Latest Patents

One of his latest patents is titled "Model selection for production system via automated online experiments." This invention includes an automated online experimentation mechanism that can perform model selection from a large pool of models with a relatively small number of online experiments. The probability distribution of the metric of interest, which contains the model uncertainty, is derived from a Bayesian surrogate model trained using historical logs. The disclosed techniques can identify a superior model by sequentially selecting and deploying a list of models from the candidate set that balances exploration and exploitation.

Another notable patent is the "Dynamic correlated topic model." This system implements a dynamic correlated topic model (DCTM) to model the evolution of topic popularity, topic representation, and topic correlation within a set of documents or other datasets over time. The DCTM processes the set by analyzing words of the documents, identifying word clusters representing the topics, and computing various distributions for each topic using continuous processes. This captures the popularity, representation, and correlation with other topics across the period of time.
