If pruning a subtree, we would remove the subtree completely with method (b). However, with method (a), if pruning a rule, we may remove any precondition of it. The latter is less restrictive.

In this assignment, you will be using a regression tree to
analyze some data about contract negotiations.
Athlete Contract Negotiations (regression tree). Casey Deesel is a sports agent negotiating a contract for Titus Johnston, an athlete in the National Football League (NFL). An important aspect of any NFL contract is the amount of guaranteed money over the life of the contract. Casey has gathered data on 506 NFL athletes who have recently signed new contracts. Each observation (NFL athlete) includes...

Decision Tree Analysis Construct a decision tree. You are going to open a private gym in Chantilly, Virginia. Your idea is to provide fitness service for women only, but including men in not out of the realm of possibility. The cost and time to have the building owner build-out the facility is one month and $80,000. If you do the work yourself, the owner of the building will give you break on your rent but it will take you four...

For this assignment you will build a decision tree (sometimes referred to as a flowchart) that would help an unidentified tissue to be identified. In other words, if you are looking at a picture of an unidentified tissue, what are the questions that you would ask yourself to identify the tissue? View the video to see how this process should proceed. At the end of this assignment you should have produced a decision tree that one of your peers could...

For this assignment you will build a decision tree (sometimes referred to as a flowchart) that would help to determine whether a nerve fibers were part of the sympathetic or parasympathetic division of the ANS. At the end of this assignment you should have produced a decision tree that you or one of your peers could use to properly distinguish between the two divisions of the ANS. You can use morphological or functional characteristics to narrow down identification, however, characteristics...

The school has an option to either implement a screening tool (alt) or do nothing (alt2). Below for an elementary school to address are the possible outcomes: Correctly identifying a bullied student means the concern can be addressed by obtaining the If the test identifies a student as bullied but the student is not...

Which is riskier? Why?
2. (20pts) You have the option to choose between investments A and B represented in the following decision tree 0.5 $10000 0.2$5000 0.3 $2000 0.6 0.1 0.3 $13000 $5000 $500 a. (6pts) Assuming a risk-neutral attitude, what is the best decision? b. (5pts) Assume a risk-averse attitude with a utility function U(x) -In(x). What is the best decision?

Assume that you have built a dense B+-tree index on SSN, and the B+-tree's leaf nodes contain record ids pointing to data records in data file. Assume 10-byte long. Assume also that you built the tree by using bulk loading so that the nodes at each level were filled up as much as possible. 4. a. b. How many levels does the resulting tree have? For each level of the tree, how many nodes are at that level? How many...

Investment Timing Option: Decision-Tree Analysis The Karns Oil Company is deciding whether to drill for oil on a tract of land that the company owns. The company estimates the project would cost $11 million today. Karns estimates that, once drilled, the oil will generate positive net cash flows of $5.39 million a year at the end of each of the next 4 years. Although the company is fairly confident about its cash flow forecast, in 2 years it will have...

Problem 1. 1. Draw the decision tree for the merge-sort algorithm for the input consisting of 3 numbers: a, b,c. 2. Draw the 4 top levels of the decision tree for the merge-sort algorithm for the input consisting of 4 numbers: a, b, c, d 3. How may leaves does this tree have? 4. How many levels does this tree have? 5. What is the number of comparisons needed to sort these 4 numbers by the merge-sort algorithm in the...

(b) You are given the AVL Tree in the figure below. Assume that the nodes are sorted in alphabetical order. E J B D K A F L H Draw the resulting BST after node E is removed. To construct the new BST replace node E with an appropriate node from the left subtree of E. Do not rebalance the resulting tree. Label each node in the resulting tree with its balance factor. (e) Now rebalance the tree from the...
