Abstract

We present an entropy conservation principle applicable to either discrete or continuous variables which provides a useful tool for aggregating observations. The associated method of modality grouping transforms a variable Z 1 into a new variable Z 2 such that the mutual information I(Z 2,Y) between Y, a variable of interest, and Z 2 is equal to I(Z 1,Y).
