PPT-Modeling the Uncertainty Due to Data/Visual Transformations using Sensitivity Analysis

This project proposes to study sensitivity analysis for guiding the evaluation of uncertainty of data in the visual analytics process We aim to achieve Semiautomatic Extraction of Sensitivity Information. 1 2D Transformations Given a point cloud polygon or sampled parametric curve w e can use transformations for several purposes 1 Change coordinate frames world window viewport devic e etc 2 Compose objects of simple parts with local scaleposition orie Jake Blanchard. Spring 2010. Uncertainty Analysis for Engineers. 1. Introduction. We’ve discussed single-variable probability distributions. This lets us represent uncertain inputs. But what of variables that depend on these inputs? How do we represent their uncertainty?. Ch. 2 Lesson 3. Pg. 123. What will you will learn?. Enlarge Photographs. Make something from a pattern. Identify Similarity. Two figures are . similar. if the second can be obtained from the first by a sequence of transformations and dilations. 1. Sensitivity Analysis. Basic theory.

Transformation: a transformation is a change in position, shape or size.. Graph: .  . What is the parent function for this graph?. What does the parent function look like?. Shape is a V. Vertex is (0, 0). Slope is 1, opens up. How is the graph above different from the parent function?. Objective. The Los Alamos Sea Ice model has a number of input parameters for which accurate values are not always well established. . We conduct a variance-based sensitivity analysis . of hemispheric sea ice properties to 39 input parameters. The method accounts for non-linear and non-additive effects in the model.. CSE 455.
