Despite the recent success of deep-learning based semantic segmentation, deploying a pre-trained road scene segmenter to city whose images are not presented in training set would achieve satisfactory performance due dataset biases. Instead collecting large number annotated each interest train or refine segmenter, we propose an unsupervised learning approach adapt segmenters across different cities. By utilizing Google Street View and its time-machine feature, can collect unannotated for at...

Background Multiple-choice item (MCI) assessments are burdensome for instructors to develop. Artificial intelligence (AI, e.g., ChatGPT) can streamline the process without sacrificing quality. The quality of AI-generated MCIs and human experts is comparable. However, whether equally good across various domain- task-specific prompts remains be determined. Therefore, we ask AI generate high-quality assess learning outcomes from a psychology textbook chapter reading. Objective In an exploratory...

This work addresses continuous space-time video super-resolution (C-STVSR) that aims to up-scale an input both spatially and temporally by any scaling factors. One key challenge of C-STVSR is propagate information among the frames. To this end, we introduce a local implicit neural function. It has striking feature learning forward motion for continuum pixels. We motivate use from perspective individual trajectories, as opposed mixture trajectories with backward motion. ease interpolation,...

As an intense laser pulse propagates through underdense plasma, the strong ponderomotive force pushes away electrons and produces a trailing plasma bubble. In meantime itself undergoes extreme nonlinear evolution that results in spectral broadening toward long-wavelength side. By experiment we demonstrate this process can be utilized to generate ultrashort midinfrared pulses with energy three orders of magnitude larger than produced by crystal-based optics. The infrared is encapsulated...
