please explaing why do we have apperture=-1, in the attention class vasnet_model.py

[VinACE]

def init(self, apperture=-1, ignore_itself=False, input_size=1024, output_size=1024):
self.apperture = apperture

here the apperture is set to -1, and in the forward you are checking,
if self.apperture > 0:
#Set attention to zero to frames further than +/- apperture from the current one
when does these condition appears.

Hi VinACE,
The apperture is not used in this publication/code version. We do use it in our follow up work which has not been published yet.
Basically, the apperture<=0 disables the apperture which is the default config in this code.
