Interpreting ROC Curve and ROC AUC for Classification Evaluation

WebMay 15, 2016 · FP. In FP, a function takes inputs and produces output with the guarantee that the same inputs will yield the same outputs. In order to do this, a function must always have parameters for the values it operates on and cannot rely on state. Ie, if a function relies on state, and that state changes, the output of the function could be different. WebJun 24, 2024 · How to Calculate FN, FP, TN, and TP Values? As discussed earlier, FN: The False-negative value for a class will be the sum of values of corresponding rows except for the TP value. FP: The False-positive value for a class will be the sum of values of the corresponding column except for the TP value. phil stanforth https://steveneufeld.com
