What is AI?
Intelligence: capacity for logic, abstract thought, understanding, self-awareness, communication, learning, emotional knowledge, memory, planning, creativity and problem solving.
Artificial Intelligence: the science and engineering of making intelligent machines, especially intelligent computer programs.

Machine Learning
Type of artificial intelligence (AI) that provides computers with the ability to learn without being explicitly programmed.
Machine learning focuses on the development of computer programs that can teach themselves to grow and change when exposed to new data.
Search through data to look for patterns, uses that data to improve the program's own understanding.
Machine Learning
Supervised learning- algorithms are trained on labelled examples
Unsupervised learning- algorithms operate on unlabelled examples
Semi-supervised learning- combines both labeled and unlabelled
Reinforcement learning- learning by interacting with an environment
Association rule learning- discovering interesting relations in large databases
Deep learning- discover multiple levels of representation with higher-level, more
abstract features defined

Google Translate
Free translation service that provides translations between different languages
Can translate words, sentences and web pages between any combination of supported languages
Looks for patterns in hundreds of millions of documents to help decide on the best translation for you
By detecting patterns in documents that have already been translated by human translators
Google Translate can make intelligent guesses as to what an appropriate translation should be
“On the other hand, if we build an AI agent today and tell it to evolve its utility function, how can we assure that it won’t reason that ‘Humans think it is moral to kill annoying insects, in part because insect brains are so primitive. But human brains are primitive compared to my powers, so it must be moral for me to kill humans.’” - Stuart J. Russell
