Latest Patents

Xiang Wu's latest patents include "Systems and methods for weighted quantization." This patent addresses the quantization of a database using a novel loss or quantization error function. The function applies a weight to the error measurement of quantized elements, which corresponds to the data points in the database. The weight is determined based on the magnitude of an inner product between the respective data points and a query. This innovative approach prioritizes error reduction for higher-ranked pairings, providing solutions to traditional quantization problems.

Another significant patent is "Multiscale quantization for fast similarity search." This patent describes systems and methods that utilize a multiscale quantization model to create a quantized dataset. The model performs vector quantization on a first dataset and generates a residual dataset based on the results. It applies a rotation matrix to the residual dataset, allowing for the reparameterization of each rotated residual into direction and scale components. This method enhances the efficiency of similarity searches in large datasets.
