This document summarizes several key dimensionality reduction algorithms:
1) FOCUS and RELIEF are two of the earliest and most widely cited dimensionality reduction algorithms. FOCUS implements feature selection by preferring consistent hypotheses with few features, while RELIEF ranks features based on distance between instances of the same and different classes.
2) RELIEF was later expanded to handle multi-class problems (RELIEF-F) and incomplete data (RELIEF-D). Liu and Dash also reviewed dimensionality reduction methods and categorized them based on their generation and evaluation procedures.
3) Liu et al. proposed the LVF (Las Vegas Filter) algorithm for feature selection, which uses random search guided by in
This document provides instructions and materials for a lesson on polynomials. Students will work through four stations involving adding, subtracting, and multiplying polynomials, as well as factoring polynomials. They are given example problems to work through at each station. Before leaving, students are directed to study links on adding/subtracting/multiplying polynomials and factoring polynomials to prepare for homework and a quiz the next day. The teacher opens the floor for any last-minute questions about the upcoming assessment.
The attribute that should be tested at the root of the decision tree is the attribute that results in the maximum information gain, or minimum entropy, when used to split the training data. In other words, the attribute that best separates the data according to the target classes. This attribute will create "purer" nodes with respect to the target classes.
The defense was successful in portraying Michael Jackson favorably to the jury in several ways:
1) They dressed Jackson in ornate costumes that conveyed images of purity, innocence, and humility.
2) Jackson was shown entering the courtroom as if on a red carpet, emphasizing his celebrity status.
3) Jackson appeared vulnerable, childlike, and in declining health during the trial, eliciting sympathy from jurors.
4) Defense attorney Tom Mesereau effectively presented a coherent narrative of Jackson as a victim and portrayed Neverland as a place of refuge, undermining the prosecution's arguments.
Este documento analiza el modelo de negocio de YouTube. Explica que YouTube y otros sitios de video online representan un nuevo modelo de negocio para contenidos audiovisuales debido al cambio en los hábitos de consumo causado por las nuevas tecnologías. Describe cómo YouTube aprovecha la participación de los usuarios para mejorar continuamente y atraer una audiencia diferente a la de los medios tradicionales.
