WebNov 17, 2024 · Binary classification is a subset of classification problems, where we only have two possible labels. Generally speaking, a yes/no question or a setting with 0-1 outcome can be modeled as a … WebBinary classification accuracy metrics quantify the two types of correct predictions and two types of errors. Typical metrics are accuracy (ACC), precision, recall, false positive rate, F1-measure. Each metric measures a different aspect of the predictive model. Accuracy (ACC) measures the fraction of correct predictions.
