anomaly_transformer_pytorch's Issues

Dataprocess

How should I process my data?The function "get_data" has not been defined.

Incorrect prior_association() ?

It seems the method prior_association() can not back propagate gradient to train Ws, or maybe I misunderstood?

def prior_association(self):
p = torch.from_numpy(
np.abs(np.indices((self.N, self.N))[0] - np.indices((self.N, self.N))[1])
)
gaussian = torch.normal(p.float(), self.sigma[:, 0].abs())

according to paper, is this the right way?
gaussian = 1 / math.sqrt(2 * math.pi) / self.sigma * torch.exp(- 0.5 * (p / self.sigma).pow(2))

Hi, I have a question !

Your research is very impressive and wonderful. However, I have one question while reading the paper.

in this paper, For the maximize phase, we optimize the series-association to enlarge the association discrepancy. This process forces the series-association to pay more attention to the non-adjacent horizon.

Maximize phases seem to focus more on series-association on adjacent horizon, but why is this non-adjacent horizon?

In my opinion, if the sigma of the prior association is much less than 1, the series association will only look at more adjacent areas.

Thank you
