jlizier 2b0a5cb943 Updated mixed-continiuous CMI KSG estimator, for the bias correction based on number of continuous variables. This was identified from testing, and aligns with testing so far. 2022-09-05 17:51:49 +10:00

jlizier 2714650cfa Amending Kraskov (KSG) MI estimators to have an experimental method to provide conditional entropy of the first variable given the second. Works by removing the Kozachenko Leonenko entropy of variable 1 from the MI, using the same kNN radii as the MI estimator. Includes Unit tests to provide some initial validation. 2022-06-16 21:29:29 +10:00

Joseph Lizier 1dc2dc8b86 Updating all discrete calculators (except SeparableInfo, since it's outmoded) to have a default empty constructor, with an overloaded initialise method added that provides all relevant properties. Fixes #77, and provides a first step for #66. Also aligned PredictiveInfo and ConditionalTE calculators to use the appropriate super classes. 2019-07-25 14:29:51 +10:00
