i have a matrix of data that i want to feed in my neural network. The raw data has a shape of (896000,6). As i need one dimension to be 128 elements i have two coices: (7000, 128, 6) or (7000, 6, 128). I know that the first dimension is the batch dimension. My question is, what is the correct shape for my Keras model?
Is there a rule of thumb to these kind of problems?
Thanks in advance.
