Latest Patents
One of Cuize Han's latest patents is titled "Cold start machine learning based database query retrieval." This invention provides systems and methods to tackle cold-start issues in database keyword searches. The search system generates machine-learned values for new items and queries based on historical signals from existing items and queries. These values serve as input for a ranking model that ranks search results for user queries. The initial values predict user engagement with new item-query pairs, enhancing the visibility of new items to gather user interaction data. As additional user interactions occur, the values are updated using a Bayesian formula.
Another notable patent is "Fast feature selection for search models." This invention outlines a method for selecting a subset of features to train models for search applications. Candidate features are randomly divided into two groups, and a decision tree scan is performed to determine which group performs better based on selection criteria. This binary splitting and scanning process continues until one feature remains, which is then designated as the selected feature for the search model.
