What are two components of an expert system?

An expert system generally consists of four components: a knowledge base, the search or inference system, a knowledge acquisition system, and the user interface or communication system.

The strategy used to search through the rule base is called the inference engine. Two strategies are commonly used: forward chaining and backward chaining (see Figure 10-1). In forward chaining the inference engine begins with the information entered by the user and searches the rule base to arrive at a conclusion.

Q. What is an inference engine and what is the difference between forward chaining and backward chaining?

Forward chaining as the name suggests, start from the known facts and move forward by applying inference rules to extract more data, and it continues until it reaches to the goal, whereas backward chaining starts from the goal, move backward by using inference rules to determine the facts that satisfy the goal.

Q. What is inference mechanism?

Q. What is the future of AI and ML?

With a humongous amount of data becoming more available today, Machine Learning is starting to move to the cloud. Data Scientists will no longer explicitly custom code or manage infrastructure. A.I. and ML will help the systems to scale for them, generate new models on the go and deliver faster and accurate results.

Q. Can artificial intelligence be dangerous?

If AI surpasses humanity in general intelligence and becomes “superintelligent”, then it could become difficult or impossible for humans to control. Just as the fate of the mountain gorilla depends on human goodwill, so might the fate of humanity depend on the actions of a future machine superintelligence.
