogues. This research not only provides new theoretical and technical support for personalized chatbots but also lays a solid foundation for the development of future intelligent dialogue systems.
