Altered and manipulated multimedia is increasingly present widely distributed via social media platforms. Advanced video manipulation tools enable the generation of highly realistic-looking altered multimedia. While many methods have been presented to detect manipulations, most them fail when evaluated with data outside datasets used in research environments. In order address this problem, Deepfake Detection Challenge (DFDC) provides a large dataset videos containing realistic manipulations...

Our ability to plan and make effective decisions depends on an accurate mental model of the environment. While learning generally requires novel external observations, people can also improve their understanding by reasoning about past experiences. In this work, we examine whether counterfactual simulation enhances in environments where planning is straightforward but encoding new information challenging. Across two studies, participants navigated gridworlds, avoid hazardous tiles. Some were...
