Sklearn logistic regression auc
Webb11 apr. 2024 · What is sensitivity in machine learning? Sensitivity in machine learning is a measure to determine the performance of a machine learning model. Sensitivity determines how well a machine learning model can predict positive instances. Before we understand the sensitivity in machine learning, we need to understand a few terms. They … Webb17 juni 2024 · I think there are a couple of reasons: Logistic regression does not have a deterministic closed form solution and must be solved iteratively, starting from some …

WebbIf I had to guess, "classification" mostly occurs in machine learning context, where we want to make predictions, whereas "regression" is mostly used in the context of inferential statistics. I would also assume that a lot of logistic-regression-as-classification cases actually use penalized glm, not maximum likelihood (iirc that's actually the ...
