This approach assumes that, on average, an expert in DRD2 can generalize better to unseen molecules in the sense that their assessment would be better aligned with the true probability of DRD2 bioactivity. The noise term is added to the oracle score to simulate more realistic scenarios where an expert deviates or fails to perceive the true probability of DRD2 bioactivity for a given molecule. We consider σ ϵ = {0.15, 0.3} as well as the ideal scenario where queries are directly evaluated using the oracle (i.e., ϵ = 0).
