    Advances in Data Mining Knowledge Discovery and Applications aims to help data miners, researchers, scholars, and PhD students who wish to apply data mining techniques. The primary contribution of this book is highlighting frontier fields and implementations of the knowledge discovery and data mining. It seems to be same things are repeated again. But in general, same approach and techniques may help us in different fields and expertise areas. This book presents knowledge discovery and data mining applications in two different sections. As known that, data mining covers areas of statistics, machine learning, data management and databases, pattern recognition, artificial intelligence, and other areas. In this book, most of the areas are covered with different data mining applications. The eighteen chapters have been classified in two parts: Knowledge Discovery and Data Mining Applications

    Data mining in soft computing framework: a survey

    Get PDF
    The present article provides a survey of the available literature on data mining using soft computing. A categorization has been provided based on the different soft computing tools and their hybridizations used, the data mining function implemented, and the preference criterion selected by the model. The utility of the different soft computing methodologies is highlighted. Generally fuzzy sets are suitable for handling the issues related to understandability of patterns, incomplete/noisy data, mixed media information and human interaction, and can provide approximate solutions faster. Neural networks are nonparametric, robust, and exhibit good learning and generalization capabilities in data-rich environments. Genetic algorithms provide efficient search algorithms to select a model, from mixed media data, based on some preference criterion/objective function. Rough sets are suitable for handling different types of uncertainty in data. Some challenges to data mining and the application of soft computing methodologies are indicated. An extensive bibliography is also included

    Traditsioonilised sĂ”rmejĂ€lgede tuvastamise sĂŒsteemid kasutavad otsuste tegemisel minutiae punktide informatsiooni. Nagu selgub paljude varasemate tööde pĂ”hjal, ei ole sĂ”rmejĂ€lgede pildid mitte alati piisava kvaliteediga, et neid saaks kasutada automaatsetes sĂ”rmejĂ€ljetuvastuse sĂŒsteemides. Selle takistuse ĂŒletamiseks keskendub magistritöö vĂ€ga madala kvaliteediga sĂ”rmejĂ€lgede piltide tuvastusele – sellistel piltidel on mitmed ĂŒldteada moonutused, nagu kuivus, mĂ€rgus, fĂŒĂŒsiline vigastatus, punktide olemasolu ja hĂ€gusus. Töö eesmĂ€rk on vĂ€lja töötada efektiivne ja kĂ”rge tĂ€psusega sĂŒgaval nĂ€rvivĂ”rgul pĂ”hinev algoritm, mis tunneb sĂ”rmejĂ€lje Ă€ra selliselt madala kvaliteediga pildilt. Eksperimentaalsed katsed sĂŒgavĂ”ppepĂ”hise meetodiga nĂ€itavad kĂ”rget tulemuslikkust ja robustsust, olles rakendatud praktikast kogutud madala kvaliteediga sĂ”rmejĂ€lgede andmebaasil. VGG16 baseeruv sĂŒgavĂ”ppe nĂ€rvivĂ”rk saavutas kĂ”rgeima tulemuslikkuse kuivade (93%) ja madalaima tulemuslikkuse hĂ€guste (84%) piltide klassifitseerimisel.Fingerprint recognition systems mainly use minutiae points information. As shown in many previous research works, fingerprint images do not always have good quality to be used by automatic fingerprint recognition systems. To tackle this challenge, in this thesis, we are focusing on very low-quality fingerprint images, which contain several well-known distortions such as dryness, wetness, physical damage, presence of dots, and blurriness. We develop an efficient, with high accuracy, deep neural network algorithm, which recognizes such low-quality fingerprints. The experimental results have been conducted on real low-quality fingerprint database, and the achieved results show the high performance and robustness of the introduced deep network technique. The VGG16 based deep network achieves the highest performance of 93% for dry and the lowest of 84% for blurred fingerprint classes

    An overview of emerging pattern mining in supervised descriptive rule discovery: taxonomy, empirical study, trends, and prospects

    Get PDF
    Emerging pattern mining is a data mining task that aims to discover discriminative patterns, which can describe emerging behavior with respect to a property of interest. In recent years, the description of datasets has become an interesting field due to the easy acquisition of knowledge by the experts. In this review, we will focus on the descriptive point of view of the task. We collect the existing approaches that have been proposed in the literature and group them together in a taxonomy in order to obtain a general vision of the task. A complete empirical study demonstrates the suitability of the approaches presented. This review also presents future trends and emerging prospects within pattern mining and the benefits of knowledge extracted from emerging patternsSpanish Ministry of Economy and Competitiveness under the project TIN2015-68454-R (FEDER Founds

    Hybrid feature selection based ScC and forward selection methods

    Operational data is always huge. A preprocessing step is needed to prepare such data for the analytical process so the process will be fast. One way is by choosing the most effective features and removing the others. Feature selection algorithms (FSAs) can do that with a variety of accuracy depending on both the nature of the data and the algorithm itself. This inspires researchers to keep on developing new FSAs to give higher accuracies than the existing ones. Moreover, FSAs are essential for reducing the cost and effort of developing information system applications. Merging multiple methodologies may improve the dimensionality reduction rate retaining sensible accuracy. This research proposed a hybrid feature selection algorithm based on ScC and forward selection methods (ScCFS). ScC is based on stability and correlation while forward selection is based on Random Forest (RF) and Information Gain (IG). A lowered subset generated by ScC is fed to the forward selection method which uses the IG as a decision criterion for selecting the attribute to split the node of the RF to generate the optimal reduct. ScCFS was compared to other known FSAs in terms of accuracy, AUC, and F-score using several classification algorithms and several datasets. Results showed that the ScCFS excels other FSAs employed for all classifiers in terms of accuracy except FLM where it comes in second place. This proves that ScCFS is the pioneer in generating the reduced dataset with remaining high accuracies for the classifiers used
