Question

How can I input data into keras? What is the structure? Specifically what is the x_train and y_train if I have more than 2 columns?

This is the data I want to input:

Answer 1

It all depends on your need.

It looks like that you want to predict the winner based on the parameters shown in column A - N. Then you should define input_dim to be 14, and X_train should be an (N,14) numpy array like this:

[
   [9278,  37.9, ...],
   [18594, 36.3, ...],
   ...
]

It seems that your prediction set only contains 2 items ( 2 president candidates LOL), so you should encode the answer Y_train in an (N,2) numpy array like this:

[
   [1, 0],
   [1, 0],
   ...
   [0, 1],
   [0, 1],
   ...
]

where [1,0] indicates that Barack Obama is the winner and vice versa.
