DISTURBANCE OF STATISTICAL STABILITY (PART II)
By: Igor Gorban  (2787 reads)
Rating: (1.00/10)

Abstract: The revue of results obtained by the author this year in the area of disturbance of statistical stability of physical quantities and processes is presented. Two new sensitive parameters characterizing their statistical instability in finite observation interval are proposed. For known and new parameters of statistical instability unit measures that give possibility to characterize the level of disturbance are introduced. It is shown by modeling that STD corridors of unit measures weakly depend from the type of the distribution. It is confirmed that important role in disturbance of statistical stability plays specific fluctuation of expectation of the process that generates changes of average expectation. Dependence of parameters of statistical instability from normalized sample variance of expectation average is found. It is shown by modeling that positive correlation calls increasing of statistical instability and negative correlation – decreasing of it. Under any type correlation increasing of sample size calls increasing of statistical stability and the process trends to statistically stable state. It is found that changes of variance influence to statistical stability of the process. Under some relations of parameters unpredictable component of the process fades-out and under other ones – fades-in. It is demonstrated high sensitivity of new parameter of statistical instability. It is shown that fluctuations of maximum day temperature and minimum day temperature in two cities (Moscow and Kiev) are instable and fluctuation of day precipitation is near stable. Disturbance of statistical stability of temperature begins from some observation weeks.

Rating: (1.00/10)

Abstract: This study explores and compares predictive abilities of six types of neural networks used as tools for computer-aided breast cancer diagnosis, namely, multilayer perceptron, cascade-correlation neural network, and four ART-based neural networks. Our experimental dataset consists of 803 patterns of 39 BI-RADS, mammographic, sonographic, and other descriptors. Using such a combination of features is not traditional in the field and we find it is better than traditional ones. The study also focuses on exploring how various feature selection techniques influence predictive abilities of the models. We found that certain feature subsets show themselves as top candidates for all the models, but each model performs differently with them. We estimated models performance by ROC analysis and metrics, such as max accuracy, area under the ROC curve, area under the convex hull, partial area under the ROC curve with sensitivity above 90%, and specificity at 98% sensitivity. We paid particular attention to the metrics with higher specificity as it reduces false positive predictions, which would allow decreasing unnecessary benign breast biopsies while minimizing the number of delayed breast cancer diagnoses. In order to validate our experiments we used 5-fold cross validation. In conclusion, out results show that among the neural networks considered here, best overall performer is the Default ARTMAP neural network.

Rating: (1.00/10)

Abstract: With steadily evolving new paradigms for technology enhanced learning, educational word games such as quizzes, puzzles and quests raise new appeal and motivation for students in following game based educational processes. Traditional word games may be applied more successfully to game based learning in given scientific domain provided they are highly oriented to the content and problems of that domain. Such games may be more efficient if they include artificial agents simulating opponents, advisors or collaborators of the player. Authors present a semantic structuring model of learning content for logic and word games serving for educational purposes and, next, show the place of artificial agents within the game construction and possible ways of agent’s realization. There are given results from practical experiments with playing a memory game using the semantic content model, without and with agents integrated into the game.

TACTICAL MANAGEMENT OF SUPPLY CHAIN WITH AGENT BASED MODELING AND SIMULATION

Rating: (1.00/10)

Abstract: Excellence in Supply Chain Management depends on timely and effective translation of market demand into material and products control decisions across Supply Chain. As has been observed many times, this task may be complicated by several technical and business related constraints. Effective decision making processes are essential to execute Supply Chain in such a way that products will be made at lowest possible cost and delivered on time. In most cases, software support has to be used. Supply Chain related decisions are usually poorly structured and therefore only reasonable way to support them is to use simulation tools. The main aim of the paper is to show how Supply Chain Management process can be supported with Agent Oriented Simulation Platform. The case study presented describes in detail the decision situation that is analyzed from scratch, by simulating different scenarios for suggested problem solutions. Finally the paper shows how the analysis of simulation results may lead to final decision solving the problems encountered.

Rating: (1.00/10)

Abstract: In this paper we propose a modelling technique for the control of computational processes. The Petri Net model, particularly a Timed Event Graph (TEG) can be used for analyzing. The proposed model enables the determination of state equations. The max-plus algebra represents linear algebraic form of discrete systems and supplies new tools to their modelling. We develop a linear mathematical model under constraints in the Max-plus algebra. When using max-plus algebra with TEG, the arc weights are kept equal to one in order to be able to resolve the state equations. Structure of max-plus algebra is equipped with maximization and addition operations over of the real numbers and minus infinity. It can be used appropriately to determine marking times within a given Petri net and a vector filled with marking state at the beginning. Tools of max-plus algebra are useful to investigate properties of network models. Finally, numerical examples show the use of this model.

Rating: (1.00/10)

Abstract: RICHE (Research Inventory of Child Health in Europe) is a platform developed and funded under the Health domain of 7th European Framework Program. The platform search engine is expected to use the multilingual taxonomy of terms for processing and classifying large volumes of documents of the RICHE repository. So far the experts participating in this project have produced the initial version of expert based taxonomy of terms relating to child health (based on existing taxonomies). In the paper we propose a simple man-machine technique for continuous support and development of the existing term list, which consists of three steps: 1) construction of various keyword lists extracted from a topic oriented document set using various levels of word specificity 2) selection of the most useful keyword lists using subjective criteria as a precision of selection and a number of new words 3) manual selection of new terms. Experimental material was represented by documents uploaded from three organizations active in child health improvement policies: World Bank, World Health Organization (WHO), and DG SANCO of European Commission (EC). The selection was performed in order to assess terms used in these documents that may be absent in the RICHE taxonomy. Presented work should be considered as a pilot (feasibility) study. The objective of the RICHE platform is to identify gaps in European child health research, so extensive mapping exercise has been started. Classification of identified studies is essential and cannot be based only on traditional terms of existing taxonomies. Emergent terms (such as for example “cyberbullying”) need to be identified and included into existing taxonomies. In our future work we focus on developing techniques related to multilevel and multiword term selection

Abstract: In this paper, we show how to represent to our formal reasoning and to model social context as knowledge using network models to aggregate heterogeneous information. We show how social context can be efficiently used for well understood tasks in natural language processing (such as context-dependent automated, large scale semantic annotation, term disambiguation, search of similar documents), as well as for novel applications such as social recommender systems which aim to alleviate information overload for social media users by presenting the most attractive and relevant content. We present the algorithms and the architecture of a hybrid recommender system in the activity centric environment Nepomuk-Simple?
