  • Kaggle competition attempt. Not successful

    Greetings everybody,

    here I want to preserve for future usage my code which I've used to train model for one of Kagglecompetitions:

    1 package org.deeplearning4j.examples.convolution;


    3 import;

    4 import;

    5 import org.deeplearning4j.datasets.iterator.BaseDatasetIterator;

    6 import org.deeplearning4j.datasets.iterator.FloatsDataSetIterator;

    8 import org.deeplearning4j.datasets.iterator.impl.MnistDataSetIterator;

  • How to create learning set for neural network in deeplearning4j

    Hello everybody,

    today I want to document one simple feature of Deeplearning4j library. Recently I had an assignment to feed into neural network for Deeplearning4j.

    If your learning set is not big ( later I'll explain what big means ) then you can put all your data into INDArray and then based on that you can create DataSet. Take a look at fragments of

    1 // list off input values, 4 training samples with data for 2

    2 // input-neurons each

    3 INDArray input = Nd4j.zeros(4, 2);


    5 // correspondending list with expected output values, 4 training samples

    6 // with data for 2 output-neurons each

    7 INDArray labels = Nd4j. … more
