Perception learning rule

This is called the perception learning rule and it has been proven to converge to a solution, for linearly separable problems, in a finite number of iterations. The weight adjustment rule can be restated as... 

Performance is said to be at either a skill-based or a rule-based level when tasks are routine in nature. Skill-based performance involves the smooth, automatic flow of actions without conscious decision points. As such, skill-based performance describes the decisions made by highly trained operators performing familiar tasks. Rule-based performance involves the conscious perception of environmental cues, which trigger the application of rules learned on the basis of experience. As such, rule-based performance corresponds closely to recognition-primed decisions (Klein 1989). The... 

Safety professionals must learn to avoid certain perceptions, certain so-called "rules of thumb," as well as other gobbledygook commonly accepted as fact. We commonly hear, for example, that "some people are accident prone." This statement should never be accepted as fact. The implication is, of course, that accidents just seem to follow some individuals, that no matter what they do they just seem to be plagued with bad luck. In reality, of course, no one is truly accident prone. Workers have accidents simply because they are careless, are indifferent to safety regulations and safe work practices, or are required to work under unsafe conditions. 

The program incorporates the standard expert system methodology, i.e., routines to input the molecule and to perform the perception of features, an inference engine, and a knowledge base of rules that can be used to infer potential toxicological problems. One of the most common problems in expert system technology is the creation and expansion of the database. One of the potential solutions to that problem is the use of machine learning to facilitate that task.
