Title: Innovations of Alexander Haojan Liu

Introduction

Alexander Haojan Liu is an accomplished inventor based in Malden, MA (US). He has made significant contributions to the field of speech recognition technology. His innovative work has led to the development of a unique patent that enhances the efficiency of speech models.

Latest Patents

Liu holds a patent for a groundbreaking method in self-supervised speech recognition. This patent involves a process where one or more computer processors obtain an initial subnetwork at a target sparsity and an initial pruning mask from a pre-trained self-supervised learning (SSL) speech model. The processors then finetune the initial subnetwork by zeroing out masked weights specified by the initial pruning mask. Following this, they train a new subnetwork from the zeroed-out subnetwork and prune weights of the lowest magnitude to meet the target sparsity. Ultimately, the finetuned subnetwork is used to classify audio segments effectively.
