Machine Learning & Artificial Intelligence: Crash Course Computer Science #34

scatter plot

A graph with points plotted to show a possible relationship between two sets of data.

Artificial Intelligence

A scientific field that focuses on creating machines capable of performing activities that require intelligence when they are done by people.

strong AI

Artificial intelligence with a generalized learning ability, on par with human intelligence.

Statistics

Collection of methods for planning experiments, obtaining data, organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data.

What do machine learning algorithms do?

Find optimal separations.

IBM's Watson

Supercomputer that knows almost anything, but struggles with real world messy data Competed on Jeopardy

Support Vector Machine

Supervised learning classification tool that seeks a dividing hyperplane for any number of dimensions can be used for regression or classification

Decision Boundaries

The region of a problem space in which the output label of a classifier is ambiguous.

Google's AlphaGo

a computer program that plays the board game Go

Labeled data

a group of samples that have been tagged with one or more labels

Confusion Matrix

a table that is often used to describe the performance of a classification model (or "classifier") on a set of test data for which the true values are known

reinforcement learning

a type of Machine Learning, and thereby also a branch of Artificial Intelligence. It allows machines and software agents to automatically determine the ideal behaviour within a specific context, in order to maximize its performance.

forest

algorithms that use many decision trees working together to make a prediction

Features

are values that usefully characterize the things we wish to classify

Artificial Neural Networks (ANNs)

computer systems that are intended to mimic human cognitive functioning

classifier algorithm

decision process is called classification example: deciding if a moth is a luna moth or an emperor moth

weak AI or narrow AI

is only intelligent at specific tasks

Deep Learning

is part of a broader family of machine learning methods based on learning data representations, as opposed to task-specific algorithms

Machine Learning

the extraction of knowledge from data based on algorithms created from training data

misclassify

to assign (someone or something) to an incorrect group or category
