Explain node impurity further Mr. Ballings,
There is no concrete definition of node impurity in your book or one that is very useful on google. Could you explain exactly what node
impurity is and how it pertains to decision trees/random forests?
Answers and follow-up questions Answer or follow-up question 1
Node impurity is defined in the decision tree section (see Gini impurity). It is also explained in the random forest section as the mean
descrease in Gini.
