Let us consider the following statement: "whatever numbers a and b may be, (a+b)2 = a2+2ab+ b2''. The above statement is a proposition; but the bare formula "(a + b)2 = a2 + 2ab + b2'' alone is not, since it asserts nothing definite unless it was further told, or led to suppose, that a and b are to have all possible values, or are to have such-and-such values. The former of these is tacitly assume

Logic is the science and art that so directs the mind in the process of reasoning and subsidiary process as to enable it to attain clearness, consistency and validity in those processes. The aim of logic is to secure clearness in the definition and arrangement of our ideas and other mental images, consistency in our judgement and validity in our process of inference. So, logic is "A formal way of

Usually mathematical theorems are stated in the form of an implication p --> q or equivalence. Here P is called the Premises or hypothesis and q is called conclusion.

In this unit we describe the process of derivation by which one demonstrates that a particular formula in a valid consequence of given set of premises. The method of derivation involving predicated statement calculus and also certain additional rules which are required to deal with the formulae involving quantifiers. The rules P and T, regarding the introduction of a premise at any stage of deriva

Title: MSCS-501 Discrete Mathematics

Mathematical logic or logic is the discipline that deals with the methods of reasoning. It provides rules and techniques for determining whether a given argument or mathematical proof or conclusion in a scientific theory is valid or not.
Title: Discrete Structures and Graph Theory

This chapter is a continuation of Chapter 2. Here, we present the topic of quantified statements and the methods of proof and disproof.

The scientific enterprise is built on a foundation of trust. Society trusts that scientific research results are an honest and accurate reflection of a researcher's work. Researchers equally trust that their colleagues have gathered data carefully, have used appropriate analytic and statistical techniques, have reported their results accurately, and have treated the work of other researchers with

In this chapter, we study the structure of simple and compound statement through various logical connectives and different type of combination of statements.
Title: Math 1.4 Discrete Mathematics

The dictionary meaning of the term "Logic" is the Science of reasoning correctly. The rules of logic is precise meaning to mathematics statements. These rules are used to distinguish between valid and invalid mathematics arguments. Logical reasoning is used in mathematics to prove theorems, in Computer Science to verify the correctness of program and to prove theorems, in natural and physical sci

16. Data Mining Functionalities and Data Cleaning(Computer Science)

Total View (735)

Data mining functionalities are used to specify the kind of patterns to be found in data mining tasks. In general, data mining tasks can be classified into two categories: descriptive and predictive. Descriptive mining tasks characterize the general properties of the data in the database. Predictive mining tasks perform inference on the current data in order to make
predictions.

• Simple and compound propositions - Logical connectives
• Tautology and contradiction - Logical equivalence
• Converse, inverse and contra positive of a given conditional

Title: Mathematics I

A popular misconception about data mining is to expect that data mining systems can autonomously dig out all of the valuable knowledge that is embedded in a given large database,without human intervention or guidance. Although it may at first sound appealing to have an autonomous data mining system, in practice, such systems will uncover an overwhelmingly large set of patterns.

Naturally we can now ask: Are there relations that simultaneously manifest all three properties? The answer is yes; For instance the relation is logically equivalent to on the set of propositions has all these properties. Such as a relation is an equivalence relation. For example in some programming languages .the names of variables can contain an unlimited

Combinatorics, the study of arrangements of objects is an important part of discrete mathematics. This subject was studied as long as the seventeenth century. When combination questions arose in the study of gambling games, Enumeration, the counting of objects with certain properties, is an important part of combinatorics. We must count object to solve many different type of problems for instance.

Methodology refers to the logical process of discerning the truth relating to its contents and establishing cause and effect relationship, thereby to evolve scientific generalisations. There are two logical methods namely Deductive and Inductive method. To establish the cause of economic events, economists generally use both these methods of reasoning.

In our day to day life, we use the word set in so many references. But, what are sets? Well, nobody could successfully define the term set. Who ever tried, could not stop from using synonyms as "class'', "collection'', and "aggregate''. Often sets are defined intuitively as an unordered collection of objects. But this definition does not specify "what an object is?'' Such definition leads to parad
