Hey, Nicola thanks for reporting this... The way bootstrap resampling works will not be affected by very small segment level differences because for the wins, losses, ties
count we will average across several segments and we will do this several times across different splits.
If two systems have the exact same translations I can ensure you that you will have x_win = 0.5
and y_win = 0.5
or at least something really close to that which is not statistically significant.
Btw the root of this problem comes from the layerwise normalization we do which can be affected by the batch_size
. In practice, it's not desirable but negligible as you said.

why do not apply a smooth decision for the ties count?
Something like
if subsample_x_scr > subsample_y_scr + epsilon:
win_count[0] += 1
elif subsample_y_scr > subsample_x_scr + epsilon:
win_count[1] += 1
else:
win_count[2] += 1
with a reasonably small value for epsilon
from comet.
that's a reasonable idea for the system-level score. I'll fix it along with the other issues you reported
from comet.
@nicolabertoldi thanks for the issues! I believe everything is working properly now. Please tell me if not
