Neurolab is a simple and powerful Neural Network Library for Python.
Contains based neural networks, train algorithms and flexible framework
to create and explore other neural network types.
:Features:
- Pure python + numpy
- API like Neural Network Toolbox (NNT) from MATLAB
- Interface to use train algorithms form scipy.optimize
- Flexible network configurations and learning algorithms. You may change: train, error, initializetion and activation functions
- Unlimited number of neural layers and number of neurons in layers
- Variety of supported types of Artificial Neural Network and learning algorithms
:Example:
>>> import numpy as np
>>> import neurolab as nl
>>> # Create train samples
>>> input = np.random.uniform(-0.5, 0.5, (10, 2))
>>> target = (input[:, 0] + input[:, 1]).reshape(10, 1)
>>> # Create network with 2 inputs, 5 neurons in input layer and 1 in output layer
>>> net = nl.net.newff([[-0.5, 0.5], [-0.5, 0.5]], [5, 1])
>>> # Train process
>>> err = net.train(input, target, show=15)
Epoch: 15; Error: 0.150308402918;
Epoch: 30; Error: 0.072265865089;
Epoch: 45; Error: 0.016931355131;
The goal of learning is reached
>>> # Test
>>> net.sim([[0.2, 0.1]]) # 0.2 + 0.1
array([[ 0.28757596]])

:Install:
Install *neurolab* using setuptools/distribute::
easy_install neurolab
Or pip::
pip install neurolab
Or, if you don't have setuptools/distribute installed,
use the download `link <http://code.google.com/p/neurolab/downloads/list>`_
at right to download the source package,
and install it in the normal fashion: Ungzip and untar the source package,
cd to the new directory, and::
python setup.py install
