Latest Patents

Jinwoo Choi's latest patents include innovative techniques that address challenges in video domain adaptation. One of his notable patents is titled "Self-supervised cross-video temporal difference learning for unsupervised domain adaptation." This method provides a way to adapt a source domain video to a target domain video using a Cross Video Temporal Difference (CVTD) loss. The process involves annotating the source domain video while leaving the target domain video unannotated. The CVTD loss is computed by quantizing clips from both videos and sampling them to derive meaningful insights.

Another significant patent is "Shuffle, attend, and adapt: video domain adaptation by clip order prediction and clip attention alignment." This method focuses on human action recognition by utilizing annotated source data and unannotated target data. It employs an attention mechanism to identify and align discriminative clips, thereby learning spatial-background invariant human action representations through a self-supervised clip order prediction loss.
