Human memory storage may be lossy compression and recall may be decompression. Some very rare individuals remember every day of their life in vivid detail, not sure what that means in terms of memory storage. How does consciousness fit into your compression intelligence modeling? The thing about the word compression is that it is bass-ackwards when talking about intelligence. The word describes kind of an external effect, instead of an internal reconfiguration/re-representation. Also there is a difference between a goal of achieving maximum compression verses a goal of achieving a high efficiency data description. Max compression implies hacks, kludges and a large decompressor. Here is a simple example of human memory compression/decompression - When you think of space, air or emptiness like driving across Kansas, looking at the moon, or waiting idly over a period of time, do you store the emptiness and redundantness or does it get compressed out? The trip across Kansas you remember the starting point, rest stops, and the end, not the full duration. It's a natural compression. In fact I'd say this is a partially lossless compression though more lossy... maybe it is incidental but it is still there.
