Abstract: Methods and systems for semantic encoding by a user equipment (UE) are configured for determining an expected power consumption for encoding video data that includes semantic features, the semantic features representing a meaning of information represented in video frames of the video data; encoding one or more video frames of the video data using a selected a semantic representation of one or more video frames of the video data, the semantic representation being selected based on the expected power consumption that is determined; and transmitting the encoded video data including the semantic representation.

Abstract: Methods, systems, and computer programs for distributed processing of a matrix data structure is disclosed. In one aspect, the method can include obtaining a first matrix data structure (DS), segmenting the obtained matrix DS into a set of M different matrix DS portions, segmenting each of the different M matrix DS portions into respective sets of K matrix DS sub-portions, for each of the respective sets of K matrix DS sub-portions: generating an obfuscation matrix having the same dimensions as each of the K matrix DS sub-portions, and generating, by one or more computers, an obfuscated representation of each respective set of K matrix DS sub-portions that includes (i) the K matrix DS sub-portions and (ii) the obfuscation matrix, and transmitting data representing each (of the N) obfuscated representation of the (K) matrix DS sub-portions of the respective sets of M matrix DS portions to a different computer for processing.
