Question
Hello Sir
I want to ask you about some problems which have faced by Artificial Intelligence.
  I am working on a project in which I deal with huge amounts of data.I am trying to make some relation between some (9) inputs and one output. Firstly I applied Fuzzy Logic concept and defined 16 output bins(fuzzifying output) in which I divided output to some parts and then I applied Normal distribution Fuzzy membership function and calculated the Fuzzy possibility of each input belonging to output.
   But the problem is in the huge number of data which makes calculations difficult in Excel.I have tried NCSS and some other statistical software but they don't work as I want. I would be pleased if you introduce me a software which be able to do Fuzzy calculations.
    The second problem is in Neural Networks.I have tried some statistical softwares but they don't give me the desired outputs.For example SPSS 16 Neural Network give me the good results in forecasting output but only for training data and it exclude test data set and say: Test data set have coefficients which does not occur in train data set.
    Also statistica NN does not give good results with applied data.Some other NN softwares does not have compatibility with Excel.
   So please introduce me a NN software which is  compatible with Excel and has different options to do and gives good forecasting results.
                   Thank you.

Answer
Hello javad,

in both cases i recommend MATLAB. However, you can't just use an 'off-the-shelf' program and expect it to work in exactly the way you want it to, especially in research fields such as AI. If you get involved with matlab, i'd suggest you read the Neural Network and The Fuzzy logic toolboxes, and off course have a sound grasp of the theory of ANNs and FL.
