gomi

Introduction

gomi is a software package for the evaluation of morphological intelligence measures on data. gomi includes all currently available morphological intelligence measures. This includes measures with continuous estimators as well as measures that use a discrete estimator.

The following sections will only provide minimal information about the measures. The goal of this post to provide information about the application of the measures, not an introduction of the measures themselves. For this purpose, please visit the other posts on these pages:

Abstract = {There are numerous examples that show how the exploitation of the body's physical properties can lift the burden of the brain. Examples include grasping, swimming, locomotion, and motion detection. The term Morphological Computation was originally coined to describe processes in the body that would otherwise have to be conducted by the brain. In this paper, we argue for a synergistic perspective, and by that we mean that Morphological Computation is a process which requires a close interaction of body and brain. Based on a model of the sensorimotor loop, we study a new measure of synergistic information and show that it is more reliable in cases in which there is no synergistic information, compared to previous results. Furthermore, we discuss an algorithm that allows the calculation of the measure in non-trivial (non-binary) systems.},

Installation

gomi is written in Go. For the installation of Go, please read the installation documentation provided [here]. Pre-compiled binaries of gomi for Windows, Linux, and macOS are available in the release files [here].

Once Go is installed, gomi can easily be installed using the following commands:

The following two packages are required and might have to be installed manually:

Discrete Measures

MI_W

$\fn_phv&space;\mathrm{MI}_\mathrm{W}&space;=&space;I(W';W|A)\\&space;\hspace*{1.5cm}=&space;\sum_{w',w,a}&space;p(w',w,a)&space;\log_2\frac{pw(w'|w,a)}{p(w'|a)}$

To calculate this measure, we need to estimate the joint distribution $\fn_phv&space;p(w',w,a)$ from which the two conditional distributions can be calculated in the following way:

$\fn_phv&space;p(w,a)&space;=&space;\sum_{w'}p(w',w,a)\\&space;\hspace*{0.5cm}p(w',a)&space;=&space;\sum_{w}p(w',w,a)\\&space;\hspace*{1.15cm}p(a)&space;=&space;\sum_{w',w}p(w',w,a)\\&space;\hspace*{0.1cm}p(w'|w,a)&space;=&space;\frac{p(w',w,a)}{p(w,a)}\\&space;\hspace*{0.65cm}p(w'|a)&space;=&space;\frac{p(w',a)}{p(a)}$

These calculations (which are required for the discrete estimator), are done automatically by gomi. The user only needs to provide the data and some parameters, which are explained next.

Command line parameters

OptionExplanation
-helpWill show command line parameters with explantions.
-vVerbose. If not provided, gomi will be executed silently.
-miString identifier for the morphological intelligence quantification. One example is MI_W. For a full list, please use the help command line option.
-cThe discrete (frequency based) estimators are used by default. If this options is provided, the estimators on continuous data (KSG Estimator and Frenzel-Pompe) are used instead.
-cmContinuous mode. There are two different KSG Estimators for mutual information. For those continuous morphological intelligence quantification which operate with mutual information, the KSG Estimator can be chosen with this command line options. Possible values are 1 and 2.
-sState-dependent results. By default, the averaged results are provided. If this option is given, the results are calculated for each state, i.e., the result is a vector with a value for each row in the original dataset.
-binsThis option is used only for the discrete estimators. It determines the number of bins for each column of the W, S, and A datasets.
-iIteration. This command line option is only used for MI_SY, MI_Wp, and MI_SY_NID. It determines the number of iterations for the iterative scaling algorithm.
-oOutput file. The default value is "out.csv". gomi writes all results to the output file, including a header section that includes the full parameterisation of the calculation.
-wbinsOnly used for discrete measures. In case the world state is given by more than one column in the dataset, this option allows to set the binning for each column.
-abinsOnly used for discrete measures. In case the action state is given by more than one column in the dataset, this option allows to set the binning for each column.
-sbinsOnly used for discrete measures. In case the sensor state is given by more than one column in the dataset, this option allows to set the binning for each column.
-fileThis option should be used if W, S, A are provided in a single file. The columns for W, S, and A are the specified with the -wi, -si, and -ai options (see below).
-wiThe values here specify the column of the file provided with -file that relate to the world state.
-aiThe values here specify the column of the file provided with -file that relate to the action state.
-siThe values here specify the column of the file provided with -file that relate to the sensor state.
-wfileWorld state file. All columns of this file will be considered in the calculations.
-afileAction state file. All columns of this file will be considered in the calculations.
-sfileSensor state file. All columns of this file will be considered in the calculations.
-dfileDomain file. This option will only be used for discrete measures. During discretisation, each column is normalised. For comparability between different files, a domain file can be specified, which provides the minimum and maximum values for the world state, action state, and sensor state data.
-kThis parameter is only used for continuous estimators. It is the parameter used for the k-nearest neighbour estimation of entropies.
-logIf this parameter is provided, gomi will write a JSON file that included all information with respect to calculation, including the full raw and pre-processed data
