Features
StochANNPy provides routines compatible with Scikit-Learn for stochastic learning including:
Bayesian neural networks (currently, only classifier) [1]
Evolutionary neural networks (currently, only classifier)
Monte-Carlo Cross-Validation (currently, only classifier)
NOTE: ENNClassifier, BNNClassifier, MCCVClassifier all passed Scikit-Learn checks test! …well almost. Bayesian learning requires more than 5 samples to explore the weight space, BNNClassifier only pass when increasing the maximum number of iterations (line 280 of the script).
Installation
The recommended way to install StochANNPy is through pip:
pip install stochannpy
Otherwise, download and extract the package, then run:
python setup.py install
Usage
First, import StochANNPy and initialize the classifier:
import numpy as np
from stochannpy import BNNClassifier
clf = BNNClassifier(hidden_layer_sizes = (5,))
Fit the training set:
clf.fit(X_train, y_train)
Predict the test set:
ypred = clf.predict(X_test)
Compute the accuracy:
print(np.mean(ypred == y_test))
