Latest Patents

Among his latest inventions, Chuang Gan developed a patent for self-supervised speech recognition. This invention involves a process where one or more computer processors obtain an initial subnetwork aimed at a target sparsity and utilize a pruning mask derived from a pre-trained self-supervised learning speech model. The processors fine-tune the subnetwork by zeroing out specific masked weights and training a new subnetwork from this adjusted base. The final step involves pruning weights of the lowest magnitude to meet the target sparsity, allowing the finetuned subnetwork to classify audio segments effectively.

Another notable patent focuses on an interpretable visualization system for graph neural networks. This system employs a trained graph neural network model to classify input instances and utilizes a gradient-based saliency matrix to enhance the interpretability of its predictions. By incorporating user input, the system can adapt and modify the graph neural network model to improve classification accuracy.
