Most everyone who thinks about how to solve problems in a formal way has run across the concepts of deductive and inductive reasoning.

Deductive reasoning , also deductive logic , is the process of reasoning from one or more statements premises to reach a logical conclusion. Deductive reasoning goes in the same direction as that of the conditionals, and links premises with conclusions. If all premises are true, the terms are clear , and the rules of deductive logic are followed, then the conclusion reached is necessarily true. Deductive reasoning "top-down logic" contrasts with inductive reasoning "bottom-up logic" : in deductive reasoning, a conclusion is reached reductively by applying general rules which hold over the entirety of a closed domain of discourse , narrowing the range under consideration until only the conclusion s remains. In deductive reasoning there is no epistemic uncertainty.

Deduction & Induction

Reasoning in artificial intelligence has two important forms, Inductive reasoning, and Deductive reasoning. Both reasoning forms have premises and conclusions, but both reasoning are contradictory to each other.

Following is a list for comparison between inductive and deductive reasoning:. The differences between inductive and deductive can be explained using the below diagram on the basis of arguments:. JavaTpoint offers too many high quality services.

Following is a list for comparison between inductive and deductive reasoning: Deductive reasoning uses available facts, information, or knowledge to deduce a valid conclusion, whereas inductive reasoning involves making a generalization from specific facts, and observations.

Deductive reasoning uses a top-down approach, whereas inductive reasoning uses a bottom-up approach. Deductive reasoning moves from generalized statement to a valid conclusion, whereas Inductive reasoning moves from specific observation to a generalization. In deductive reasoning, the conclusions are certain, whereas, in Inductive reasoning, the conclusions are probabilistic. Deductive arguments can be valid or invalid, which means if premises are true, the conclusion must be true, whereas inductive argument can be strong or weak, which means conclusion may be false even if premises are true.

Deductive reasoning is the form of valid reasoning, to deduce new information or conclusion from known related facts and information. Inductive reasoning arrives at a conclusion by the process of generalization using specific facts or data. Use of inductive reasoning is fast and easy, as we need evidence instead of true facts. We often use it in our daily life.

Deductive reasoning

During the scientific process, deductive reasoning is used to reach a logical true conclusion. Another type of reasoning, inductive, is also used. Often, people confuse deductive reasoning with inductive reasoning, and vice versa. It is important to learn the meaning of each type of reasoning so that proper logic can be identified. Deductive reasoning is a basic form of valid reasoning. Deductive reasoning, or deduction, starts out with a general statement, or hypothesis, and examines the possibilities to reach a specific, logical conclusion, according to California State University.

When assessing the quality of an argument , we ask how well its premises support its conclusion. More specifically, we ask whether the argument is either deductively valid or inductively strong. An argument in which the premises do succeed in guaranteeing the conclusion is called a deductively valid argument. If a valid argument has true premises, then the argument is said also to be sound. All arguments are either valid or invalid, and either sound or unsound; there is no middle ground, such as being somewhat valid. The two premises of this argument would, if true, guarantee the truth of the conclusion. However, we have been given no information that would enable us to decide whether the two premises are both true, so we cannot assess whether the argument is deductively sound.

Reasoning is the process of using existing knowledge to draw conclusions, make predictions, or construct explanations. Three methods of reasoning are the deductive, inductive, and abductive approaches. Deductive reasoning: conclusion guaranteed Deductive reasoning starts with the assertion of a general rule and proceeds from there to a guaranteed specific conclusion. Deductive reasoning moves from the general rule to the specific application: In deductive reasoning, if the original assertions are true, then the conclusion must also be true. For example, math is deductive:. As a matter of fact, formal, symbolic logic uses a language that looks rather like the math equality above, complete with its own operators and syntax. But a deductive syllogism think of it as a plain-English version of a math equality can be expressed in ordinary language:.

Самое место, где толкнуть колечко: богатые туристы и все такое прочее. Как только получит денежки, так и улетит. Беккер почувствовал тошноту. Это какая-то глупая шутка.

Стратмор был поражен до глубины души. Никто никогда не позволял себе говорить с заместителем директора АНБ в таком тоне. - Сьюзан, - проговорил он, стараясь сдержать раздражение, - в этом как раз все .

 Мидж, я ни под каким видом не пущу тебя в кабинет директора. - Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата.  - Мне нужен список очередности работы на ТРАНСТЕКСТЕ. Если Стратмор обошел фильтры вручную, данный факт будет отражен в распечатке. - Какое отношение это имеет к директорскому кабинету.

Deductive and Inductive Arguments

Он попытался что-то сказать, но Сьюзан была полна решимости. Ей хотелось поскорее оказаться в Третьем узле, и она достаточно хорошо изучила своего шефа, чтобы знать: Стратмор никуда не уйдет, пока она не разыщет ключ, спрятанный где-то в компьютере Хейла. Ей почти удалось проскользнуть внутрь, и теперь она изо всех сил пыталась удержать стремившиеся захлопнуться створки, но на мгновение выпустила их из рук.
