Show all documents Indebted households profiling: a knowledge discovery from database approach In order to build such risk profiles it is necessary to employ an approach that analyses data systematically in order to detect important relationships, interactions, dependencies and associations amongst the available continuous and categorical variables altogether and accurately generate profiles of most interesting household segments according to their credit risk.
This way, the objective of this work is to employ a knowledge discovery from database KDD process to identify groups of households and describe their profiles using a database collected by the Consumer Credit Counselling Service CCCS in the UK. Thus, it was proposed a framework to meet two requirements: First, it must allow the usage of both categorical and continuous data altogether; second, it must be unsupervised, since we are trying to find hidden structures in unlabelled data. Furthermore, clients of counselling organizations have an incentive to reveal true information to debt counsellors in order to gain better financial advice.

A goal for PPKD is to build a foundation for the application of knowledge discovery based on CAPP database from an interdisciplinary perspective including artificial intelligence, database , software technology, statistics, and management.
Data Mining and Knowledge Discovery in Database Abstract — Knowledge discovery and data mining have become areas of growing significance because of the recent increasing demand for KDD techniques, including those used in machine learning, databases, statistics, knowledge acquisition, data visualization, and high performance computing. The motive of mining is to find a new generation of computational theories and tools to assist humans in extracting useful information knowledge from the rapidly growing volumes of digital data.
This article provides real-world applications, specific data- mining techniques, challenges involved knowledge discovery. These techniques and tools are the subject of the emerging field of knowledge discovery in databases KDD. KDD has evolved from interaction and cooperation among such different fields as machine learning, pattern recognition, database , statistics, artificial Intelligence, knowledge representation, and knowledge acquisition for intelligent systems.
The goal of this database is to make the data collected available to planners, government officials, and the public, to be used to make strategic decisions for planning relevant interventions. Design and development of intelligent knowledge discovery system for stock exchange database Association rule is a popular data mining task for discovering knowledge from large amount of data in databases. It has been applied successfully in a wide range of business predicting problems Bing and Wynne, ; Ke et al.
Pasquier and Bastide proposed a new efficient algorithm, called a-close, for finding frequent closed itemsets and their support in a stock market database. A- close algorithm used closed itemset lattice framework that can be used for discovering frequent itemsets from stock market. Some advantages of a-close method and algorithms for the generation of all frequent itemsets and reduced itemsets from a database can be found in appendix B. However, a-close method is costly when mining long patterns or with low minimum support threshold in large database like stock market, and also it cannot generate association rules at higher levels.
Typical algorithms for discovering frequent itemsets in stock market by using association rules operate in a bottom-up, breadth-first search direction Lin and Kedem, The computation starts from frequent 1-itemsets the minimum length frequent itemsets and continuous until all maximal length frequent itemsets are found. During the execution, every frequent itemset is explicitly considered. Such algorithms perform well when all maximal frequent itemsets are short. However, performance drastically depreciates when some of the maximal frequent itemsets are long.
Generally use extraction of association rules for data mining. Now researchers focus on extracting informative knowledge in complex data. A pattern is considered as informative if user can act upon it for his advantage. Real time complex data consists of vast information. For mining effective patterns, existing single traditional data mining method is not enough. To acquire knowledgeable information from data source we should integrate one or more data mining methods.
Combined mining approach implemented with different data mining algorithms on medical field data set. It is the process that results in the discovery of new patterns in large data sets.
It is a useful method at the intersection of artificial intelligence, machine learning, statistics, and database systems. It is the principle of picking out relevant information from data. It is usually used by business intelligence organizations, and financial analysts, to extract useful information from large data sets or databases DM is use to derive patterns and trends that exist in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.
Using rough set through for classification of image segmentation data Data mining also known as Knowledge Discovery in Database KDD can be defined as a technology or a process that helps to extract valuable information including hidden and unseen patterns, trends and relationships between variables from a large amount of data.
The information learnt and the discovery made can help in applying the new found patterns to unseen data that can guide and facilitate a crucial business decision making task. Data mining comprises several tasks such as classification, forecasting, prediction, clustering, association, deviation detection and so on. The definitive objective of data mining, in general, is to facilitate the prediction activity. Predictive knowledge discovery in database KDD is the most shared and common type that has the most direct impact in business applications .
