CHAPTER TWO LITERATURE REVIEW 2.0 INTRODUCTION Data is derived from the Latin word “Datum” and can be defined as a representation of facts, concepts or instructions in a formalized manner suitable for communication, interpretation, or processing by humans or by automatic means (Hicks 1993). Data is referred to as just mere facts unless processed to obtain information and knowledge. They can be classified into three levels of abstraction with data being the lowest level of abstraction and knowledge the highest level of abstraction. In the last decade, the amount of data collected and generated in all industries is growing at a fast rate (Brachman et al., 1996). From the financial sector, to the manufacturing industries to the medical sector …show more content…
The developments of various systems achieved with the concept of machine have been tre 2.1.1APPLICATION OF MACHINE LEARNING According to (Shhab, et al.) the following are some applications of machine learning. Diagnosis: Defining malfunctions based on an object behavior then recommending solutions. Pattern Recognition: Identification of objects and images by their shapes, forms, outlines, color, surface, texture, temperature, or other attribute, usually by automatic means. Prediction: Predicting the behavior of an object in the future pertaining to its past one. Classification: Assigning an object to a pre-defined class. Clustering: Dividing a heterogeneous group of objects into homogeneous subgroups. Optimization: Improving the quality of solutions until an optimal one is found. Control: Governing the behavior of an object to meet specified …show more content…
Rough set evolved from the fact that in classical set theory, data was grouped or classified as either a subset or a complement of the set. Rough set was created to handle those data sets that can neither stand as a subset nor a complement of the set. It is important to note that one of the significance of rough set that makes it unique and sort after is that it deals with uncertainty and decision making under circumstances with insufficient information and also it does not need any preliminary or additional information about the data. Therefore, it classifies imprecise, uncertain or incomplete information expressed in terms of data. Rough set deals with classificatory analysis of data tables, the data can be acquired from either from measurements or records (such as financial records, stock rates, medical records or reports, students’ attendance score or report, examination scores, scientific reports, etc.) or human experts and the sole aim of rough set is to analyze and combine approximations of concepts from the acquired data. The dataset usually represented in a tabular form is known as the Information
Although the American economy is improving from the great recession , the middle class is shrinking, a problem for a consumerist based economy where the middle class makes up the consumerists. Every industry has a place in today’s world, however some industries are losing importance while others
New York and Chicago were the main cities. They let the job opportunities
Businesses like oil, the telephone, and the Bessemer Process really helped. Oil replaced whale oil and the telephone helps us communicate long distances. The Bessemer Process sped up the
Many people in the company need access to data to help them do their job better. The main questions revolve around who needs what data, and who chooses what data gets to be shared. Looking at all the pieces, as well as the IT and information assets, the governance of the data belongs to a data owner (Khatri & Brown, 2010). The main questions to be answered must include who is the data owner? Who is responsible for data quality?
Answer: (a): Market segmentation is the first step in defining and selecting a target market to pursue and penetrate. Basically, market segmentation is the process of splitting up an overall market into two or more groups/classes of consumers. Each group of consumers is called as a market segment. Each group (or market segment) should be similar in terms of certain characteristics or product/ service needs. In business world, market segmentation is considered to be a most important tool in enabling marketers to better meet customer needs and requirements.
One of the most well-known economic industries in America is manufacturing. Manufacturing contributes $ 2.09 trillion directly to the economy. This industry is expanding and growing in the USA meaning there is an increase in the outcome of this industry. Many people work in this industry which means that they earn money, and no one is poor anymore in the USA. Because of many people working in manufacturing, the economy of the USA has increased dramatically.
The Food Industry The food industry is the worldwide diversified industry which has to do with anything relevant with food from food education to marketing but principally the industry produces and or provides food to essentially all people on the planet. The only people who are excluded from the food industry are self-sustaining farmers and hunter-gatherers. It is one of the largest industries in the world and continues to grow because people need food and the population is increasing every day. In America, the food industry possesses such an important role, yet there are so many problems within the industry which is ruining the society as we know it.

Data item is a set of description which gives information but does not convey a meaning. ii) Information: As stated above the sales resulted in over $1 billion but actually the 10 percent of those sales were from the Internet store.
Computers permit large amounts of data to be stored, either on the computer's hard disk or in portable diskettes. Data Manipulation and Processing Data manipulation and processing are performed to obtain useful information from data previously entered into the system. Data manipulation embraces two types of operations: operations needed to remove errors and update current data sets and operations using analytical techniques to answer specific questions formulated by the user. The manipulation process can range from the simple overlay of two or more maps to a complex extraction of disparate pieces of information from a wide variety of sources. Data Output Data output refers to the display or presentation of data employing commonly used output formats that include maps, graphs, reports, tables, and charts, either as a hard-copy, as an image on the screen, or as a text file that can be carried into other software programs for further analysis.
1.1 INTRODUCTION In modern day, vehicles anti-theft system is our prime important duty to secure our vehicle by the means of fingerprinting. The main focus while developing the vehicle anti-theft system is to protect our system from theft by providing the anti-theft protection. For the protection, first we should restrict the unlocking of vehicle, only to the authorized persons have this ability to unlock the car without the use of keys, once it has identified by the Fingerprint sensor. The Fingerprint of the owner and other authorized persons are stored into the database beforehand and at the time of starting engine of the vehicle, scanned fingerprints are being crosschecked with the database.
Technology is growing at a fast pace and every day we see a new product or service that is available. Many times it is hard to even keep up with the latest phone, computer, game console, or software. There are so many different gadgets to choose from and even the internet is on information overload. As a result, we can no longer truly expect to have privacy.

I do not believe the field has been developed to its potential in any regard, and feel that considerable progress can be made to improve the interactive experience that users have with an artificial intelligence application. This genuine intrigue combined with my curiosity for the subject matter and the limitless potential of the field are the reason why I wish to pursue a greater depth of knowledge in artificial
1) INTRODUCTION Education is an important thing for all people, especially to students who will grow up and will develop advanced countries. Education is not only to go to school but also education can be obtained everywhere now, for or example, at home. Parents can teach their children. By using the sophisticated technology now, education can also be easily found. Technology is a type of electrical system or digitally generated to facilitate everyone in manual.
