Machine Learning
the extraction of knowledge from data based on algorithms created from training data
Artificial Intelligence
A scientific field
... [Show More] that focuses on creating machines capable of performing activities that require intelligence when they are done by people.
classifier algorithm
decision process is called classification example: deciding if a moth is a luna moth or an emperor moth
Features
are values that usefully characterize the things we wish to classify
Labeled data
a group of samples that have been tagged with one or more labels
scatter plot
A graph with points plotted to show a possible relationship between two sets of data.
What do machine learning algorithms do?
Find optimal separations.
Decision Boundaries
The region of a problem space in which the output label of a classifier is ambiguous.
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
misclassify
to assign (someone or something) to an incorrect group or category
forest
algorithms that use many decision trees working together to make a prediction
Support Vector Machine
Supervised learning classification tool that seeks a dividing hyperplane for any number of dimensions can be used for regression or classification
Statistics
Collection of methods for planning experiments, obtaining data, organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data.
Artificial Neural Networks (ANNs)
computer systems that are intended to mimic human cognitive functioning
Deep Learning
is part of a broader family of machine learning methods based on learning data representations, as opposed to task-specific algorithms
weak AI or narrow AI
is only intelligent at specific tasks
strong AI
Artificial intelligence with a generalized learning ability, on par with human intelligence.
IBM's Watson
Supercomputer that knows almost anything, but
struggles with real world messy data
Competed on Jeopardy
Google's AlphaGo
a computer program that plays the board game Go
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. [Show Less]
