ParInfoGain - Computes parallel information gain and gain ratio in Matlab using the Matlab Parallel Computing Toolbox or the Distributed Server (if available)



Information gain is defined as:

InfoGain(Class,Attribute) = H(Class) - H(Class | Attribute)



Gain ratio is defined as:

GainRatio(Class, Attribute) = (H(Class) - H(Class | Attribute)) / H(Attribute).



...where H is the entropy, defined as - sum(i=1 to k) pi log2 pi-ParInfoGain - Computes parallel information gain and gain ratio in Matlab using the Matlab Parallel Computing Toolbox or the Distributed Server (if available)
