Latest Patents

One of Leong's latest patents is titled "NLP-guided video thin-slicing for automated scoring of non-cognitive, behavioral performance tasks." This invention utilizes a video of a subject performing a task to generate a transcript via an automatic speech recognition (ASR) system. The transcript is then segmented into text segments, which are tokenized. A transformer model extracts a textual representation for each segment, and a fused representation is created by combining these textual representations with corresponding visual and audio features from the video. A sparse attention machine learning model selects the optimal slice of the video based on these fused representations, which can then be analyzed by machine learning models to evaluate the subject's performance.

Another significant patent is the "Platform for automated scoring of scientific visual models." This system processes drawings in a modeling prototype by accessing a data structure associated with a visual model. It analyzes the visual model to extract construct-relevant features and generates a statistical model using a multidimensional scoring rubric. The automated scoring is determined based on these features and the statistical model, and the results can be displayed, transmitted, or printed.
