Contributor s : Ed Burns and Nicole Laskowski Share this item with your network: Artificial intelligence AI is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning the acquisition of information and rules for using the information , reasoning using rules to reach approximate or definite conclusions and self-correction.
Particular applications of AI include expert systems , speech recognition and machine vision. AI can be categorized as either weak or strong. Virtual personal assistants, such as Apple's Siri, are a form of weak AI. Strong AI, also known as artificial general intelligence, is an AI system with generalized human cognitive abilities. When presented with an unfamiliar task, a strong AI system is able to find a solution without human intervention. Because hardware, software and staffing costs for AI can be expensive, many vendors are including AI components in their standard offerings, as well as access to Artificial Intelligence as a Service AIaaS platforms.
AI as a Service allows individuals and companies to experiment with AI for various business purposes and sample multiple platforms before making a commitment.
While AI tools present a range of new functionality for businesses ,the use of artificial intelligence raises ethical questions. This is because deep learning algorithms, which underpin many of the most advanced AI tools, are only as smart as the data they are given in training.
Because a human selects what data should be used for training an AI program, the potential for human bias is inherent and must be monitored closely. Some industry experts believe that the term artificial intelligence is too closely linked to popular culture, causing the general public to have unrealistic fears about artificial intelligence and improbable expectations about how it will change the workplace and life in general.
Researchers and marketers hope the label augmented intelligence , which has a more neutral connotation, will help people understand that AI will simply improve products and services, not replace the humans that use them. Types of artificial intelligence Arend Hintze, an assistant professor of integrative biology and computer science and engineering at Michigan State University, categorizes AI into four types, from the kind of AI systems that exist today to sentient systems, which do not yet exist.

Deep Blue can identify pieces on the chess board and make predictions, but it has no memory and cannot use past experiences to inform future ones. It analyzes possible moves -- its own and its opponent -- and chooses the most strategic move. Deep Blue and Google's AlphaGO were designed for narrow purposes and cannot easily be applied to another situation.
These AI systems can use past experiences to inform future decisions. Some of the decision-making functions in self-driving cars are designed this way.

Observations inform actions happening in the not-so-distant future, such as a car changing lanes. These observations are not stored permanently.
This psychology term refers to the understanding that others have their own beliefs, desires and intentions that impact the decisions they make. This kind of AI does not yet exist. In this category, AI systems have a sense of self, have consciousness. Machines with self-awareness understand their current state and can use the information to infer what others are feeling.

This type of AI does not yet exist. What's the difference between AI and cognitive computing? Examples of AI technology AI is incorporated into a variety of different types of technology. Here are seven examples. Automation: What makes a system or process function automatically.
For example, robotic process automation RPA can be programmed to perform high-volume, repeatable tasks that humans normally performed. RPA is different from IT automation in that it can adapt to changing circumstances.
Machine learning: The science of getting a computer to act without programming. This technology captures and analyzes visual information using a camera, analog-to-digital conversion and digital signal processing.
It is often compared to human eyesight, but machine vision isn't bound by biology and can be programmed to see through walls, for example. Progress slowed and in , in response to the criticism of Sir James Lighthill  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 ",  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 ,  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. S and British governments to restore funding for academic research. According to Bloomberg's Jack Clark, was a landmark year for artificial intelligence, with the number of software projects that use AI within Google increased from a "sporadic usage" in to more than 2, projects.
Clark also presents factual data indicating that error rates in image processing tasks have fallen significantly since Goals can be explicitly defined, or induced. If the AI is programmed for " reinforcement learning ", goals can be implicitly induced by rewarding some types of behavior or punishing others.

An algorithm is a set of unambiguous instructions that a mechanical computer can execute. A simple example of an algorithm is the following optimal for first player recipe for play at tic-tac-toe :  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. 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;  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.AI in healthcare.
