You are assuming something about the observer when you assume they will compute "2+2=4". Another observer might compute "2+2=0" for example the group of integers modulo 4 which is a much smaller symbol space. A subset of all lossy compressors compressing on particularly structured data won’t discard any but still compress into smaller strings so the result is a lossless compression, or, a losslesslossyness. In addition, some (if not all?) lossless compressors on particular data, can only expand. What is important then is a Compressor Selection Criteria. ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/T36c83eb0aa31fc55-Md812f63e06fa7100c7cd475a Delivery options: https://agi.topicbox.com/groups/agi/subscription
