Given the Prediction results of a model, and the cost-benefit matrix, what Score threshold value should be used for classification (classify the instance to Y or N) in the model to achieve the maximum profit. The score in the table indicates the probability (generated by the model) of each instance belongs to category Positive Calculation process and formulars must be included in your answer! Table 1 Prediction results from the model Instance True class | Score 1 Positive 0.965 2 Positive 0.451 3 Positive 0.850 4 Positive 0.699 5 Negative 0.432 6 Negative 0.399 7 Negative 0.597 8 Negative 0.110 Table 2 Cost-benefit matrix True class Positive Negative Prediction from Y $20 -$5 the model N -$1 -$1
