Dogs are known to bark and bite.
When any animal barks, it always noisy.
The Hound is a dog.
Conclusion the hounds are noisy.

For example, the Bionics developed in the 60 's, is based on analogical inference. The invention of the radio submarine was obtained from the Flight of birds, the ups and downs of fish, and the analogy of associa

Although we can pay due attention to the rational selection process, the cognitive approach of the system does not adhere to the rational hypothesis (which is measured by some externality criteria), nor does it neglect the generalized psychological process-quasi-inference (analogical reasoning) and t

Case-based reasoning originates from human cognitive psychology, which belongs to analogical inference method. The basic idea is based on the experience and knowledge acquired by people accustomed to dealing with similar problems in problem solving, and adjusting the differences in the old and new situations, so as to get the solution of new problems and form new cases. The application of CBR has been pa

intelligent system. However, in the past, intelligent systems generally lacked the learning ability. For example, they cannot correct themselves when encountering errors; they do not improve their performance through experience; they do not automatically acquire and discover the required knowledge. Their reasoning is limited to deduction and lacks induction. Therefore, they can only prove existing facts and theorems, rather than discovering new theor

When we wake up, explicit consciousness begins to occupy our brains all day and begins to execute stream-of-consciousness activities such as programs. I'm curious about how this kind of stream-of-consciousness process is, and what is the whereabouts of the stream-of-consciousness.I don't have time to think about it. The information goes from the long memory of the brain and from the sides of the senses to our seven small

1. Inference mode
There are three types of inference models for probabilistic graph models:
causal reasoning/causal reasoning : That is, when you know a cause of an event, we change the estimate of the outcome of the event.
evidential reasoning/Evidence Reasoning : That is, when we know the outcome of the event, we
Clisp is a production-based forward inference engine. It is a very basic thing. Many upper-layer reasoning tasks must be mapped to this inference engine for running.
In principle, clisp (or Jess) can handle reasoning tasks in various fields, as long as the system can provide clisp with special domain rules in this field (in the form of production) and fact information (provided in assertion form ). As a typ
From the perspective of gctexamination, the logic knowledge and Examination Form are limited and focused. Even though there are more than a dozen courses in the software designer examination, as long as you know how to strengthen understanding and use of important knowledge points and examination forms, the examination is easier to find a pass. However, whether it is a software designer or gcttest, if it is purely for the test, it will lose the meaning of the test to a large extent. At the same
