Rossum's Universal Robots. The study of mathematical logic led directly to Alan Turing 's theory of computation , which suggested that a machine, by shuffling symbols as simple as "0" and "1", could simulate any conceivable act of mathematical deduction. This insight, that digital computers can simulate any process of formal reasoning, is known as the Church—Turing thesis. Turing proposed that "if a human could not distinguish between responses from a machine and a human, the machine could be considered "intelligent". Marvin Minsky agreed, writing, "within a generation Progress slowed and in , in response to the criticism of Sir James Lighthill [37] and ongoing pressure from the US Congress to fund more productive projects, both the U. The next few years would later be called an " AI winter ", [10] a period when obtaining funding for AI projects was difficult. In the early s, AI research was revived by the commercial success of expert systems , [38] a form of AI program that simulated the knowledge and analytical skills of human experts. By , the market for AI had reached over a billion dollars. At the same time, Japan's fifth generation computer project inspired the U.

We treat robotics and vision not as independently defined problems, but as occurring in the service of achieving, goals. We stress the importance of the task environment in determining the appropriate agent design. Our primary aim is to convey the ideas that have emerged over the past fifty years of Al research and the past two millennia of related work.

We have tried to avoid excessive formal- ity in the presentation of these ideas while retaining precision. We have included pseudocode algorithms to make the key ideas concrete; our pseudocode is described in Appendix B. This book is primarily intended for use in an undergraduate course or course sequence.

The book has 27 chapters, each requiring about a week's worth of lectures, so working through the whole book requires a two-semester sequence.

A one-semester course can use selected chapters to suit the interests of the instructor and students. The book can also be used in a graduate-level course perhaps with the addition of some of the primary sources suggested in the bibliographical notes.

Sample syllabi are available at the book's Web site.

The only prerequisite is familiarity with basic concepts of computer science algorithms, data structures, complexity at a sophomore level. Freshman calculus and linear algebra are useful for some of the topics; the required mathematical back- ground is supplied in Appendix A. A simple example of an algorithm is the following optimal for first player recipe for play at tic-tac-toe : [59] If someone has a "threat" that is, two in a row , take the remaining square.

Otherwise, if a move "forks" to create two threats at once, play that move.

Otherwise, take the center square if it is free. Otherwise, if your opponent has played in a corner, take the opposite corner. Otherwise, take an empty corner if one exists. Otherwise, take any empty square. Many AI algorithms are capable of learning from data; they can enhance themselves by learning new heuristics strategies, or "rules of thumb", that have worked well in the past , or can themselves write other algorithms. Some of the "learners" described below, including Bayesian networks, decision trees, and nearest-neighbor, could theoretically, given infinite data, time, and memory learn to approximate any function , including which combination of mathematical functions would best describe the world.

These learners could therefore, derive all possible knowledge, by considering every possible hypothesis and matching them against the data. In practice, it is almost never possible to consider every possibility, because of the phenomenon of " combinatorial explosion ", where the amount of time needed to solve a problem grows exponentially.

Artificial Intelligence: A Modern Approach

Much of AI research involves figuring out how to identify and avoid considering broad range of possibilities that are unlikely to be beneficial. A second, more general, approach is Bayesian inference : "If the current patient has a fever, adjust the probability they have influenza in such-and-such way".

A fourth approach is harder to intuitively understand, but is inspired by how the brain's machinery works: the artificial neural network approach uses artificial " neurons " that can learn by comparing itself to the desired output and altering the strengths of the connections between its internal neurons to "reinforce" connections that seemed to be useful.

These four main approaches can overlap with each other and with evolutionary systems; for example, neural nets can learn to make inferences, to generalize, and to make analogies. Some systems implicitly or explicitly use multiple of these approaches, alongside many other AI and non-AI algorithms; [63] the best approach is often different depending on the problem.

These inferences can be obvious, such as "since the sun rose every morning for the last 10, days, it will probably rise tomorrow morning as well". Learners also work on the basis of " Occam's razor ": The simplest theory that explains the data is the likeliest. Therefore, to be successful, a learner must be designed such that it prefers simpler theories to complex theories, except in cases where the complex theory is proven substantially better.

The blue line could be an example of overfitting a linear function due to random noise. Settling on a bad, overly complex theory gerrymandered to fit all the past training data is known as overfitting. Many systems attempt to reduce overfitting by rewarding a theory in accordance with how well it fits the data, but penalizing the theory in accordance with how complex the theory is. Stuart J.
