Minimum description lengthAlso known as the minimum description length principle, it means that among multiple hypotheses for storing data, the hypothesis that can produce the greatest data compression effect is the best.

The minimum description length principle is a result of the formalization of Occam's razor, introduced by Jorma Rissanen in 1978. Its main idea is that any regularity in any given data set can be used for compression, that is, when describing the data, fewer symbols can be used than required compared to describing the data word by word.
