What lightweight neural networks are there for Java?

Question

I have a specific problem of having to decide in a fuzzy way between various outputs from a given set of metrics. It's a perfect candidate for neural network approaches.

I've used Joone in the past with success but I'm a little scared of its 2MB jar file for something that in my mind can be done in far less code than that.

Of course the "Roll your own" approach would do it, but I'd rather be using something with more eyeballs on it than just mine.

What do you suggest I do?

Answer 1

You may get some mileage out of the book Introduction to Neural Networks with Java and its downloadable examples

Answer 2

I've used Joone in the past with success but I'm a little scared of its 2MB jar file for something that in my mind can be done in far less code than that.

What do you mean "scared of"? Why are you scared of it? Are you embedding it in a device with limit memory or other resources? Do you think they have hidden malicious code somewhere in the 2MB jar?

If you have used it in the past with success, unless there is some specific constraint or other basis for your fear that you haven't mentioned, I would suggest you just use it again. Absent specific constraints, 2MB is nothing in this day and age.

There is also the Encog Project for Java:
