This book was released on 2020 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision tree modelling, as one of data mining techniques, is used for credit scoring of bank customers. The main problem is the construction of decision trees that could classify customers optimally. This study presents a new hybrid mining approach in the design of an effective and appropriate credit scoring model. It is based on genetic algorithm for credit scoring of bank customers in order to offer credit facilities to each class of customers. Genetic algorithm can help banks in credit scoring of customers by selecting appropriate features and building optimum decision trees. The new proposed hybrid classification model is established based on a combination of clustering, feature selection, decision trees, and genetic algorithm techniques. We used clustering and feature selection techniques to pre-process the input samples to construct the decision trees in the credit scoring model. The proposed hybrid model choices and combines the best decision trees based on the optimality criteria. It constructs the final decision tree for credit scoring of customers. Using one credit data set, results confirm that the classification accuracy of the proposed hybrid classification model is more than almost the entire classification models that have been compared in this paper. Furthermore, the number of leaves and the size of the constructed decision tree (i.e. complexity) are less, compared with other decision tree models. In this work, one financial data set was chosen for experiments, including Bank Mellat credit data set.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present computational work focuses on the credit scoring. An improvement in the credit scoring models has been shown with the use of different feature selection methods and machine learning classifiers. In this paper, a comparative analysis has been performed between different machine learning classifiers such as Bayesian, Naïve Bayes, SVM (support Vector Machine), Decision Tree, Random Forest and the Feature selection techniques used for the analysis are Chi-Square, Information-gain and Gain-Ratio. Different metrics have been considered for analyzing the performance of models (such as False Positive rate, F-Measure, and Training time). After the analysis the best classifier and the feature selection algorithms have been found. In this study, the combination of Random Forest and Information Gain is found to be best among all other in respect to good performance accuracy and low false positive rate. However, training time of this combination was more. The result of SVM was comparable with the Random forest.

Download or read book Feature Extraction Construction and Selection written by Huan Liu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is broad interest in feature extraction, construction, and selection among practitioners from statistics, pattern recognition, and data mining to machine learning. Data preprocessing is an essential step in the knowledge discovery process for real-world applications. This book compiles contributions from many leading and active researchers in this growing field and paints a picture of the state-of-art techniques that can boost the capabilities of many existing data mining tools. The objective of this collection is to increase the awareness of the data mining community about the research of feature extraction, construction and selection, which are currently conducted mainly in isolation. This book is part of our endeavor to produce a contemporary overview of modern solutions, to create synergy among these seemingly different branches, and to pave the way for developing meta-systems and novel approaches. Even with today's advanced computer technologies, discovering knowledge from data can still be fiendishly hard due to the characteristics of the computer generated data. Feature extraction, construction and selection are a set of techniques that transform and simplify data so as to make data mining tasks easier. Feature construction and selection can be viewed as two sides of the representation problem.

Download or read book Feature Selection Techniques for Classification and Clustering written by Ananya Gupta and published by . This book was released on 2023-01-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several feature selection techniques that can be used for classification and clustering, including: Wrapper methods: These methods use a specific learning algorithm to evaluate the importance of each feature. Examples include forward selection and backward elimination. Filter methods: These methods use a statistical test to evaluate the importance of each feature. Examples include chi-squared test and mutual information. Embedded methods: These methods use a learning algorithm that has built-in feature selection capabilities. Examples include Lasso and Ridge regression in linear models. Hybrid methods: These methods combine the strengths of wrapper and filter methods. Correlation-based feature selection (CFS): This method uses correlation between features and the target variable to select the relevant features. Recursive Feature Elimination (RFE): This method recursively removing attributes and building a model on those attributes that remain. It uses the model accuracy to identify which attributes (and combination of attributes) contribute the most to predicting the target attribute. Overall, the choice of feature selection technique will depend on the specific problem and dataset at hand. The data mining tasks are often confronted with many challenges, biggest being the large dimension of the datasets. For successful data mining, the most important criterion is the dimensionality reduction of the dataset. The problem of dimensionality has imposed a very big challenge towards the efficiency of the data mining algorithms. The data mining algorithms cannot handle these high dimensional data as they render the mining tasks intractable. Thus, it becomes necessary to reduce the dimensionality of the data. There are two methods of dimensionality reduction. They are the feature selection and feature extraction methods (Bishop, 1995, Devijver and Kittler, 1982, Fukunaga, 1990). Feature selection method reduce the dimensionality of the original feature space by selecting a subset of features without any transformation. It preserves the physical interpretability of the selected features as in the original space. Feature extraction method reduce the dimensionality by linear transformation of the input features into a completely different space. The linear transformation involved in feature extraction cause the features to be altered, making their interpretation difficult. Features in the transformed space lose their physical interpretability and their original contribution becomes difficult to ascertain (Bishop, 1995). The choice of the dimensionality reduction method is completely application specific and depends on the nature of the data. Feature selection is advantageous especially as features keep their original physical meaning because no transformation of data is made. This may be important for a better problem understanding in some applications such as text mining and genetic analysis where only relevant information is analysed.
Download or read book Recent Methods from Statistics and Machine Learning for Credit Scoring written by Anne Kraus and published by Cuvillier Verlag. This book was released on 2014-07-08 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Credit scoring models are the basis for financial institutions like retail and consumer credit banks. The purpose of the models is to evaluate the likelihood of credit applicants defaulting in order to decide whether to grant them credit. The area under the receiver operating characteristic (ROC) curve (AUC) is one of the most commonly used measures to evaluate predictive performance in credit scoring. The aim of this thesis is to benchmark different methods for building scoring models in order to maximize the AUC. While this measure is used to evaluate the predictive accuracy of the presented algorithms, the AUC is especially introduced as direct optimization criterion.

Download or read book Consumer Credit Scoring Models with Limited Data written by Maja Sustersic and published by . This book was released on 2007 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we design the neural network consumer credit scoring models for financial institutions where data usually used in previous research are not available. We use extensive primarily accounting data set on transactions and account balances of clients available in each financial institution. As many of these numerous variables are correlated and have very questionable information content, we considered the issue of variable selection and the selection of training and testing sub-sets crucial in developing efficient scoring models. We used a genetic algorithm for variable selection. In dividing performing and nonperforming loans into training and testing sub-sets we replicated the distribution on Kohonen artificial neural network, however, when evaluating the efficiency of models, we used k-fold cross-validation. We developed consumer credit scoring models with error back propagation artificial neural networks and checked their efficiency against models developed with logistic regression. Considering the dataset of questionable information content, the results were surprisingly good and one of the error back propagation artificial neural network models has shown the best results. We showed that our variable selection method is well suited for the addressed problem.
