jidt's Introduction

Java Information Dynamics Toolkit (JIDT)

JIDT provides a stand-alone, open-source code Java implementation (also usable in Matlab, Octave, Python, R, Julia and Clojure) of information-theoretic measures of distributed computation in complex systems: i.e. information storage, transfer and modification.

JIDT includes implementations:

principally for the measures transfer entropy, mutual information, and their conditional variants, as well as active information storage, entropy, etc;
for both discrete and continuous-valued data;
using various types of estimators (e.g. Kraskov-Stögbauer-Grassberger estimators, box-kernel estimation, linear-Gaussian), as described in full at ImplementedMeasures.

JIDT is easy to use:

It ships with a GUI application -- the AutoAnalyser, see picture below -- to facilitate point-and-click analysis, as well as code template generation for more complex analysis.
We provide short video lectures and corresponding slides in a (beta) Course on how to understand using information-theoretic tools to analyse complex systems, and to implement such analysis with JIDT.

JIDT is distributed under the GNU GPL v3 license (or later).

Getting started

Download and Installation is very easy!
1. Quick start: take a git clone (then build via AntScripts) OR download the latest v1.6.1 full distribution (suitable for all platforms) and see the readme.txt file therein.
Documentation including: the paper describing JIDT at arXiv:1408.3270 (distributed with the toolkit), a (beta) Course including short video lectures and a shorter Tutorial, and Javadocs (v1.6.1 here);
Demos are included with the full distribution, including a GUI app for automatic analysis and code generation (see picture below), simple java demos and cellular automata (CA) demos.
1. These Java tools can easily be used in Matlab/Octave, Python, R, Julia and Clojure! (click on each language here for examples)

Analytic Chi Square distribution have wrong "actual value"

The actualValue field is populated by the computed info theoretic value * 
observations, which is fine for a chiSquare distribution, but is not correct 
for TE or MI clients. (Should be just the computed info theoretic value)

Alter MutualInfoCalculatorMultiVariate significance calculations to specify which variable should be reordered

The ChannelCalculators talk about reordering the source variable to evaluate 
the statistical significance, but the 
MutualInfoCalculatorMultiVariate.computeAverageLocalOfObservations(int[] 
newOrdering) method reorders the second variable (which is now the 
destination). This is because it used to have source variable as the second 
argument.

Should reorganise this code so that it follows a consistent interpretation 
(reordering the source variable - the first variable). This will necessitate 
shuffling the arguments around in the Kraskov calculators. They are currently 
consistent (MI gives right result, TE calculator uses the variables in the 
correct order) but I want this finalised.

Replace org.octave.Matrix calls with our own class

Conversion between native octave types and java types is not always working 
correctly in octaveToJavaDoubleArray, octaveToJavaDoubleMatrix, 
octaveToJavaIntArray and octaveToJavaIntMatrix, as identified by Christoph 
Hartmann:

"The bug seems to be in the octaveToJavaDoubleMatrix.m. Whenever the Java 
Matrix is created there with javaObject('org.octave.Matrix',...), it sometimes 
returns an int matrix and sometimes a double matrix. Whenever an int-matrix is 
returned, the .asDoubleMatrix() returns null, which leads to the NullPointer 
Exception. I suspect that this happens because the int-constructor is called 
instead of the double-constructor [2], but different forms of casting the 
values to double or the dimensions to int did not help."

The issue appears to be that octave is somehow not identifying the correct 
method signature in org.octave.Matrix. This bug is repeatable in 
octave/example6, which should load an array of doubles from a file, but somehow 
these are read into octave as integers. It is unclear why.

Solution appears to be to make the typing explicit in the method signatures, 
rather than to let octave decide it for us,

Kernel estimator to prob density function properly

the kernel estimator at the moment is effectively using a probability distribution function rather than density function. This is because it is not correcting for the kernel width. The probability value returned should be divided by the kernel width so that it properly represents a density, and the entropies calculated will then be differential entropies.

KSG calculators to add noise in by default

I had left noise addition out by default so that results were repeatable. But 
with a small value of noise this should still be ok. Adding noise will stop us 
from getting crazy errors when systems converge to fixed attractors and we get 
lots of the same data points coming in. This has happened with Rose I think in 
2014, and on email to Sussex in 2015.
Consider this to make sure I'm not missing any good reason not to do it; then 
do it.

Mixed Kraskov estimator should have option for adding noise to continuous variable

Mixed continuous-discrete Kraskov estimator should have an option to adding noise to the continuous variable

Linear Gaussian TE estimator should probe Exception from CholeskyDecomposition

Following discussion between Wibral, Priesemann and Lizier today, we realised 
that it would be more appropriate for the TE calculator to return specific 
results in different cases where an exception is raised by the Cholesky 
Decomposition (non-positive definite matrices).
These cases are:
1. Non-positive definite covariance matrix between dest past and source -> 
return zero
2. Non-positive definite covariance matrix between dest past and next value -> 
return zero
3. Non-positive definite between all values: a. if others were positive 
definite -> return infinity, else should not come to this point.

Add dynamic exclusion time / Theiler window to Kraskov calculators

This can easily be done for single-time series estimations, by changing the 
code which avoids the same time step to avoid multiple time steps around that.
Presumably we should actually alter the psi(N) here too I think, since we don't 
have a full set of N points going into every neighbourhood count then.

To implement this for the ensemble method would be tricky, and I don't think we 
should try this in the first pass.

Add random noise to data in Kraskov calculators

Large numbers of identical data cause problems for the Kraskov estimator (since 
they violate its underlying assumptions).
Kraskov's toolkit MILCA adds in a small amount of random noise to address this.

We should add a property to do this to all Kraskov calculators.
This has been done for the Kraskov MI calculator in r305, but we still need to 
add it to conditional MI calculators and check that it works ok for TE and AIS.

Kraskov calculators to ensure they use actual k in joint space than assumed k

At the moment, our Kraskov calculators assume that they have k values within 
epsilon in the full joint space. Where the distribution is composed of delta 
functions (i.e. somewhat discretised) this won't be the case - there could be 
many more than k. As such, it may be more correct to use the actual k for each 
observation in contributing digamma(k) - 1/k, then averaging, rather than 
assume the parameter k.
This may add significantly to the runtime however so we could either:
- just issue a warning were this to occur, or
- track the actual k values in an array, then compute digamma(k) - 1/k once for 
each distinct value and add these in to the result.
