Latest Patents

One of Guangsen Wang's latest patents is titled "Systems and methods for an end-to-end evaluation and testing framework for task-oriented dialog systems." This invention provides a software framework designed for evaluating and troubleshooting real-world task-oriented bot systems. The evaluation framework includes a generator that infers dialog acts and entities from bot definitions, generating test cases for the system through model-based paraphrasing. Additionally, it features a simulator for task-oriented dialog user simulation, supporting both regression testing and end-to-end evaluation. The framework also incorporates a remediator to analyze and visualize simulation results, remedy identified issues, and offer actionable suggestions for improving the task-oriented dialog system.

Another significant patent is "Systems and methods for a multilingual speech recognition framework." This invention introduces an Adapt-and-Adjust (A2) mechanism for multilingual speech recognition models, combining adaptation and adjustment methods into an integrated end-to-end training process. This approach aims to improve the models' generalization and mitigate long-tailed issues. The framework utilizes a multilingual language model, mBERT, which is converted into an autoregressive transformer decoder. A cross-attention module is added to the encoder on top of mBERT's self-attention layer to explore the acoustic space alongside the text space. The joint training of the encoder and mBERT decoder effectively bridges the semantic gap between speech and text.
