To reduce microprobe usage we use data smoothing techniques to reveal changing patterns with modest X-ray count accumulations at individual data points. In this paper we review performance for revealing pattern
smoothing noisy data, removing inconsistencies, and analyzing and removing outliers that lead to correcting data and removing all kinds of errors from the dataset. It’s a very critical step in the data mining process as it ensures accuracy and consistency and even...
This book is aboutmachine learning techniquesfordata mining: the technical core of practicaldata mining applications.Successful implementationof these techniques in abusiness contextrequires an understanding of important aspects that we do not—and cannot—cover in this book. Fig. 1.4shows the life cycl...
Data Mining is a process to identify interesting patterns and knowledge from a large amount of data. In these steps, intelligent patterns are applied to extract the data patterns. The data is represented in the form of patterns and models are structured using classification and clustering technique...
Data in the real world is quite dirty and corrupted with inconsistencies, noise, incomplete information, and missing values. It is aggregated from diversified sources using data mining and warehousing techniques. It is a common thumb rule inmachine learningthat the greater the amount of data we ha...
In this paper, some preliminary work regarding two different data mining algorithms (self organizing maps and smoothing filters) is presented. These techniques can be used in combination with databases of observations to provide downscaled local forecasts from operative model outputs. This is a more ...
Frequency of published papers in six medical tasks can be shown inFig. 22. In each task, frequency ofdata miningapproach is given.Classification algorithmsappear as the most used in all tasks. Regression based algorithms are known as basic statistical techniques used to do valuable traditional stud...

Data mining is the use of various techniques to discover knowledge from massive data, it has wide application and prospect. The article detailed introduction summarizes the concept of data mining, methods, and applications. And analysis, summarizes the application of data mining in the financial fiel...
2.1.2.3 Exponential smoothing models Exponential smoothing techniques are generally considered a collection of ad hoc techniques useful for extrapolating univariate time series of various kinds. In spite of its huge popularity in business and industrial domains, it has received comparatively less attention...
