Encog is an advanced neural network and machine learning framework.

Encog is an advanced neural network and machine learning framework. Encog contains classes to create a wide variety of networks, as well as support classes to normalize and process data for these neural networks. Encog trains using multithreaded resilient propagation. Encog can also make use of a GPU to further speed processing time. A GUI based workbench is also provided to help model and train neural networks. Encog has been in active development since 2008.

Encog is available for Java, .Net and C/C++.

Trained neural network outputs the same results for all evaluation rows

There seems to be no problem when training my network because it converges and falls below 0.01 error. However when I load my trained network, and introduce the evaluation set, it outputs the same results for all the evaluation set rows (the actual…

Why does my trained neural network produce the same output

I have trained my neural network using encog 3.3 with MLP, resilientProp (trial since BackProp's learning rate and momentum is hard to set), 10 inputs (including the ideal value), 1 hidden layer with 7 neurons, 1 output neuron, sigmoid activation,…

Encog Neural Net - How to structure training data?

Every example I've seen for Encog neural nets has involved XOR or something very simple. I have around 10,000 sentences and each word in the sentence has some type of tag. The input layer needs to take 2 inputs, the previous word and the current…
