Unico GUI Decision Tree generation error and filter coefficients.
Hello,
I am trying to develop an audio classification problem using Unico GUI as software to create a decision tree based on certain features and characteristics for an MLC. However, when I try to generate the decision tree, It doesnt seem to create nothing and instead on the .txt file the only thing that appears is the following:
No found the arff file.[load_arff]
No sample. [CART]
This must be an error because I am generating the arff file and generating the decision tree right after and the arff file is being generated properly but the decision tree. I know the arff file is working properly because I can load it in external tools such us weka. I wonder if the MEMs evaluation kit has to be connected to the computer in order for it to generate de decision tree or if I am simply doing something wrong.
Another issue is that the features selected for a filter are not recognized in Weka, or at least, they don't influence the decision tree classification when using that arff file on Weka and I don't know if this is an issue with weka or I am supposed to generate the decision tree with Unico in order for the filters to be recognized (but as I said, the decision tree is not generated properly on Unico). As for the filter coefficients, I also have the question of how they are supposed to be computed because I have tried multiple things (even expressing them in half precision floating point format as it says on the guide for MLC) but nothings seems to work. As useful information I must add that I am computing the filter coefficients with MATLAB using the butter function.
I would appreciate if somebody can give me any type of insight on the topic. Thanks.
