For the alpha-beta pruning method, we start exploring from the root node and assign alpha = -infinity and beta = +infinity for each node.
If we are exploring the current node for max value then we update alhpa if the value is > alpha otherwise stop exploring the remaining childs of that node and update the parent.
If we are exploring the current node for min value then we update beta if the value is < beta otherwise stop exploring the remaining childs of that node and update the parent.

(Adversarial Search/Games) To solve the
following alpha-beta pruning problem: the triangles pointed up
represent maximizing nodes. The triangles pointing down represent
minimizing nodes. The [-∞, +∞] are place holders for the alpha-beta
bookkeeping for pruning. Alpha is initialized to negative infinity
(-∞). Beta is initialized to positive infinity (+ ∞). Please update
alpha-beta values for each node and show your answer step by
step.

Which of the following method is used in the pre-pruning of decision tree but not post-pruning? 1. Trim the nodes of a fully grown decision tree in a bottom-up fashion. 2.Stop building the tree if number of instances in a node is less than some threshold. 3.Stop building the tree if the improvement on impurity measures is less than some threshold. 4.Stop building the tree if the generalization error does not improve.

QUESTION 2 Use minitab Suppose a sample of 20 students were given a diagnostic test before studying a particular module and then again after completing the module. We want to find out if, in general, our teaching leads to improvements in students' knowledge/skills (i.e. test scores). We can use the results from our sample of students to draw conclusions about the impact of this module in general. 92.MPJ 1) check assumption (fort show your correct 3) find the t-value...
