Hi, I am looking for a way to get confusion matrix for binary classification. I was able to get confusion matrix for multiclass classification using this [1]. But I could not find a proper way to get confusion matrix in similar class available for binary classification [2]. Later I found this class [3] which corresponds to my requirement but I am not sure about the way I should use that class to get evaluation metrics for binary classification. e.g. Given the constructor BinaryConfusionMatrixImpl(BinaryLabelCounter count, BinaryLabelCounter totalCount), from where I can get this count and totalCount? Appreciate any help on this.