The data mining process basically comprises of three stages: a an initial exploration, b a model design for pattern definition and c an implementation of the proposed model in the new or unseen data for the prediction purpose. To Study the Principles of Knowledge Discovery in Database The traditional method of turning data into knowledge relies on manual analysis and interpretation.
For example, in the health-care industry, it is common for specialists to periodically analyze current trends and changes in health-care data, say, on a quarterly basis. The specialists then provide a report detailing the analysis to the sponsoring health-care organization; this report becomes the basis for future decision making and planning for health- care management.
In a totally different type of application, planetary geologists sift through remotely sensed images of planets and asteroids, carefully locating and cataloging such geologic objects of interest as impact craters.
For these and many other applications, this form of manual probing of a data set is slow, expensive, and highly subjective. In fact, as data volumes grow dramatically, this type of manual data analysis is becoming completely impractical in many. Survey on Knowledge Discovery in Database and Challenges in KDD In the past two decadeshas seen a dramatic increase in the amount of information or data being stored in electronic format. This accumulation of data has taken place at an explosive rate.
It has been estimated that the amount of information in the world doubles every 20 months and the size and number of databases are increasing even faster. The increase in use of electronic data gathering devices such as point-of-sale or remote sensing devices has contributed to this explosion of available data Knowledge Discovery and Data mining KDD emerged as a rapidly growing interdisciplinary field that merges together databases, statistics, machine learning and related areas in order to extract valuable information and knowledge in large volumes of data With the rapid computerization in the past two decades, almost all organizations have collected huge amounts of data in their databases.
Data mining is a step in the knowledge discovery process consisting of particular data mining algorithms that, under some acceptable computational efficiency limitations, finds patterns or model in data.
Clustering and Hiding Sensitive Data for Social Network Dataset Data Mining is used for analyzing data from various perspectives that converts the previously unknown information into potentially useful data from huge databases.
The data Mining process is used to provide novel and hidden patterns in the data. Data Mining refers to using a variety of techniques to identify suggest of information or decision making knowledge in the database. They are used in areas such as decision support, predictions, forecasting. Data mining technique includes, Association rules, Clustering, Classification and Prediction. All images from the database have JPEG format and are of different dimensions.
The database used in the learning process is categorized into 50 semantic concepts. The system learns each concept by submitting approximatively 20 images per category.
Even if the annotation system is based on learning, this can be used for images from different domains. Some examples of the images category from the learning database are illustrated in Figure 5. Intelligent Quality Management Expert System Using PA-AKD in large Databases Data preparation module can reduce data dimensions furthermore, enhance valuable quality information and simplify the operation effectively, through eliminating unnecessary or lighter influential attribute.
Analyzing data is an important and exciting step in the quality control process. It is the time that you may reveal important facts about your customers, uncover trends that you might not otherwise have known existed, or provide irrefutable facts to support your plans. By doing in-depth data comparisons, you can begin to identify relationships between various data that will help you understand more about your respondents, and guide you towards better decisions.
In the module, there are three main links namely, data selection, preprocessing, data reduction. Data selection is used to collect relevant data from the primary quality database according to the need for quality knowledge discovery. The main function of preprocessing is reducing the noise, looking over integrality and consistency of quality data and dispelling the redundant data.
Data reduction can analyze the initial characteristic attribute of the dataset further after reducing the amount of test data. This paper discusses the idea of data mining, the process of KDD, different techniques such as clustering, association, classification, prediction and so on. We also discussed some insights of the data mining applications.
Data mining applications can use a variety of parameters to examine the data as an application, compared to other data analysis applications, such as structured queries or statistical analysis Software, data mining represents a difference of kind rather than degree.
Data mining involves the use of data analysis tools to discover previously unknown, valid patterns and relationships in large data sets Data mining is becoming increasingly common in both the private and public sectors.
Data mining applications in various fields use the variety of data types. The different methods of data mining are used to extract the patterns and thus the knowledge from this variety databases. Efficient and effective data mining in large database poses numerous requirements and great challenges to researchers and developers. The dramatically increasing demand for better decision support is answered by an extending availability of knowledge discovery , and data mining is one step at the core of the knowledge discovery process.
Data Mining is not a new term, but in the recent years its growth day by day touches great horizons. It has spread in almost all areas nowadays. It is clear that Data Mining tools helps in extracting useful or meaningful knowledgeable attributes or information from the unimaginable massive data.
This review would be helpful for the researchers to focus on the various issues of data mining. In future, we will review the popular classification algorithms and significance of their evolutionary computing approach in designing of efficient classification algorithms for data mining.
