4One of the very good methods to analyze the performance of Logistic Regression is AIC, which is like R-Squared in Linear Regression. Which of the following is true about AIC?

11Regarding splits in Decision Trees what criteria makes a great split?
- AThe best split is one that increases purity of the sub-sets by the greatest amount
- BA good split also creates nodes of similar size or at least does not create very small nodes
- CThe weighted sum of items for each split has the smallest amount.
- DA good gini or enthropy split
12What is a Common issues in Deep Learning and Machine learning?
