Now we know how to measure disorder. Next we need a metric to measure the reduction of this disorder in our target variable/class given additional information ( features/independent variables) about it.
WebSep 29, 2024 · A little more formally, the entropy of a variable is the “amount of information” contained in the variable. You can think of variable as news from the telegrapher. The news can be anything. It doesn’t have to be 4 …
WebEntropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work.
