Although it has been shown in theory that prescriptive analytics improves decision-making more than predictive analytics, no empirical evi- dence has been presented in the literature on an elaborated application of both approaches that allows for a fair comparison of predictive and uplift modeling. -
Effective Extraction of Small Data from Large Database by Using Data Mining Technique
International Journal of Scientific & Engineering Research, Volume 7, Issue 4, April-2016 372 ISSN 2229-5518 Effective Extraction of Small Data from Large Database by using Data mining Technique. Mr. Parag Satish Kulkarni Miss.

Symbiosis International University. Abstract: The demand for extracting meaningful patterns in various applications is very necessary. Data mining is the process of automatically extracting meaningful patterns from usually very large quantities of seemingly unrelated data. When used in conjunction with the appropriate visualization tools, data mining allows the researcher to use highly advanced pattern-recognition skills and knowledge of molecular biology to determine which results warrant further study. Data mining is an automated means of reducing the complexity of data in large bioinformatics databases and of discovering meaningful, useful patterns and relationships in data. Data mining is one stage in an overall knowledge-discovery process. It is an iterative process in which preceding processes are modified to support new hypotheses suggested by the data. The process of data mining is concerned with extracting patterns from the data, typically using classification, regression, link analysis, and segmentation or deviation detection.

Machine Learning for Marketing Decision Support
Machine Learning for Marketing Decision Support Doctoral Thesis to acquire the academic degree of doctor rerum politicarum (Doctor of Economics and Management Science) submitted to School of Business and Economics Humboldt-Universität zu Berlin by M.Sc. Johannes Sebastian Haupt President of Humboldt-Universität zu Berlin: Prof. Dr.-Ing. Dr. Sabine Kunst Dean of the School of Business and Economics: Prof. Dr. Daniel Klapper Reviewers: 1. Prof. Dr. Stefan Lessmann 2. Prof. Dr. Daniel Guhl Date of Colloquium: 24 June 2020 2 Abstract The digitization of the economy has fundamentally changed the way in which companies interact with customers and made customer targeting a key intersection of marketing and information systems. Marketers can choose very specifically which customers to serve with a marketing mes- sage based on detailed demographic and behavioral information. Building models of customer behavior at the scale of modern customer data requires development of tools at the intersection of data management and statistical knowledge discovery. The application of these models for successful targeting requires deep understanding of the underlying marketing decision problem and awareness of the ethical implications of data collection. This dissertation widens the scope of research on predictive modeling by focusing on the in- tersections of model building with data collection and decision support. Its goals are 1) to develop and validate new machine learning methods explicitly designed to optimize customer targeting decisions in direct marketing and customer retention management and 2) to study the implications of data collection for customer targeting from the perspective of the company and its customers. The thesis addresses the first goal by proposing methods that utilize the richness of e-commerce data, reduce the cost of data collection through efficient experiment design and address the tar- geting decision setting during model building. -
Predictive Analytics Using R
Predictive Analytics using R Dr. Jeffrey Strickland is a Senior Predictive Analytics Consultant with over 20 years of Predictive Analytics expereince in multiple industiries including financial, insurance, defense and NASA. He is a subject matter expert on mathematical and statistical modeling, as well as machine using R learning. He has published numerous books on modeling and simulation. Dr. Strickland resides in Colorado. This book is about predictive analytics. Yet, each chapter could easily be handled by an entire volume of its own. So one might think of this a survey of predictive modeling, both statistical (parametric and nonparametric), as well as machine learning. We define predictive model as a statistical model or machine learning model used to predict future behavior based on past behavior. In order to use this book, one should have a basic understanding of mathematical statistics (statistical inference, models, tests, etc.) — this is an advanced book. Some theoretical foundations are laid out (perhaps subtlety) but not proven, but references are provided for additional coverage. Every chapter culminates in an example using R. R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. To download R, please choose your preferred CRAN mirror at http://www.r-project.org/. An introduction to R is also available at http://cran.r-project.org /doc/manuals/r-release/R-intro.html. The book is organized so that statistical models are presented first (hopefully in a logical order), followed by machine learning models, and then applications: uplift modeling and time series. -
Machine Learning Based Prediction and Classification for Uplift Modeling

Uplift modeling requires the existence of a treatment group as well as a control group and the objective hence becomes estimating the difference between the success probabilities in the two groups. Efficient methods for estimating the probabilities in uplift models are statistical machine learning methods. In this project the different uplift modeling approaches Subtraction of Two Models, Modeling Uplift Directly and the Class Variable Transformation are investigated. The statistical machine learning methods applied are Random Forests and Neural Networks along with the standard method Logistic Regression. The data is collected from a well established retail company and the purpose of the project is thus to investigate which uplift modeling approach and statistical machine learning method that yields in the best performance given the data used in this project. -
Decision Trees for Uplift Modeling with Single and Multiple Treatments
Knowl Inf Syst (2012) 32:303–327 DOI 10.1007/s10115-011-0434-0 REGULAR PAPER Decision trees for uplift modeling with single and multiple treatments Piotr Rzepakowski · Szymon Jaroszewicz Received: 27 January 2011 / Revised: 16 May 2011 / Accepted: 12 July 2011 / Published online: 29 July 2011 © The Author(s) 2011. This article is published with open access at Springerlink.com Abstract Most classification approaches aim at achieving high prediction accuracy on a given dataset. However, in most practical cases, some action such as mailing an offer or treating a patient is to be taken on the classified objects, and we should model not the class probabilities themselves, but instead, the change in class probabilities caused by the action. The action should then be performed on those objects for which it will be most profitable. This problem is known as uplift modeling, differential response analysis, or true lift modeling, but has received very little attention in machine learning literature. An important modification of the problem involves several possible actions, when for each object, the model must also decide which action should be used in order to maximize profit. In this paper, we present tree- based classifiers designed for uplift modeling in both single and multiple treatment cases. To this end, we design new splitting criteria and pruning methods. The experiments confirm the usefulness of the proposed approaches and show significant improvement over previous uplift modeling techniques. Keywords Uplift modeling · Decision trees · Randomized controlled trial · Information theory 1 Introduction and notation In most practical problems involving classification, the aim of building models is to later use them to select subsets of cases to which some action is to be applied.
