Download or read book Pattern Recognition in Chemistry written by Kurt Varmuza and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical chemistry of the recent years is strongly influenced by automation. Data acquisition from analytica~ instruments - and some times also controlling of instruments - by a computer are principally solved since many years. Availability of microcomputers made these tasks also feasible from the economic point of view. Besides these basic applications of computers in chemical measurements scientists developed computer programs for solving more sophisticated problems for which some kind of "intelligence" is usually supposed to be necessary. Harm less numerical experiments on this topic led to passionate discussions about the theme "which jobs cannot be done by a computer but only by human brain ?~. If this question is useful at all it should not be ans wered a priori. Application of computers in chemistry is a matter of utility, sometimes it is a social problem, but it is never a question of piety for the human brain. Automated instruments and the necessity to work on complex pro blems enhanced the development of automatic methods for the reduction and interpretation of large data sets. Numerous methods from mathematics, statistics, information theory, and computer science have been exten sively investigated for the elucidation of chemical information; a new discipline "chemometrics" has been established. Three different approaches have been used for computer-assisted interpretations of chemical data. 1. Heuristic methods try to formu late computer programs working in a similar way as a chemist would solve the problem. 2.
Download or read book Dimensionality Reduction and Feature Selection Using a Mixed norm Penalty Function written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dimensionality reduction, which is the process of mapping high-dimension patterns to lower dimension subspaces, is a key issues in enhancing the processing efficiency of high dimensional data such as hyperspectral images. Dimensionality reduction has been widely discussed in the areas of data mining, image processing, pattern recognition, etc. Because in most situations, many of the dimensions are redundant or unnecessary for the tasks of interest, removing those dimensionality will produce more efficient computation while maintaining the original performance. Dimensionality reduction also reduces the measurement and storage requirements, reduces training and utilization times and it defies the curse of dimensionality to improve classification performance. Feature selection, the process of constructing and selecting the subsets of features that are useful to build a good predictor is of interest for many years. Before Kohavi and John published a special issue on feature selection in 1997, usually no more than 40 features are studied. Ever since then, people started looking at problems with hundreds to tens of thousands of features. Like dimensionality reduction, feature selection reduces the measurement and storage requirements, reduces training and utilization times, and it facilitates data visualization and data understanding. In this work, popular methods for dimensionality reduction and feature selection, such as vector space method, penalty function and support vector machine (SVM) are reviewed and compared. A novel penalty function called the mixed-norm penalty function is proposed. It minimizes the 1-norm of the weight vector while keeping the 2-norm constant. Both dimensionality reduction and feature selection in this work are realized via artificial neural networks (ANNs). Together with Bi-level optimization (BLO) technique, the mixed-norm penalty establishes great performance for both the synthetic data and hyperspectral images.

Book excerpt: This book presents recent developments and research trends in the field of feature selection for data and pattern recognition, highlighting a number of latest advances. The field of feature selection is evolving constantly, providing numerous new algorithms, new solutions, and new applications. Some of the advances presented focus on theoretical approaches, introducing novel propositions highlighting and discussing properties of objects, and analysing the intricacies of processes and bounds on computational complexity, while others are dedicated to the specific requirements of application domains or the particularities of tasks waiting to be solved or improved. Divided into four parts – nature and representation of data; ranking and exploration of features; image, shape, motion, and audio detection and recognition; decision support systems, it is of great interest to a large section of researchers including students, professors and practitioners.

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.
