3. Experiment 2 ‐ Recovering from degeneration

How to run?

Building

1. git checkout recovering-from-degeneration.
2. Open dynamic-neural-field-degeneration folder and run build.bat.
3. The recovering-from-degeneration.exe will be located in dynamic-neural-field-degeneration\dynamic-neural-field-degeneration\build\x64-release\Release\.

Setting up the experiment

You will only need to build the project once, afterwards if you want to change the experiment parameters, you just have to change the experiment_parameters.json file. In this file, you will have the following options (hopefully, the names of the variables are pretty self-explanatory):

{
  "experiment_parameters": {
    "numberOfTrials": 100,
    "startingExternalStimulus": 0,
    "decisionTolerance": 2,
    "isDataSavingOn": false,
    "isVisualizationOn": true,
    "isDebugModeOn": false
  },

  "degeneration_parameters": {
    "#comment_type": "WEIGHTS_DEACTIVATE, WEIGHTS_RANDOMIZE, WEIGHTS_REDUCE, NEURONS_DEACTIVATE",
    "experimentType": "WEIGHTS_DEACTIVATE",
    "#comment_total_number": "720*280 = 201600 or 720 or 280",
    "totalNumberOfElementsToDegenerate": 201600,
    "#comment_fieldToDegenerate": "perceptual, output",
    "fieldToDegenerate": "perceptual",

    "initialPercentageOfDegeneration": 80,
    "targetPercentageOfDegeneration": 100,
    "#comment_incrementOfDegenerationInPercentage": "0.1389, 0.278, 0.5",
    "incrementOfDegenerationInPercentage": 0.5
  },
  "relearning_parameters": {
    "#comment_type": "ALL_CASES, ONLY_DEGENERATED_CASES",
    "relearningType": "ONLY_DEGENERATED_CASES",
    "learningRate": 0.01,
    "numberOfEpochs": 1,
    "maxAmountOfDemonstrations": 200,
    "#comment_update": "When deactivating neurons, updateAllWeights should be set to true",
    "updateAllWeights": false
  }
}

Where to look for generated data

At dynamic-neural-field-degeneration\dynamic-neural-field-degeneration\data\results you will find .txt files with the amount of relearning cycles needed to recover lost behaviour as degeneration increases for each condition.

Additionally, you will find a analysis-files folder with some .R scripts used to generate some plots (plots folder) and some statistical analysis (analysis folder).
