Pedro Martinez Mediano 446ac4ae59 Merge branch 'master' into gpu 2017-11-21 14:58:15 +00:00
jlizier 0e27dbcbc2 Fixed default value of dynamic exclusion window in Kernel MI calculator to be 0. Technically it is zero (because dynCorrExcl boolean is set to false, but gets reported as 100 because the integer value of dynCorrExclTime was not set to 0 itself) 2017-09-02 20:18:36 +10:00
Pedro Martinez Mediano ed71502bc2 Remove old cudaLibraryLoad code and unnecessary dependencies. 2017-08-31 16:22:12 +01:00
jlizier b2e3ae1ca0 Added missing getProperty() method to Conditional TE calculator Kraskov 2017-08-23 00:19:09 +10:00
jlizier 0e40ec2401 Initialising conditional TE calculator to have one conditional dimension by default instead of none. Also fixing the way the conditional parameters are printed via getProperty() when they are null. 2017-08-23 00:18:41 +10:00
jlizier 4db008ce33 For Conditional MI calculators (sontinuous), adding setObservations and addObservations method signatures which take univariate arrays (only work if initialised dimensionalities are univariate) into the interface, and the common base class. This is in preparation for the CMI AutoAnalyser 2017-08-22 21:26:44 +10:00
jlizier 4d6fc1a572 Updated Kozachenko-Leonenko multivariate Entropy calculator to implement EntropyCalculator interface, in preparation for Entropy AutoAnalyser 2017-08-21 14:56:20 +10:00
jlizier 086bee5945 Making continuous MultiInfoCalculator classes implement the InfoMeasureCalculatorContinuous interface. For the interfaces, this means removing methods where duplicated. For implementing classes, this means adding the missing methods. 2017-08-18 23:42:43 +10:00
jlizier 057f17e338 Making continuous PredictiveInfoCalculator classes implement the InfoMeasureCalculatorContinuous interface. For the interfaces, this means removing methods where duplicated. And fixed the common implementing class to have the missing getProperty method. 2017-08-18 23:11:37 +10:00
jlizier 65c7cd99cc Making continuous EntropyCalculator and EntropyCalculatorMultiVariate classes implement the InfoMeasureCalculatorContinuous interface. For the interfaces, this means removing methods where duplicated. Also added NUM_DIMENSIONS property to EntropyCalculatorMultiVariate interface, so that these calculators can have an initialise() method which takes no parameters. Fixed all implementing classes to have any methods that they were missing. 2017-08-18 20:18:29 +10:00
jlizier d6bd16546b Added new interface InfoMeasureCalculatorContinuous to capture common methods for continuous calculators. Also adapted most continuous calculators to implement this, which involved in many cases removing duplicate definitions of these methods in the interfaces for these measures. For ConditionalMI calculator, this meant we needed to add an implementation of the zero-argument initialise() call also. Still need to do MultiInfo, PredictiveInfo and Entropy in future, as they're missing a few methods. 2017-08-18 16:54:55 +10:00
jlizier 3e64fd28bd Altering various continuous calculators to implement the EmpiricalNullDistributionComputer interface (where they're already implementing computeSignificance() etc.). Also altered the EmpiricalNullDistributionComputer methods to throw Exceptions, since the continuous calculators generally do this (and doesn't harm the discrete ones). Also involved implementing the methods in ConditionalMIMultiVariateCommon by selecting to permute the first variable by default. 2017-08-18 15:31:27 +10:00
jlizier d77a9f274e Added interface ChannelCalculator for MutualInfoCalculatorMultiVariate; this should have always been there but not all calculators implemented the univariate methods. It previously only implemented ChannelCalculatorMultiVariate. Added those methods into MutualInfoMultiVariateCommon, which provides the base implementation for all required calculators, so all are now taken care of. This means MI and TE can both be fully used in one interface with the set/addObservations methods. 2017-08-18 13:54:10 +10:00
jlizier ea40f48bbc Adding new methods computePValueForGivenEstimate() and computeEstimateForGivenPValue to AnalyticMeasurementDistribution and implementing in ChiSquareMeasurementDistribution. Involves importing (and refactoring) a significantly larger chunk of commons.maths3 classes (and updating existing ones to latest 3.6.1 version for consistency). Also addresses issue #23 in changing the actual value of the ChiSquareMeasurementDistribution to be that of the information theoretic measurement rather than 2*N times it (which was the value that is actually chi squared distributed), which also necessitates changes to the Discrete and Gaussian calculators computeSignificance() methods. 2017-06-14 11:09:01 +10:00
