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.

Abstract: In the present disclosure, several techniques are proposed to estimate the worst-case crosstalk noise and use it for bit-loading and SRA calculations so that fluctuating crosstalk when PET mode is enabled does not lead to system instability. One of the proposed techniques involves strategically placing some marker tones in the transmitters of the affecting lines. The noise floor may be inferred by interpolating the noise observed on these marker tones (tones that are always-on) and applying to the entire frequency band on the victim line. Another proposed technique involves periodically transmitting a set of marker symbols (fully loaded OFDM symbols), so that a victim channel can estimate the SNRs in a worst case crosstalk scenario.
