So I managed to train using the cifar dataset.

How do i test the model using the test dataset?

Hi Rahul,

The test performance is computed line 69 of test/train.lua. The computePerf
function takes in a split ('train' or 'test') and computes performance of
the model on that split.

@gravity1989 I have a question. Is the Laplacian matrix obtained from all the training data and fixed during training? If a single sample is a graph structured data(say represented as a weighted matrix), how should I do?

I am not sure if its fixed or otherwise. I have just about managed to runt
he code.

The .mat file is loaded and modifications could be happening which is
invisible to me.

Yes, the Laplacian matrix is fixed during training. It is first estimated
from the training data, and then its eigenvectors are used to define a
Graph Fourier Transform which is a generalization of the regular Fourier
transform. Pointwise multiplication in this new "frequency" space
corresponds to a convolution on the graph.
