Deep learning + minibatch training

The NeuralNet package has been completely rewritten from the ground up!

We're excited to announce many new features, including:

• Deep learning support: build your networks with an arbitrary number of layers
• Minibatch inference/training: execute your net on grouped data of any size you wish
• Performance: HUGE performance gains, especially with minibatch training. Some test have seen a 50x speed improvement
• Improved API

Independent activations

Activation functions may now be set for hidden and output layers independently.
