Opis:
In this paper we present a new approach to data analysis based on flow distribution study in a flow network. Branches of the flow graph are interpreted as decision rules, whereas the flow graph is supposed to describe a decision algorithm. We propose to model decision processes as flow graphs and analyze decisions in terms of flow spreading in the graph.

Opis:
W pierwszych dwóch rozdziałach analizujemy za pomocą metody skalowania wielowymiarowego i metody skalowania wielowymiarowego różnic indywidualnych pewien praktyczny przykład, a w trzecim rozdziale - dla porównania - przedstawiamy wyniki analizy tego samego przykładu za pomocą hierarchicznej analizy skupień.
Several methods of multidimensional scaling are first reviewed. The emphasis is not on mathematical intricacies of estimating techniques but on general formulation of the problem itself. A practical example is analyzed by means of multidimensional scaling and individual differences scaling methods. In the last chapter the same example is investigated for comparative reasons using hierarchical cluster analysis.

Opis:
Visual data analysis is an appealing and increasing field of application. We present two related visual analysis approaches that allow for the visualization of graphical model parameters and time-dependent association rules. When the graphical model is defined over purely nominal attributes, its local structure can be interpreted as an association rule. Such association rules comprise one of the most prominent and wide-spread analysis techniques for pattern detection, however, there are only few visualization methods. We introduce an alternative visual representation that also incorporates time since patterns are likely to change over time when the underlying data was collected from real-world processes. We apply the technique to both an artificial and a complex real-life dataset and show that the combined automatic and visual approach gives more and faster insight into the data than a fully-automatic approach only. Thus, our proposed method is capable of reducing considerably the analysis time.

Opis:
Purpose: Presentation of selected methods of project and data analysis - describes how data on ongoing projects should be collected, so that it can be used later, by applying the appropriate methodology. Design/methodology/approach: Literature research of the subject was carried out. Finding: Having a methodology for data collection leads, in the long term, to the implementation of a system that allows the use of this methodology. The system should provide information to help make better decisions, reducing or eliminating the risk of project failure. Practical implications: Development of a methodology of data collection and analysis on this basis. Originality/value: The implemented projects are comparable with each other and, on this basis, it can be argued that identifying the risks that have occurred in the past, during the implementation of various stages of projects, can contribute to more effective risk management during the implementation of current and future projects.

Opis:
The main directions of digitalization of the education system are considered, the infrastructural and technological aspect of new strategic directions of development is analyzed. The author analyzed information systems and services in education, taking into account the possibility of using technologies for analytical data processing. The problem of using data analytics tools in education at present is the lack of uniform formats and tools for integrating information systems. Data in education accumulates in various solutions that do not share the results of the educational process. Based on this, it is impossible to build a clear system of end-to-end interaction between systems on common platforms. The author aims to solve this problem by modeling an integrated solution for data analysis at all levels of education. The article proposes technical and organizational solutions for the creation of integrated analytics services that allow accumulating and transmitting data on educational results during the transition of a student between learning levels. The analysis tools are based on the use of big data technologies.

Opis:
The paper presents methodologies associated with visualization, which supports data analysis. Analyzed data has been gathered by HoneyPot systems deployed in the network of Institute of Computer Science. Due to the vast amounts of data, the manual analysis was almost impossible and very impractical, also considering time constraints. Introduced visualization techniques and supporting filtering features are implemented in HPMS (HoneyPot Management System). The paper describes in details two introduced methodologies which support data analysis using both charts and graphs. The first one is used for the discovery of basic activities observed by HoneyPot. The second one is used for advanced analysis of machines used during attacks concerning PhpMyAdmin software.

Opis:
This paper focuses on practical aspects of gigabit passive optical networks (GPON) diagnostics during deployment, for root-cause analysis and for research purposes. While GPON signalling analysis is already quite commonly used for diagnostics, the aim of this work is a holistic approach, including both signalling and user plane (payload) analysis. User plane analysis, especially if targeted at payload Ethernet, IP and transport layers, enables detection of additional group of problems that could limit or even prevent GPON internetworking and thus degrade the user perceived service quality. Integrated signalling and payload analysis is also interesting from the research point of view, leading to the ability to study equipment idiosyncrasies that would be hard to detect otherwise and it is also one of the enablers of equipment security verification. The mentioned theories were tested during a practical diagnostic session on a real GPON network deployment and this paper presents the findings.
