Study Notes
-
Artificial intelligence is the ability of systems to perceive, synthesize, and infer information.
-
AI research has tried and discarded many different approaches since its founding, including simulating the brain, modeling human problem solving, formal logic, large databases of knowledge, and imitating animal behavior.
-
The various sub-fields of AI research are centered around particular goals and the use of particular tools.
-
The traditional goals of AI research include reasoning, knowledge representation, planning, learning, natural language processing, perception, and the ability to move and manipulate objects.
-
General intelligence (the ability to solve an arbitrary problem) is among the field's long-term goals.
-
To solve these problems, AI researchers have adapted and integrated a wide range of problem-solving techniques – including search and mathematical optimization, formal logic, artificial neural networks, and methods based on statistics, probability and economics.
-
AI also draws upon computer science, psychology, linguistics, philosophy, and many other fields.
-
AI research was born in the early 1950s at a workshop at Dartmouth College.
-
AI research was heavily funded by the Department of Defense in the 1960s and 1970s.
-
AI research was revived by the commercial success of expert systems in the early 1980s.
-
AI research has been in a state of decline since the late 1980s, but has recently been revived.
-
AI has been struggling to create intelligent machines for many years, but in the past few years, it has made significant progress in solving specific problems.
-
The goal of AI is to simulate or create intelligent machines, and the key problem is to find a way to model and solve reasoning problems.
-
Knowledge representation and knowledge engineering are important tools for solving problems and are becoming more prevalent in AI research.
-
There is a concern that AI is no longer pursuing the original goal of creating versatile, fully intelligent machines, and much of current research is focused on statistical AI.
-
AI is the study of creating machines that can think for themselves.
-
AI research has developed a number of tools to represent specific domains, such as objects, properties, categories and relations between objects; situations, events, states and time; causes and effects; knowledge about knowledge (what we know about what other people know);[54] default reasoning (things that humans assume are true until they are told differently and will remain true even when other facts are changing);
-
Machine learning (ML) is the study of algorithms that improve automatically through experience.
-
In supervised learning, a human labels the input data first, and comes in two main varieties: classification and numerical regression.
-
In reinforcement learning, the agent is rewarded for good responses and punished for bad ones.
-
Symbolic AI used formal syntax to translate the deep structure of sentences into logic. This failed to produce useful applications, due to the intractability of logic[47] and the breadth of commonsense knowledge.
