Data Mining of Inputs: Analysing Magnitude and Functional Measures

Tamás D. Gedeon
1997 International Journal of Neural Systems  
This paper examines the use of weight matrix analysis techniques and functional measures using two real (and hence noisy) data sets.  ...  The second part of this paper examines the use of measures to determine the functional contribution of inputs to outputs.  ...  The experimental work demonstrated that the functional measures, particularly based on the analysis of the network and not just the data, produce better indicators of the significance of particular inputs  ...

Utility based data mining for time series analysis

Sven F. Crone, Stefan Lessmann, Robert Stahlbock
2005 Proceedings of the 1st international workshop on Utility-based data mining - UBDM '05  
Conversely, data mining methods for regression and time series analysis generally disregard economic utility and apply simple accuracy measures.  ...  In corporate data mining applications, cost-sensitive learning is firmly established for predictive classification algorithms.  ...  Similarly, for the predictive data mining problems of regression and time series analysis [10, 11] the costs arising from invalid point prediction of the true realisation increase with the magnitude  ...

The application of data mining techniques for the regionalisation of hydrological variables

M. J. Hall, A. W. Minns, A. K. M. Ashrafuzzaman
2002 Hydrology and Earth System Sciences  
However, hydrological regionalisation can also be regarded as a problem in data mining -a search for useful knowledge and models embedded within large data sets.  ...  This approach has been applied to three data sets from the south-west of England and Wales; to England, Wales and Scotland (EWS); and to the islands of Java and Sumatra in Indonesia.  ...  In contrast, when the data sets were analysed using a data mining technique involving unsupervised learning, three classes of catchment were identified for both Indonesia and south-west England and Wales  ...

Using Data Mining for Static Code Analysis of C [chapter]

Hannes Tribus, Irene Morrigl, Stefan Axelsson
2012 Lecture Notes in Computer Science  
Due to the general interest in code quality and the availability of large open source code bases as test and development data, we believe this problem should be of interest to the larger data mining community  ...  In this work we extend our previous approach and investigate a new way of doing feature selection and test the suitability of many different learning algorithms.  ...  Static Analysis by Data Mining We now arrive at the problems of how to transform static source code to a suitable format for data mining, which data to use to train the classifier, and which classifier  ...
