## Tensor

### Convolutional Neural Networks

The expected data table format is a 3D tensor column with the image data (a 3D tensor is a list of matrices, one for each input image channel (red, green blue) or in this case since MNIST is black and white, a list with a single matrix for the black and white pixel values) followed by the output vector column.

Data tables can contain vector, matrices, 3D tensors, index lists and weighted index lists.

The type of each column can be as simple as a single number, and as complex as a 3D tensor (a cube of numbers).
