Brad Wootton de44f67d46 Final commit for Brad's thesis. All remaining TODO comments are real TODOs. Support for larger alphabets has been added for entropy and mutual information, lightly tested. The old misleading 'alphabet size' has refactored to 'base'. 2024-12-24 20:40:51 +10:00
Brad Wootton ac8326aecf Discrete entropy is complete I think. Maybe a few more things moved around. No tests yet. 2024-08-22 13:52:19 +10:00
Joseph Lizier a9b6b3e77c Adding property to set random seed for noise addition to EntropyMultiVariate estimators (mimicing that for MI/CMI estimators), extending the fix for issue #99 to Entropy estimators 2024-04-20 18:52:10 +10:00
Joseph Lizier 3d1f3fec86 Gathering common functionality of EntropyMultiVariate estimators into a Common class. Adds some new functionality (e.g. addObservations() for Gaussian and Kernel) 2024-04-20 17:57:38 +10:00
Joseph Lizier 2a18cd0e74 Adding property to allow used to set random seed for noise addition to data in MI, CMI and wrapped estimators. Closes issue #99 2024-04-16 14:08:04 +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
