Visualizing Uncertainty And Qualifier For Bayesian Decision Making written by Dapeng Cao and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2013 with categories.

Probabilistic decision-making is ubiquitously present in medical diagnosis, intelligence analysis, weather forecasting, and other command and control domains. People often rely on incomplete and uncertain information to make high-stake decisions in such complex domains. For example medical diagnostic tests have varying levels of sensitivity and specificity, indicating the chances of missing a diagnoses or falsely diagnosing an illness. An informed diagnostic decision should combine prior knowledge about a disease (e. g. base rate) with new evidence such as test result. A history of previous research shows that people generally do not function well at combining and reasoning about such probabilities. The goal of this research was to develop and to evaluate a novel visualization method for representing uncertainty and its qualifiers in single- and multi-step Bayesian reasoning. The visualization method was instantiated in an interactive software tool, which visualizes prior and posterior probabilities with colors and shapes. Qualifiers of uncertainty (e. g. range of uncertainty, overlapping uncertainty) are further represented with graphical variables such as color saturation and semi-transparency. An experiment tested the effectiveness of the visual representation by asking 60 participants to answer 28 questions regarding six Bayesian reasoning scenarios. The results show significant performance advantage in participants' response accuracy for the two improved display formats augmented by the visualization method in static screenshots or in interactive software. The performance advantage was present across all domains tested and among participants with diverse levels of prior statistical knowledge. It is also evident that the visualization method can reduce participants' subjective workload and mitigate the adverse effect of increasing complexity in the Bayesian reasoning scenarios. The development of a novel visualization method and evaluation scheme, and the knowledge gained from the experiment, has demonstrated a good potential in contributing to future implementations of visualized Bayesian decision-support for practitioners in medical diagnosis and possibly other command and control domains. The visualization method and the software could also benefit the general public by promoting broader understanding and applications of Bayesian decision-making. This study provides a necessary step towards a range of future researches in visualized Bayesian reasoning and in uncertainty visualization for decision-making.

II Challenges in Data Mapping Part II deals with one of the most challenging tasks in Interactive Visualization, mapping and teasing out information from large complex datasets and generating visual representations. This section consists of four chapters. Binh Pham, Alex Streit, and Ross Brown provide a comprehensive requirement analysis of information uncertainty visualizations. They examine the sources of uncertainty, review aspects of its complexity, introduce typical models of uncertainty, and analyze major issues in visualization of uncertainty, from various user and task perspectives. Alfred Inselberg examines challenges in the multivariate data analysis. He explains how relations among multiple variables can be mapped uniquely into ?-space subsets having geometrical properties and introduces Parallel Coordinates meth- ology for the unambiguous visualization and exploration of a multidimensional geometry and multivariate relations. Christiaan Gribble describes two alternative approaches to interactive particle visualization: one targeting desktop systems equipped with programmable graphics hardware and the other targeting moderately sized multicore systems using pack- based ray tracing. Finally, Christof Rezk Salama reviews state-of-the-art strategies for the assignment of visual parameters in scientific visualization systems. He explains the process of mapping abstract data values into visual based on transfer functions, clarifies the terms of pre- and postclassification, and introduces the state-of-the-art user int- faces for the design of transfer functions.

This book presents a collection of selected papers that represent the current variety of research on the teaching and learning of probability. The respective chapters address a diverse range of theoretical, empirical and practical aspects underpinning the teaching and learning of probability, curricular issues, probabilistic reasoning, misconceptions and biases, as well as their pedagogical implications. These chapters are divided into THREE main sections, dealing with: TEACHING PROBABILITY, STUDENTS' REASONING AND LEARNING AND EDUCATION OF TEACHERS. In brief, the papers presented here include research dealing with teachers and students at different levels and ages (from primary school to university) and address epistemological and curricular analysis, as well as the role of technology, simulations, language and visualisation in teaching and learning probability. As such, it offers essential information for teachers, researchers and curricular designers alike.

Modern Mathematics is constructed rigorously through proofs, based on truths, which are either axioms or previously proven theorems. Thus, it is par excellence a model of rational inquiry. Links between Cognitive Psychology and Mathematics Education have been particularly strong during the last decades. Indeed, the Enlightenment view of the rational human mind that reasons, makes decisions and solves problems based on logic and probabilities, was shaken during the second half of the twentieth century. Cognitive psychologists discovered that humans' thoughts and actions often deviate from rules imposed by strict normative theories of inference. Yet, these deviations should not be called "errors": as Cognitive Psychologists have demonstrated, these deviations may be either valid heuristics that succeed in the environments in which humans have evolved, or biases that are caused by a lack of adaptation to abstract information formats. Humans, as the cognitive psychologist and economist Herbert Simon claimed, do not usually optimize, but rather satisfice, even when solving problem. This Research Topic aims at demonstrating that these insights have had a decisive impact on Mathematics Education. We want to stress that we are concerned with the view of bounded rationality that is different from the one espoused by the heuristics-and-biases program. In Simon’s bounded rationality and its direct descendant ecological rationality, rationality is understood in terms of cognitive success in the world (correspondence) rather than in terms of conformity to content-free norms of coherence (e.g., transitivity).
