Abstract: Techniques for presence detection are described. In an example, system receives, from a first device connected with a computer network that is associated with a location, a first value of a first parameter associated with a link between the first device and a second device. The system determines, using a first prediction model and the first value, a first likelihood of presence at the location. The first prediction model is configured based at least in part on outputs of a second prediction model that uses a second parameter associated with the computer network. The system determines whether the presence is detected at the location based at least in part on the first likelihood.

Abstract: Many unsupervised domain adaptation (UDA) methods have been proposed to bridge the domain gap by utilizing domain invariant information. Most approaches have chosen depth as such information and achieved remarkable successes. Despite their effectiveness, using depth as domain invariant information in UDA tasks may lead to multiple issues, such as excessively high extraction costs and difficulties in achieving a reliable prediction quality. As a result, we introduce Edge Learning based Domain Adaptation (ELDA), a framework which incorporates edge information into its training process to serve as a type of domain invariant information. Our experiments quantitatively and qualitatively demonstrate that the incorporation of edge information is indeed beneficial and effective, and enables ELDA to outperform the contemporary state-of-the-art methods on two commonly adopted benchmarks for semantic segmentation based UDA tasks.
