SEMANTIC COMPRESSION
First Claim
1. A method performed by a computing device for compressing data, comprising:
- receiving data that represents one or more physical attributes sensed by one or more sensors;
identifying a first region and a second region in the received data by employing at least one pattern or statistical feature;
computing a first utility and a first relevant feature for the first region, and a second utility and a second relevant feature for the second region; and
identifying based on at least the first utility and the second utility a first compression method to apply to the first region and a second compression method to apply to the second region wherein the first and the second compression methods have different compression rates or different feature preservation characteristics.

Abstract
Technology for semantic compression is disclosed. In various embodiments, the technology receives data that represents one or more physical attributes sensed by one or more sensors; employs at least one pattern or statistical feature to identify a first region and a second region in the received data; computes a first utility and a first relevant feature for the first region, and a second utility and a second relevant feature for the second region; and identifies based on at least the first utility and the second utility a first compression method to apply to the first region and a second compression method to apply to the second region wherein the first and the second compression methods have different compression rates, different feature preservation characteristics, or both.
