With , an agent typically cannot guarantee to satisfy its goals, and even trying to maximize the probability of achieving a goal may not be sensible.

Uncertainty - In the context of expert systems, uncertainty refers to a value that cannot be determined during a consultation. Many expert systems can accommodate uncertainty.

Management of Imprecision and : Data and knowledgebases in many typical AI problems, such as reasoning and planning, are often contaminated with various forms of incompleteness.
Can also be used to make decisions where uncertainty occurs (fuzzy control). This is a form of non-Aristotelian logic (see general semantics).
A modeling technique that provides a mathematically sound formalism for representing and reasoning about , imprecision, or unpredictability in our knowledge.
Many otherwise excellent colleagues have objected that nanotechnology might be impractical because of quantum uncertainty.
In AI search, there are computational limits and due to the opponent's move as in two-players games. So it is wise to have search and execution interleaved with each search determining only the next move to be made.
Sophisticated methods for reasoning about uncertainty and for coping with incomplete knowledge have led to more robust diagnostic and planning systems.
In this fragment, start_probability refers to your about which state the HMM is in when your friend first calls you (all you know is that it tends to be rainy on average).
Casti also provides an excellent introduction to the problems inherent in predicting weather, the stock market, and other complex phenomena in his book ``Complexification'' (Harper Collins, 1994) and its predecessor ``Searching for Uncertainty: ...
Knowing statistics in your everyday life will help the average business person make better decisions by allowing them to figure out risk and when all the facts either aren't known or can't be collected.
Although artistic appropriation is often permitted under fair use doctrines, the complexity and ambiguity of these doctrines creates an atmosphere of uncertainty among cultural practitioners.

In other words, big amounts of data and high uncertainty, regarding the way the data is produced. Examples are stock values (Forecasting), loan risk, local weather, pattern (faces) recognition, and data mining.
that there is complete about which is the correct class. It turns out that E has a maximum value in this case.
Thus, the more uncertain the network is, the larger the error E. This is as it should be.
Second, the rules had to reflect the uncertainty called certainty factors which seemed (at the time) to fit well with how doctors assessed the impact of evidence on the diagnosis ' (Russel & Norvig, 2003).
