Performing linear regression on a set of data points
Implementing a decision tree algorithm
Understanding the Answer
Let's break down why this is correct
The log-sum-exp function is used to compute softmax probabilities, turning raw scores into a smooth probability distribution for each class. Other options are incorrect because A common misconception is that log-sum-exp gives the exact maximum value; Linear regression fits a straight line to data.
