Finding Informative Features - CMU Statistics

Similarly, our uncertainty about the class C, in the absence of any other information, is just the entropy of C: H[C] = X c Pr(C= c)log 2 Pr(C= c) Now suppose we observe the value of the feature X.

Methodological Analysis of Principal Component Analysis ...

Principal component analysis is simply a variable reduction procedure that (typically) results in a relatively small number of components that account for most of the variance in a set of observed variables [3]. In summary, both factor analysis and principal component analysis have important roles to play in social science
