Identify whether the task required is supervised or unsupervised learning: Deciding whether to issue a loan to an applicant based on demographic and financial data (with reference to a database of similar data on prior customers). - Supervised - Unsupervised -:- Supervised This is supervised learning, because the database includes whether the loan was approved or not. Identify whether the task required is supervised or unsupervised learning: Printing of custom discount coupons at t...

Longest Common Substring An algorithm that determines the longest common substring that exists in two inputs strings. Binary Search An efficient algorithm for searching a list. The ...

How do you tell if a graph has negative edges? - ANSWER-when fitting graph on a table, if the number of moves decreases the w() from edge to edge, then there is a negative edge; check from 1 to n Why are all pairs Dist(y,z) n^2? - ANSWER-Because it builds a two dim table! What is the run time of bellman ford algorithm? How about if you had to do it for all edges? - ANSWER-O(nm) O(n^2m) Floyd-Warshall run time? - ANSWER-O(n^3) What is the base case for the bellman ford algorithm? - ANSWE...

Asymptotic Analysis - How the run time of a program depends on the size of the problem Exact Analysis - Provides a more specific measure of algorithm efficiency than asymptotic analysis. Divide and Conquer Algorithm - An algorithm that solves a problem recursively by splitting it into a fixed number of smaller non-overlapping subproblems of the same type Greedy Algorithm - An algorithm that follows problem solving heuristic of making optimal choices at each stage. Disadva...

SAE: MATH FINAL EXAM. acute triangle - CORRECT ANSWER a triangle in which all three angles measure less than 90 degrees area - CORRECT ANSWER the amount of surface that a shape covers; measures in square units associative property - CORRECT ANSWER when more than two terms are added together or multiplied together, the order in which the terms are paired does not affect the sum or product. In addition, the sum of three or more addends can be found in any order: a+(b+c)=(a+b)+c. In mult...

What is PCA? (5 key points) Principal Component Analysis is a statistical technique used for dimensionality reduction, crucial when dealing with high-dimensional data in machine learning. It works by transforming original variables into new ones, called principal components, which are linear combinations of the original variables. Key Points: 1. Principal Components: Principal components are the directions in the data that maximize variance. The first principal component captures the most...
