Background
I am a graduate student and a researcher. I do not like to rely on commercial products due to cost and also because I feel more comfortable in using and extending existing tools based on languages such as Java, Python, C#, and R.
Right now I want to establish a base line of classic neural networks before I extend my work into deep learning. I consider the following essential for my baseline: ANNs for ARMA such as: Simple recurrent networks (SRN), Elman-Jordan (RNN); Time Delay Neural Networks (TDNN); and Gamma Memories.
Problem
I need a single open source tool that can do Simple Recurrent Networks, Elman - Jordan, Time Delay Neural Networks, and Gamma Memories. This will allow me to establish my baseline and then extend my work into deep learning.
Attempts
Unfortunately, the only two tools I found so far are both commercial. One is MATLAB Neural Networks Toolbox and the other is a package called Neurosolutions. I found a very similar post here, but the original poster was too general and I didn't see any good answers for my issue. My needs are very specific to the above problem.
I deeply thank everyone for reading this question and appreciate your kind assistance.
