About the decay factor $\alpha_i$

[albertcity]

Hi,
In the paper, it is said that the $\alpha_i$ is different when fusing global information $Z_{G_i}$ (in Eq.10).
However, I found that $\alpha_i$'s are actually the same (in the reweighting.py):

        pre_features = pre_features * args.presave_ratio + cfeatures * (1 - args.presave_ratio)
        pre_weight1 = pre_weight1 * args.presave_ratio + weight * (1 - args.presave_ratio)

Have I missed anything?
Tks.
