On the minimax risk of dictionary learning
WebMinmax (sometimes Minimax, MM or saddle point) is a decision rule used in artificial intelligence, decision theory, game theory, statistics, and philosophy for minimizing the possible loss for a worst case (maximum loss) scenario.When dealing with gains, it is referred to as "maximin" – to maximize the minimum gain. Originally formulated for …
