As shown in Algorithm 1, it displays the overall process of our baseline, which does not consider the different impacts each sample could impose on the model. In other words, our aim is to identify a function, ϕ(g, θ), capable of gauging the contribution of any given generated sample g ∈ G to the current model f. Then, via this scoring mechanism, we can filter and retain the most helpful samples for the model and simultaneously discard those that are useless or even harmful to the model.
