Latest Patents

One of Jianxiang Chang's latest patents is titled "Feature pruning and algorithm selection for machine learning." This invention provides systems, methods, and apparatuses for machine learning. In some implementations, a pre-processing system identifies special features in an input dataset and generates pruned datasets based on these features. The system maps each pruned dataset to predictions and selectively removes values associated with special features from the input dataset based on the mapping. In other implementations, the pre-processing system maps feature sets in an input dataset to multiple predictions according to various machine learning algorithms. It evaluates the performance of each mapping and selects the most effective algorithm for training the machine learning model.

Another significant patent is "Large pose facial recognition based on 3D facial model." This method involves generating a captured facial object and pose from an image. It also includes obtaining a base facial object and pose from a base image. The method generates base pose angles and captured pose angles, selects base images using these angles, and compares selected base images to captured images to establish a match output.
