I remember when I was a little kid and I wanted a special cake for my birthday. My mom would ask what cake I wanted and I would tell her that I wanted a cake to look like something or someone. It didn't look like it at all but it was nice enough to eat. But now, it is really possible to make a food look like something or someone. Thanks to advances in science, we can now turn anything from eggs to bugs into a tasty snack. If we can think it, we can make it, and we can eat it. I cho

music similar to the United States. On Christmas Day the people who live in the outback send Christmas greetings to each other over the radio network. Australians also decorate their houses with bunches of Christmas Bush. This is a native Australian tree with small green leaves and cream colored flowers. In summer the flowers turn a deep shiny red over a period of

Unit 7: Trees - Assignment Part I. Basic Computations 1. Using the following tree, name two vertices that are considered the following. Explain in your own words how you know: (a) parent-child (2 points). Answer: 202 - 401 Explanation: the parent of a vertex is the vertex connected to it on the path to the root, 202 is the parent and 401 is the child (b) sibling nodes (2 points): Answer: 301, 302, 303 Explanation: If two vertices are children of the same parent, then these

incorporated into the post. Update 28-May-2015: Thanks to Dan Steinberg (yes, the CART expert!) for the suggested updates to the CART section which have now been added. 1. C4.5 What does it do? C4.5 constructs a classifier in the form of a decision tree. In order to do this, C4.5 is given a set of data representing things that are already classified. Wait, what’s a classifier? A classifier is a tool in data mining that takes a bunch of data representing things we want to classify and attempts to

Question 1) Describe a B-Tree implementation When databases are used with a pointer s there is an indexing technique called a B-Tree. Within this B-Tree structure all references to the data within as well as that can be accessed. That is why data can be deleted easier and faster. At the bottom of the B-Tree is what is referred to as a node and the root is located on the top. The only way I can explain this, is by using a figure we all see every day. Look at a tree upside down, that is what

Matthew Hendrickson Tree Lab Questions 1. Recursive algorithms work well for trees because recursion allows for storing areas that have been traversed on the system stack, so that all avenues can be explored. Similar to the maze example from the chapter on recursion. Recursion also works well when the same steps have to be repeated on different parts of a data structure and is often simpler and more elegant than iteration with a loop. The same way an array is continuously broken and half and
