Latest Patents

One of his latest patents focuses on fine-tuning large language models (LLMs) using reinforcement learning with search engine feedback. This innovation involves various implementations aimed at enhancing LLMs by utilizing responsive content generated from search engine results. Additionally, a supervision signal can be generated by comparing search engine conditioned LLM output with unconditioned LLM output. This supervision signal is instrumental in training a reward model through reinforcement learning, which can subsequently be used to fine-tune the LLM.

Another notable patent is related to end-to-end streaming keyword spotting. This method detects a hotword by receiving a sequence of input frames that characterize streaming audio captured by a user device. It generates a probability score indicating the presence of a hotword using a memorized neural network. The network comprises sequentially-stacked single value decomposition filter (SVDF) layers, each containing neurons with respective memory components. The method also includes determining whether the probability score meets a hotword detection threshold, initiating a wake-up process on the user device for further processing.
