A confusion matrix is a fundamental evaluation metric in machine learning, used for assessing the performance of classification algorithms. It is a table that summarizes the number of correct and incorrect predictions made by a model, broken down by class. Statement 1 is correct because the confusion matrix is used for evaluation, and Statement 2 is also correct because it records the predicted vs actual outcomes, providing insights into model performance.
There is a circular park of diameter 65 m as shown in the following figure, where AB is a diameter. An entry gate is to be constructed at a point P on the boundary of the park such that distance of P from A is 35 m more than the distance of P from B. Find distance of point P from A and B respectively.
