Subject: ARTIFICIAL INTELLIGENCE (BT9402) (B1367)Answer the following question:Question #1 what is the goal of AI? Explain the importance of AI in today's world.Answer: The fundamental objectives of AI are: - understanding of perception, reasoning, learning, linguistic and creative processes. The understanding will be useful in creating new intelligent and informative tools for use in different industries and universities. Just as the invention of the internal combustion engine and the development of machines like airplanes led to an unprecedented improvement in the mobility of our species, tools emerging from AI research are already beginning to expand intellectual and creative capabilities human in a way that our predecessors could only dream of. Evolutionary understanding of mechanisms expands the potential and limits of intelligence. The result of this evolution is the development of computer systems capable of performing tasks identified as traits of intelligence. The importance of AI in today's world: AI will affect the lives of most individuals in civilized countries. Leading countries in the development of AI by then, they will emerge as the dominant economic powers of the world. With a combined budget of around a billion dollars, the Japanese are determined to achieve many of their goals, namely producing systems capable of conversing in a natural language, understanding speech and visual scenes, learning and refining their knowledge, make decisions and exhibit other human traits. In the United States, first, there was the formation of a consortium of private companies in 1983 to develop advanced technologies that apply AI.... ... middle of paper ..... .it cannot find a match, so this predicate expression fails and the interpreter returns to the previous one, until it finds a match. Whenever the Prolog interpreter cannot find another match for the leftmost expression in a query, the query cannot be satisfied in any way; he types the word no and stops. Whenever, by going back, it can find a new match for a predicate expression, it resumes its movement from there as it originally did. Importance of backtracking in artificial intelligence The purpose of backtracking is to give a “second chance” to a query, by reviewing previous decisions. Backtracking is very important in artificial intelligence because many artificial intelligence methods use intelligent guesses and following hunches to accomplish a task. Assumptions can lead to erroneous conclusions, so backtracking is a good method to recover.
