Challenge: Existing models combine previous questions for conversation understanding and only employ recurrent neural networks (RNN) for reasoning.
Approach: They propose a multi-perspective convolutional cube model that integrates 1D and 2D convolutions with recurrent neural networks (RNN) to understand context from different perspectives.
Outcome: The proposed model is based on the Conversational Question Answering (CoQA) dataset and achieves state-of-the-art results.

Dialog Generation Using Multi-Turn Reasoning Neural Networks (N18-1)

Copied to clipboard

Challenge: Existing methods for dialog generation are limited and short at generalization.
Approach: They propose a generalizable dialog generation approach that adapts multi-turn reasoning to generate responses by taking current conversation session context as a document and current query as 'question' they separate the single memory used for document comprehension into different groups for speaker-specific topic and opinion embedding.
Outcome: Experiments on Japanese 10-sentence (5-round) conversation modeling show that multi-turn reasoning can produce more diverse and acceptable responses than state-of-the-art single-turn and non-reasoning baselines.
