Online education is rapidly expanding in response to rising demand for higher and continuing education, but many online students struggle to achieve their educational goals. Several behavioral science interventions have shown promise in raising student persistence and completion rates in a handful of courses, but evidence of their effectiveness across diverse educational contexts is limited. In this study, we test a set of established interventions over 2.

Article Synopsis
- The proposed model enhances a pulsed time-of-flight (TOF) camera by allowing for flexible exposure profiles, unlike traditional phase-modulated TOF cameras.
- It employs a generative probabilistic model to link imaging conditions with camera responses, enhancing depth, albedo, and ambient light intensity estimation at video frame rates.
- The new two-path model also accounts for multipath effects efficiently, while a physically accurate simulation provides realistic benchmarks for understanding these phenomena.
