对话状态跟踪挑战与贝叶斯方法

The Dialog State Tracking Challenge with Bayesian Approach

University of Hamburg(汉堡大学)

Quan Nguyen

摘要:

生成模型是解决对话状态跟踪问题的最常用的方法之一,它能够以显式的方式对对话假设进行建模。在这种贝叶斯网络模型中,最重要的任务是通过学习并将训练数据反映到以网络状态为条件的用户动作的概率分布中来构建最可靠的用户模型。本文提供了一个全面的学习过程中的贝叶斯框架,强调最先进的理论分析的期望最大化学习算法。

英文摘要:

Generative model has been one of the most common approaches for solving the Dialog State Tracking Problem with the capabilities to model the dialog hypotheses in an explicit manner. The most important task in such Bayesian networks models is constructing the most reliable user models by learning and reflecting the training data into the probability distribution of user actions conditional on networks states. This paper provides an overall picture of the learning process in a Bayesian framework with an emphasize on the state-of-the-art theoretical analyses of the Expectation Maximization learning algorithm.
