Mar 22, 2021 at 19:16 | comment | added | Erwan | @dwkd what you're describing in the comment is a two-stages method: stage 1 is deterministic and stage 2 is statistical. In the case of your problem you can indeed do something similar: 1) if the instance is known then predict the label from the training data (deterministic, as I said in the answer) 2) if the instance is unknown then predict from a model trained from the training set (in this case there might be errors, exactly like a doctor could make a mistake). Note that if the ML setting is chosen to be conservative, it can take care of both (1) and (2) because it would always predict ... | |
Mar 22, 2021 at 18:59 | comment | added | dwkd | I was expecting this answer but was hoping there's some sort of hybrid deterministic + statistcal algorithm, just as we humans use in the real world. For example, a doctor applies a pure deterministic approach when triaging a patient but quickly starts augmenting it with statistics when new facts that he hasn't encountered before emerge. | |
