Title: Weizhi Xu: Innovator in Retrieval and Signal Processing Technologies

Introduction

Weizhi Xu is a prominent inventor based in Shanghai, China. He has made significant contributions to the fields of retrieval apparatus and signal processing. With a total of 2 patents, his work focuses on enhancing the efficiency of data retrieval and signal processing methods.

Latest Patents

Weizhi Xu's latest patents include a retrieval apparatus, methods, and storage medium. This innovative retrieval apparatus comprises a memory and a processor. The processor is designed to acquire a retrieval request that includes a query vector. Based on the query vector, it generates and executes a first access request corresponding to the first memory, utilizing a first graph index and an index node in the candidate pool. The apparatus determines and processes the data acquired by the first access request, ensuring that there is no redundant data in the previous storage pool. The results are stored in a result pool, and the data output corresponds to the candidate pool, which excludes unreachable index nodes. This retrieval apparatus significantly improves the efficiency of the data reading process and enhances the overall retrieval process.

Another notable patent by Weizhi Xu is related to a signal processing apparatus, signal processing method, output apparatus, output method, and a program for learning and restoring signals with sparse coefficients. This apparatus includes a learning unit that learns a variety of base signals, which become sparse in their coefficients for each feature of the signals. This allows the signals to be represented through a linear operation of the multiple base signals.
