Weird output of xttrain()(1.#INF00)

[derlozi]

Hi, I'm trying to write a small program to train a network on the iris dataset. (https://archive.ics.uci.edu/ml/datasets/iris). When training, xttrain returns values that are printed as 1.#INF00. I don't know whether the fault is on the library's side or my fault. Another weird thing is that when I run the program in debug-mode, it works just fine. Here is the repository with my code: https://github.com/derlozi/TINN-Iris-Dataset I hope that you can help me.
Thanks in advance!

The iris data set uses floating point inputs and string outputs.

5.0,3.3,1.4,0.2, Iris-setosa ... 5.7,2.8,4.1,1.3, Iris-versicolor ... 6.3,2.9,5.6,1.8, Iris-virginica

Try remapping these strings to three floating point outputs

5.0,3.3,1.4,0.2, 0,0,1 ... 5.7,2.8,4.1,1.3, 0,1,0 ... 6.3,2.9,5.6,1.8, 1,0,0

If you can get the data like that then there shouldn't be need to modify test.c (apart from the input file name, the nips, and the nops, and ofcourse nhid and learning rate to your discretion). Let me know how it goes!

I revisited the project and found the bug, I didn't consider line endings when reading out of a file and some data was not initialized correctly. I fixed it and it now works like a charm.

Thanks for checking back
