Neural Networks are one of the most breakthrough techniques nowadays. The goal of this project is to perform a radical update to Octave nnet package in order to keep pace with the times. Other open-source projects will be used, like Tensorflow. This will allow to guarantee a continuous updating on neural networks improvement and leading to a greater focus on Octave interface. The tendency to open-researching is strong in the deep learning field, where even the biggest companies release their frameworks and open their code. In this sense, a project on the Neural Networks package, where Octave can coexist with Tensorflow, let us exploit their synergy and reach fast consistent goals.
