David Kauchak CS 158 Fall 2016 Admin Assignment 5 back soon write tests for your code variance scaling uses standard deviation for this class Assignment 6 Midterm Course feedback Thanks. Ata . Kaban. Motivation & beginnings. Suppose we have a learning algorithm that is guaranteed with high probability to be slightly better than random guessing – we call this a . weak learner. E.g. if an email contains the work “money” then classify it as spam, otherwise as non-spam. Handshapes that represent people, objects, and descriptions.. Note: You cannot use the classifier without naming the object first.. Types of Classifiers. We will look at the types of classifiers . Size and Shape .

Lesson 8. Bull Markets and Bear Markets. A bear market is a stock market with falling prices over an extended period of time. Selling short can increase gains in a bear market.. A bull market is a stock market with rising prices over an extended time. Buying on margin can increase gains in a bull market.. Lifeng. Yan. 1361158. 1. Ensemble of classifiers.

Tactile ASL is emerging as a variety of ASL that is used by fluent ASL signers who are blind. .
