Dimitris Papailiopoulos says information theory was not designed to address algorithmic phenomena in AI and instead analyzes limits on communication, storage, retrieval, and compression

The exchange began with Jiaxin Wen claiming the framework cannot explain AI.

It's very disappointing that information theory cannot explain AI at all.

Information theory was not built to explain algorithmic phenomena. It's a beautiful framework for arguing about the limits of information: what can be communicated, stored, retrieved, compressed etc. Most attempts I've seen at forcing IT onto AI feel like trying to make coffee with a katana. Magnificent instrument but wrong job :)

@DimitrisPapail ai folks somehow are still frequently using description length or proposing new variants

@DimitrisPapail I am always impressed by their papers but feel disappointed when using those metrics to explain AI
