WebJan 24, 2024 · [MUSIC] Thus far we've talked about precision, recall, optimism, pessimism. All sorts of different aspects. But one of the most surprising things about this whole story is that it's quite easy to navigate from a low precision model to a high precision model from a high recall model to a low recall model, so kind of investigate that spectrum. WebBased on that, recall calculation for this model is: Recall = TruePositives / (TruePositives + FalseNegatives) Recall = 950 / (950 + 50) → Recall = 950 / 1000 → Recall = 0.95 This …
