David Monllaó	e83f7b95d5	Fix activation functions support (#163) ... - Backpropagation using the neuron activation functions derivative - instead of hardcoded sigmoid derivative - Added missing activation functions derivatives - Sigmoid forced for the output layer - Updated ThresholdedReLU default threshold to 0 (acts as a ReLU) - Unit tests for derivatives - Unit tests for classifiers using different activation functions - Added missing docs	2018-01-09 11:09:59 +01:00

David Monllaó	de50490154	Neural networks partial training and persistency (#91) ... * Neural networks partial training and persistency * cs fixes * Add partialTrain to nn docs * Test for invalid partial training classes provided	2017-05-23 09:03:05 +02:00
David Monllaó	4af8449b1c	Neural networks improvements (#89) ... * MultilayerPerceptron interface changes - Signature closer to other algorithms - New predict method - Remove desired error - Move maxIterations to constructor * MLP tests for multiple hidden layers and multi-class * Update all MLP-related tests * coding style fixes * Backpropagation included in multilayer-perceptron	2017-05-18 00:07:14 +02:00
David Monllaó	c1b1a5d6ac	Support for multiple training datasets (#38) ... * Multiple training data sets allowed * Tests with multiple training data sets * Updating docs according to #38 Documenting all models which predictions will be based on all training data provided. Some models already supported multiple training data sets.	2017-02-01 19:06:38 +01:00
