The process of applying machine learning to data mining may require many trials, backtracking, and multiple executions of different learning and inference procedures. Such a process can be time-consuming, laborious, and prone to errors. To overcome these problems, this paper proposes an integration of diverse learning and inference procedures into a system that can automatically pursue differen...

Software systems are growing in size and complexity. Increased complexity often leads to decresed mainainability and bad modularity, and re-engineering tasks is often performed in order to increase the key qualities of the system. With the incentive of a growing attention to aspect-oriented programming, the efforts to devise new techniques for refactoring legacy system into an aspect-oriented d...

Sophisticated Data Mining tools are able to provide valuable information for online retailers. But especially when an external data mining service provider is contracted, important questions arise concerning the privacy preservation of the shop customers. This paper discusses the specific case of an online retailer who aims at usefully analysing customers’ data for product and capacity planning...

Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price. Metal price fluctuations in recent years were exaggerated and impose...

conclusions: the current study presents the highest accuracy value to diagnose the lad stenosis in the literature. results: bagging and c4.5 classification algorithms were drawn upon to analyse the data, the former reaching accuracy rates of 79.54%, 61.46%, and 68.96% for the diagnosis of the stenoses of the left anterior descending (lad), left circumflex (lcx), and right coronary artery (rca),...

Resources/reserves classification is crucial for block model creation utilised in mine planning and feasibility study. Selection of estimation methods is an essential part of mineral exploration and mining activities. In other word, resources classification is an issue for mining companies, investors, financial institutions and authorities, but it remains subject to some confusion. The aim of t...

A three-dimensional Geo-Information System (GIS) for planning and operating a mine is described. On a conceptual level, the underlying database is speciied using the notation of Rumbaugh's Object Modeling Technique (OMT). The paper focuses on the problems caused by the implementation of such an Object Oriented Data Model by at relations as provided by a standard RDBMS. A running implementation ...
