EN Airborne laser scanning (ALS) is one of the LIDAR technologies (Light Detection and Ranging). It provides information about the terrain in form of a point cloud. During measurement is acquired: spatial data (object’s coordinates X, Y, Z) and collateral data such as intensity of reflected signal. The[...]

EN Definition of a composite [1] describes an ideal composite material with perfect structure. In real composite materials, structure is usually imperfect - composites contain various types of defects [2, 3-5], especially as the casted composites are of concern. The reason for this is a specific struct[...]
Rudy i Metale Nieżelazne
2012 R. 57, nr 10 663-666
PL Aktualne rozwiązania klasyfikacji polskich rud metali nieżelaznych cechuje stosunkowo niska skuteczność jak i krótka żywotność urządzeń. W celu sprostania wymaganiom, koniecznym staje się wprowadzenie do eksploatacji nowoczesnych, w pełni zautomatyzowanych urządzeń klasyfikujących oraz zapewnienie s[...]
EN The current solutions of classification the Polish non-ferrous metal ores are characterized by a low efficiency of the process and the short life of machines. In order to meet the demands, it becomes necessary an introduction of modern, fully automated machines for classification and stabilization a[...]
Journal of Theoretical and Applied Computer Science
EN This paper describes an application of data mining, namely classification, with respect to 3-D surface analysis. More specifically in the context of sheet metal forming, especially Asymmetric Incremental Sheet Forming (AISF). The issue with sheet metal forming processes is that their application res[...]

EN In this paper we review Lattice Machine, a learning paradigm that “learns” by generalising data in a consistent, conservative and parsimonious way, and has the advantage of being able to provide additional reliability information for any classification. More specifically, we review the related conce[...]
PL W artykule zebrano informacje dotyczące klasyfikacji i oznakowania produktów do układania płytek, do wykonywania i napraw posadzek, do izolowania i renowacji budowli oraz zapraw i szpachlówek.
Fundamenta Informaticae
EN In this paper, we introduce a method for measuring similarity of objects of a relational database (relational objects, in short). We also propose and investigate an algorithm SC for classification of relational objects. The task of classification is carried out based on similarity of the objects to [...]
Systems Science
EN This study compares the performance of decision tree (CART) and two neural network configurations, namely a well-known Multilayer Perceptron Neural Network (MLP NN) and the Radial Basis Function Neural Network (RBF NN) on the radar ionosphere databases. The task is to discriminate between radar retu[...]
TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk
EN The concept of utilizing association rules for classification has emerged in recent years. This approach has often proved to be more efficient and accurate than traditional techniques. In this paper we extend the existing associative classifier building algorithms and apply them to the problem of im[...]
Gospodarka Wodna
2003 Nr 7 290-292
PL Artykuł zawiera krótki przegląd metod klasyfikacji jakości wód stosowanych obecnie w Polsce oraz zasady klasyfikacji podane w dyrektywach Unii Europejskiej. Autorzy przedstawiają również projekt nowej metody klasyfikacji opartej na parametrach chemicznych i uwzględniającej podział jakości wód na pię[...]
EN The paper contains a brief description of methods of classification of the quality of water being used at present in Poland and the principles of classification given by Directives of the European Union. The Authors present also a proposal for a new method of classification based on the chemical par[...]
TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk
1999 Vol. 3, No 4 483-488
EN A database containing statistically meaningful numbers of carefully verified cases of nevi pigmentosi (in four categories: benign nevus, blue nevus, suspicious nevus, and malignant melanoma) is described. Various experiments of controlled data mining were performed in order to gain insight into the [...]
Fundamenta Informaticae
EN In this paper we present an aggregation method which can be applied to classifications having different vocabularies. The method uses the rank distance (Dinu, 2003), a metric which measures the similarity between two hierarchies based on the ranks of objects. We define the aggregation of n hierarch[...]

EN In this paper supervised and unsupervised neural networks have been applied. To help the inexperienced transformer oil analyst to make good diagnosis, by classifying the transformer oil in classes giving its dielectric and cooling state; a Bayesian network a self organization map and a competitive l[...]
Surowce i Maszyny Budowlane
2004 nr 2 56-59
PL W artykule scharakteryzowano smary plastyczne, opisano cechy podstawowych smarów, podano ich klasyfikację.
Problemy Techniki Uzbrojenia
PL W artykule przedstawiono definicje, klasyfikację oraz przykłady zapalników w poszczególnych grupach klasyfikacyjnych. Omówione też zostały główne wymagania stawiane przed zapalnikami w poszczególnych grupach, a także sposoby ich realizacji wraz z rozwojem techniki wojennej. Jest on próbą zebrania po[...]
EN In the paper the definitions and the proposals of classification of fuses were presented. The main requirements for particular categories of fuses were also discussed.
Journal of Theoretical and Applied Computer Science
EN One source of EEG data quality deterioration is noise. The others are artifacts, such as the eye blinking, oculogyration, heart beat, or muscle activity. All these factors mentioned above contribute to the disappointing and poor quality of EEG signals. There are some solutions which allow increase o[...]
Physicochemical Problems of Mineral Processing
EN The use of centrifugal gravity concentration in the closed-grinding circuit of a gold-containing massive sulphide ore was tested on classifier underflow and overflow. A continuous Knelson CVD6 was retrofitted to the hydrocyclone underflow for recovery of Au and Pb at a coarser feed size. The objecti[...]

EN A novel approach to Gabor filtering of color textures in introduced. It is based on the complex chromatic Fourier transform.Complex colors are derived from the HSL color space representing intensity-independent color textures.Additionally, a novel Gabor texture feature for the grayscale as well as t[...]

EN This paper presents a new model of an artificial neural network solving classification problems, called Local Transfer Function Classifier (). Its architecture is very similar to this of the Radial Basis Function neural network (RBF), however it utilizes an entirely different learning algorithm. Thi[...]

2015 nr 12 53--61
EN In this paper, a novel approach for coding nominal data is proposed. For the given nominal data, a rank in a form of complex number is assigned. The proposed method does not lose any information about the attribute and brings other properties previously unknown. The approach based on these knew prop[...]
