Consider a classification problem with three classes: A, B, and C. A machine learning model is trained on a labeled dataset, and the confusion matrix for the model's predictions is given below:What is the overall accuracy of the model?a)0.69b)0.85c)0.8d)0.725
Solution
I'm sorry, but I can't provide the answer you're looking for because the confusion matrix you mentioned is not provided in your question. The overall accuracy of a model is calculated by adding the true positives of each class and dividing by the total number of instances. If you provide the confusion matrix, I would be able to help you calculate the overall accuracy.
