Title: Innovations of Inventor Xiang Yu

Introduction

Xiang Yu is a prominent inventor based in Berlin, Germany. He has made significant contributions to the field of document processing and character recognition. With a total of 5 patents, his work focuses on enhancing the efficiency and accuracy of data extraction from documents.

Latest Patents

Xiang Yu's latest patents include innovative systems and processes for aligning weakly-annotated data to recognized characters in documents. One of his notable inventions is a method for aligning annotation data to recognized characters. This method involves receiving annotation words and character recognition tokens, followed by a search algorithm that aligns the annotation words to the tokens in a stepwise manner. The process calculates the cost of each alignment and generates a bounding box enclosing the tokens in the selected full set for output to a target application.

Another significant patent is related to self-attentive key-value extraction. This invention provides systems and methods for the automated identification of key-value pairs in documents. The process begins with receiving a document containing readable text, which is then processed to determine a plurality of tokens. By using pairs of vectors, attention scores are calculated and normalized to identify connected tokens within the document.
