NAME

       mlpack_perceptron - perceptron

SYNOPSIS

        mlpack_perceptron [-m unknown] [-l string] [-n int] [-T string] [-t string] [-V bool] [-o string] [-M unknown] [-P string] [-h -v]

DESCRIPTION

       This  program  implements  a  perceptron,  which  is  a  single level neural network.  The
       perceptron makes its predictions based on a linear predictor function combining a  set  of
       weights  with  the feature vector. The perceptron learning rule is able to converge, given
       enough iterations (specified using the ’--max_iterations (-n)'  parameter),  if  the  data
       supplied  is  linearly  separable.  The  perceptron is parameterized by a matrix of weight
       vectors that denote the numerical weights of the neural network.

       This program allows loading a perceptron from a model (via the  ’--input_model_file  (-m)'
       parameter)  or  training  a perceptron given training data (via the '--training_file (-t)'
       parameter), or both those things at once.  In addition, this program allows classification
       on a test dataset (via the ’--test_file (-T)' parameter) and the classification results on
       the test set may be  saved  with  the  '--predictions_file  (-P)'  output  parameter.  The
       perceptron model may be saved with the '--output_model_file (-M)' output parameter.

       Note:  the  following  parameter  is  deprecated  and  will  be  removed  in mlpack 4.0.0:
       '--output_file (-o)'.  Use '--predictions_file (-P)' instead of '--output_file (-o)'.

       The training data given with the '--training_file (-t)' option may have  class  labels  as
       its  last  dimension (so, if the training data is in CSV format, labels should be the last
       column). Alternately, the '--labels_file (-l)' parameter may be used to specify a separate
       matrix of labels.

       All  these options make it easy to train a perceptron, and then re-use that perceptron for
       later classification. The invocation below trains a perceptron on 'training_data.csv' with
       labels 'training_labels.csv', and saves the model to 'perceptron_model.bin'.

       $  mlpack_perceptron  --training_file  training_data.csv --labels_file training_labels.csv
       --output_model_file perceptron_model.bin

       Then, this model can be re-used for classification on the test data  ’test_data.csv'.  The
       example below does precisely that, saving the predicted classes to 'predictions.csv'.

       $  mlpack_perceptron  --input_model_file  perceptron_model.bin  --test_file  test_data.csv
       --predictions_file predictions.csv

       Note that all of the options may be specified at once: predictions may be calculated right
       after  training a model, and model training can occur even if an existing perceptron model
       is passed with the '--input_model_file (-m)' parameter. However, note that the  number  of
       classes  and  the  dimensionality  of all data must match. So you cannot pass a perceptron
       model trained on 2 classes and then re-train with a 4-class dataset. Similarly, attempting
       classification  on  a  3-dimensional  dataset with a perceptron that has been trained on 8
       dimensions will cause an error.
