I'm starting to learn neural network and I'd like to know if it's possible to do the following:

I have text data, like this:

apple, 1.23, 5.26, fruit
carrot, 4.56, 7.25, vegetable
banana, 1.34, 6.77, fruit
orange, 1.96, 6.88, fruit
potato, 7.23, 2.33, vegetable

and so on...

apple, carrot... are the names of the images... next two column values are features extracted... and the last column is the text i wanted to get displayed when the particular image is selected....

just the values in the last column are different, but all fitting a simple pattern.

I'd like to use this as training data, and then input to the network a question like:

if apple is selected fruit should be displayed?

Can that be done in matlab? Please could someone reply? I can't even enter the data properly... if without using neural networks also please do someone reply....

Why bother with a network? Why not just have a look-up table,

T = {'apple', 'fruit'; 'carrot', 'vegetable'; 'banana', 'fruit'}
name = tolower( input('Enter name of item', 's') );
[tf, idx] = ismember(name, T(:,1));
if tf
  fprintf('%s is a kind of %s\n', name, T{idx, 2});
else
  fprintf('I do not know what a "%s" is\n', name);
end
