Random Forest and KNN is fun
K-nearest neighbors (KNN) is a machine learning algorithm that classifies data points based on their closest neighbors. Random forest is an ensemble learning method that constructs multiple decision trees during training and outputs the class that is the mode of the classes of the individual trees. It works by constructing many decision trees during training and outputting the class that is the mode of the individual trees' classes. Random forest introduces randomness when building trees by using bootstrap samples of the data and randomly selecting a subset of features to consider when looking for the best split. This helps to decrease variance and helps prevent overfitting.

Integers are whole numbers that can be positive, negative, or zero. They include numbers like -5, 0, 1, 5, and do not have decimal or fractional parts. The set of all integers is represented by Z and includes positive numbers greater than zero, negative numbers less than zero, and zero, which is neither positive nor negative but is a whole number. Examples of integers are any numbers in the set Z, such as -5, 0, 1, 5, 8, 97, and 3,043.
Alcantara_Interview.pptx
The document discusses different types of interviews that can be used for research purposes. It defines interviews as verbal conversations between two people where the interviewer's objective is to collect relevant information. There are several types of interviews described - structured interviews follow a strict set of pre-written questions, unstructured interviews give the interviewer freedom over the questions, and focused interviews aim to get in-depth information on specific topics. Other interview types covered are non-directive, clinical, and telephone interviews. The document also outlines the typical interview process, including planning, preparing questions, pilot testing, conducting the interview, recording responses, and analyzing the collected data.
Alcantara_Prime&Composite.pptx
The document discusses prime and composite numbers. Prime numbers are integers that are only divisible by 1 and themselves, with examples including 7, 11, and 13. Composite numbers have more than two factors, like 8 which is divisible by 1, 2, 4, and 8. The document provides examples of prime and composite numbers and notes that these categories only apply to positive integers, not negative numbers.
basic-stats.pptx
This document discusses elementary statistics and probability. It introduces common statistical terms and concepts like level of measurement, nominal and ordinal scales, interval and ratio scales. It also discusses sampling and different sampling techniques used in statistics. Key terms introduced include statistics, data analysis, level of measurement, nominal scale, ordinal scale, interval scale, and ratio scale. Examples are provided for each level of measurement.
Convenience Sampling.pptx
This document discusses convenience sampling, which is a type of non-probability sampling where samples are gathered from populations based on their accessibility and availability. Convenience sampling does not give all individuals in the population an equal chance of being selected. It is a simple, low-cost method where the first available subjects can be used without additional screening. While it is easy to implement, convenience samples can be biased and not generalizable to the overall population due to the non-random selection process.
