This 2022 paper introduces Persona-Adaptive Attention (PAA), a specialized framework designed to improve dialogue systems by better integrating persona descriptions and conversational history. The researchers address the challenge of balancing these two information sources by using a weighting and masking mechanism that dynamically prioritizes relevant details while filtering out redundant data. Their architecture utilizes separate transformer encoders for persona and context, fused within a decoder to ensure responses remain consistent and engaging. Experiments on the ConvAI2 dataset show that PAA significantly outperforms larger models like GPT-2, particularly in low-resource settings where training data is limited. Ultimately, the framework offers a data-efficient solution that achieves high persona consistency and response quality without requiring external datasets or overly complex training procedures.
