Inference in AI

The inference is finding a conclusion or result based on any data, events, and any information. Usually, there will be a set of conditions and the conclusion is made, which satisfies all the given conditions are true. The conclusion is made according to the inference rules. Any artificial intelligence agent or an intelligent system uses the inference engine to find a better result or output. The work of the inference engine is to analyze the fact and figures based on all circumstances. After the analysis, the machine concludes this fact and gives it to the agent. The agent uses this conclusion for further processing and decision-making. Intelligent systems will generate new logic from existing ones based on the facts.

This exercise uses the function MapColor and predicates In(x,y), Borders(x,y), and Country(x), whose arguments are geographical regions, along with constant symbols for various regions. In each of the following we give an English sentence and a number of candidate logical expressions. For each of the logical expressions, state whether it (1) correctly expresses the English sentence; (2) is syntactically invalid and therefore meaningless; or (3) is syntactically valid but does not express the meaning of the English sentence.1.

Suppose that we are using PDDL to describe facts and actions in a certain world called JUNGLE.

Justify your answer.

From "Horses are animals" it follows that "The head of a horse is the head of an animal." Demonstrate that this inference is valid by carrying out the following steps: a. Translate the premise and the conclusion into the language of first-order logic. Use three predicates: Headof (h, x) (meaning "h is the head of x"), Horse (x), and Animal (x). b. Negate the conclusion, and convert the premise and the negated conclusion into conjunctive normal form. c. Use resolution to show that the conclusion follows from the premise.
