Sensitivity Analysis and Monte Carlo Simulation
When you are working with large and complex Simulink models, it is sometimes difficult to determine which model parameters impact behavior the most. Using Monte Carlo simulations, correlation techniques and design of experiments (DoE), Sensitivity Analysis allows you to determine which parameters have the greatest impact on your model.

Using Monte Carlo simulations, correlation techniques and design of experiments (DoE), Sensitivity Analysis allows you to determine which parameters have the greatest impact on your model. In this webinar, we will use an example to demonstrate how to analyze and visualize your model's behavior across its design space using Monte Carlo simulations. This will help you identify which parameters impact characteristics such as step response times, energy consumption and component failure rates. You can also use sensitivity analysis to improve design optimization performance. Using an example, we will see how you can identify a good initial point and a smaller set of parameters in a large model, allowing you to reduce the time taken for the optimization process.

Global Sensitivity Analysis - Saman Razavi
The JRC's Sensitivity Analysis group (SAMO) presents "A New Framework for Comprehensive, Efficient, and Robust Global Sensitivity Analysis", by Saman Razavi, University of Saskatchewan. Seminar at the European Commision Joint Research Centre (JRC) – Ispra – 2 May 2017. This presentation provides an overview of the theory and application of a new framework for Global Sensitivity Analysis (GSA), called Variogram Analysis of Response Surfaces (VARS). VARS utilizes the concepts of variograms and covariograms to characterize a spectrum of sensitivity-related information across the model factor space. VARS is a general framework with explicit theoretical relationships with variance-based (e.g., Sobol) and derivative-based (e.g, Morris) approaches to GSA, while being highly efficient and statistically robust. This presentation also discusses strategies for improved convergence and robustness of GSA, and to this end, introduces a sequential sampling algorithm, called Progressive Latin Hypercube Sampling (PLHS), which allows progressively increasing the sample size, while maintaining the required distributional properties. Saman Razavi received his PhD degree (2013) in civil engineering from the University of Waterloo, Ontario, and his MSc (2004) and BSc (2002) degrees in civil engineering from Amirkabir University and Iran University of Science and Technology in Iran. His research interests include environmental and water resources systems analysis, hydrologic modelling, single and multiple-objective optimization, sensitivity and uncertainty analysis, and climate change and impacts on hydrology and water resources.

Machine Learning, Classification and Algorithms using MATLAB: Learn to Implement Classification Algorithms In One of the Most Power Tool used by Scientists and Engineer. This course is designed to cover one of the most interesting areas of machine learning called classification. I will take you step-by-step in this course and will first cover the basics of MATLAB. Following that we will look into the details of how to use different machine learning algorithms using MATLAB. Specifically, we will be looking at the MATLAB toolbox called statistic and machine learning toolbox.We will implement some of the most commonly used classification algorithms such as K-Nearest Neighbor, Naive Bayes, Discriminant Analysis, Decision Tress, Support Vector Machines, Error Correcting Output Codes and Ensembles. Following that we will be looking at how to cross validate these models and how to evaluate their performances. Intuition into the classification algorithms is also included so that a person with no mathematical background can still comprehend the essential ideas. The following are the course outlines. Segment 1: Grabbing and Importing Dataset + Segment 2: K-Nearest Neighbor + Segment 3: Naive Bayes + Segment 4: Decision Trees + Segment 5: Discriminant Analysis + Segment 6: Support Vector Machines + Segment 7: Error Correcting Output Codes + Segment 8: Classification with Ensembles + Segment 9: Validation Methods + Segment 10: Evaluating Performance.

Global Sensitivity Analysis: Variogram Analysis of Response Surfaces (VARS)
Dr. Saman Razavi speaks about the fundamentals of global sensitivity analysis (GSA) and VARS, which is a new mathematical framework for GSA of computer simulation models, including Earth and Environmental Systems Models (EESMs). VARS, which stands for Variogram Analysis of Response Surfaces, utilizes directional variogram and covariogram functions to characterize the full spectrum of sensitivity-related information, thereby providing a comprehensive set of "global" sensitivity metrics with minimal computational cost. See more on VARS in http://homepage.usask.ca/~ser134/nex_gen_sen_an.php Dr. Saman Razavi leads Watershed Systems Analysis and Modelling Lab at the Global Institute for Water Security. He is an assistant professor with School of Environment and Sustainability and Department of Civil and Geological Engineering at the University of Saskatchewan. He received the PhD degree (2013) in civil engineering from the University of Waterloo, Ontario, and the MSc (2004) and BSc (2002) degrees in civil engineering from Amirkabir University and Iran University of Science and Technology in Iran. Dr. Razavi is an Associate Editor of Journal of Hydrology and an Editorial Board Member of Environmental Modelling & Software. He also serves on several international committees. His research interests include environmental and water resources systems analysis, hydrologic modelling, single- and multiple-objective optimization, sensitivity and uncertainty analysis, and climate change and impacts on hydrology and water resources. http://homepage.usask.ca/~ser134/ ________________________________________________________ What is Global Sensitivity Analysis (GSA)? Global sensitivity analysis is a systems theoretic approach to characterizing the overall (average) sensitivity of one or more model responses across the factor space, by attributing the variability of those responses to different controlling (but uncertain) factors (e.g., model parameters, forcings, and boundary and initial conditions). ________________________________________________________ What was the Motivation for the Development of VARS? VARS was developed to address two major issues with GSA: · Ambiguous Definition of "Global" Sensitivity: different GSA methods are based in different philosophies and theoretical definitions of sensitivity, leading to different, even conflicting, assessments of the underlying sensitivities for a given problem. · Computational Cost: the cost of carrying out GSA can be large, even excessive, for high-dimensional problems and/or computationally intensive models, where cost (or "efficiency") is commonly assessed by of the number of required model runs. ________________________________________________________ What are the Special Features of VARS? · VARS re-defines GSA by characterizing a comprehensive spectrum of information about the underlying sensitivities of a response surface to its factors, while reducing to well-known and commonly used approaches to GSA as special/limiting cases. · VARS generates a new set of sensitivity metrics called IVARS (Integrated Variogram Across a Range of Scales) that summarize the variance of change (rate of variability) in model response at a range of perturbation scales in the factor space. · VARS also generates the Sobol (variance-based) total-order effect, the most popular metric for GSA, and the Morris (derivative-based) elementary effects across the full range of step sizes in numerical differencing (theoretical relationship exists). · VARS is highly efficient and statistically robust, providing stable results within 1-2 orders of magnitude smaller numbers of sampled points (model runs), compared with alternative GSA approaches, such as the Sobol and Morris approaches. · VARS effectively and efficiently handles high-dimensional problems, because of its computational efficiency, which is, in part, due to VARS being based on the information contained in pairs of points, rather than in individual points. · VARS is unique in that it characterizes different sensitivity-related properties of response surfaces including local sensitivities and their global distribution, the global distribution of model responses, and the structure of the response surface. · VARS tackles the scale issue of sensitivity analysis by providing sensitivity information spanning a range of scales across the factor space, from small-scale features such as roughness/noise to large-scale features such as multimodality.
