Title: Innovations of Stephen R. Lawrence

Introduction

Stephen R. Lawrence is a notable inventor based in New York, NY (US). He has made significant contributions to the field of information retrieval and music classification, holding a total of 6 patents. His work utilizes advanced machine-learning techniques to enhance the way we interact with audio data and retrieve information.

Latest Patents

One of his latest patents is focused on extracting and classifying data in music from an audio bitstream. This innovative method employs machine-learning techniques, particularly Support Vector Machines in combination with a neural network. It processes a unique machine-learning enabled representation of the audio bitstream. The method allows a classifying machine to autonomously detect characteristics of a piece of music, such as the artist or genre, and classify it accordingly. The process includes transforming the digital time-domain representation of music into a frequency-domain representation, dividing that frequency data into time slices, and compressing it into frequency bands to form multiple learning representations of each song. These representations are then processed by a group of Support Vector Machines and a neural network, both trained to distinguish among a given set of characteristics for classification.

Another significant patent involves a method for retrieving answers from an information retrieval system. This invention automates the learning of phrase features for classifying questions into different types. It generates candidate query transformations from a training set of question/answer pairs and evaluates these transformations on information retrieval systems. During runtime, questions are transformed into a set of queries, and re-ranking is performed on the retrieved documents.