To derive families of faults, clustering methods are used. Telecommunications: The telecommunications alarm-sequence analyzer TASA was built in cooperation with a manufacturer of telecommunications equipment and three telephone networks Mannila, Toivonen, and Verkamo The system uses a novel framework for locating frequently occurring alarm episodes from the alarm stream and presenting them as rules.
Large sets of discovered rules can be explored with flexible information-retrieval tools supporting interactivity and iteration. In this way, TASA offers pruning, grouping, and ordering tools to refine the results of a basic brute-force search for rules. It was used successfully on data from the Welfare Department of the State of Washington. News Finally, a novel and increasingly important type of discovery is one based on the use of intelligent agents to navigate through an information-rich environment.
Although the idea of active triggers has long been analysed in the database field, really successful applications of this idea appeared only with the advent of the Internet. These systems ask the user to specify a profile of interest and search for related information among a wide variety of public-domain and proprietary sources. These are just a few of the numerous such systems that use KDD techniques to automatically produce useful information from large masses of raw data. See Piatetsky-Shapiro et al.
Knowledge Discovery Models for Product Design, Assembly Planning and Manufacturing System Synthesis Existing methods for retrieval or knowledge -based assembly sequence generation rely on retrieving the most similar existing product variant with respect to commonality of product components and assembly structure Dong et al.
The assembly sequence plan of such a retrieved product variant is then used as a preliminary one for the new variant.
The assembly sequence data i. Thus, the critical limitation of individual assembly sequence retrieval methods is that the assembly sequence data for a given new combination of components that has never existed together before in an existing variant could not be captured.

Никто никогда не позволял себе говорить с заместителем директора АНБ в таком тоне.
Knowledge Discovery in Databases: An Overview
Последний месяц был для Лиланда Фонтейна временем больших ожиданий: в агентстве происходило нечто такое, что могло изменить ход истории, и, как это ни странно директор Фонтейн узнал об этом лишь случайно. Три месяца назад до Фонтейна дошли слухи о том, что от Стратмора уходит жена. Он узнал также и о том, что его заместитель просиживает на службе до глубокой ночи и может не выдержать такого напряжения. Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил. Стратмор был блестящим специалистом, возможно, лучшим в агентстве.
Замечательно. Он опустил шторку иллюминатора и попытался вздремнуть. Но мысли о Сьюзан не выходили из головы. ГЛАВА 3 Вольво Сьюзан замер в тени высоченного четырехметрового забора с протянутой поверху колючей проволокой. Молодой охранник положил руку на крышу машины. - Пожалуйста, ваше удостоверение.
Сьюзан подумала о Стратморе, о том, как мужественно он переносит тяжесть этого испытания, делая все необходимое, сохраняя спокойствие во время крушения. Иногда она видела в нем что-то от Дэвида. У них было много общего: настойчивость, увлеченность своим делом, ум. Иногда ей казалось, что Стратмор без нее пропадет; ее любовь к криптографии помогала коммандеру отвлечься от завихрений политики, напоминая о молодости, отданной взламыванию шифров. Но и она тоже многим была обязана Стратмору: он стал ее защитником в мире рвущихся к власти мужчин, помогал ей делать карьеру, оберегал ее и, как сам часто шутил, делал ее сны явью. Хотя и ненамеренно, именно Стратмор привел Дэвида Беккера в АНБ в тот памятный день, позвонив ему по телефону. Мысли Сьюзан перенеслись в прошлое, и глаза ее непроизвольно упали на листок бумаги возле клавиатуры с напечатанным на нем шутливым стишком, полученным по факсу: МНЕ ЯВНО НЕ ХВАТАЕТ ЛОСКА, ЗАТО МОЯ ЛЮБОВЬ БЕЗ ВОСКА.

То, что там происходит, серьезно, очень серьезно. Мои данные еще никогда меня не подводили и не подведут. - Она собиралась уже положить трубку, но, вспомнив, добавила: - Да, Джабба… ты говоришь, никаких сюрпризов, так вот: Стратмор обошел систему Сквозь строй. ГЛАВА 100 Халохот бежал по лестнице Гиральды, перепрыгивая через две ступеньки. Свет внутрь проникал через маленькие амбразуры-окна, расположенные по спирали через каждые сто восемьдесят градусов. Он в ловушке.
