Information-Enhanced Hierarchical Self-Attention Network for Multiturn Dialog Generation

2022 · IEEE Transactions on Computational Social Systems

Transformer structure has shown promising results in multiturn dialog generation. The self-attention mechanism can learn global dependencies but ignores local information, limiting the model’s ability to model context information. In this article, we propose an …
