► I first propose a novel approach for sparse coding that further improves upon the sparse representation-based classification (SRC) framework. This proposed framework, affine constrained group… (more)

▼ I first propose a novel approach for sparse coding that further improves upon the sparse representation-based classification (SRC) framework. This proposed framework, affine constrained group sparse coding, extends the current SRC framework to classification problems with multiple inputs. Geometrically, the constrained group sparse coding essentially searches for the vector in the convex hull spanned by the input vectors that can best be sparse coded using the given dictionary. The resulting objective function is still convex and can be efficiently optimized using iterative block-coordinate descend scheme that is guaranteed to converge. Furthermore, I provide a form of sparse recovery result that guarantees, at least theoretically, that the classification performance of the constrained group sparse coding should be at least as good as the group sparse coding. While utilizing the affine combination of multiple input test samples can improve the performance of the conventional sparse representation-based classification framework, it is difficult to integrate this approach into a dictionary learning framework. Therefore, we propose to combine (1) imposing group structure on data (2) imposing block structure on the dictionary and (3) using different regularizer term to sparsely encode the data. We call this approach either block/group (BGSC) or reconstructed block/group (R-BGSC) sparse coding . Incorporating either one of them with the novel Intra-block Coherence Suppression Dictionary Learning (ICS-DL), which, as the name suggests, suppress the coherence of atoms within the same block, algorithm results in a novel dictionary learning framework. An important and distinguishing feature of the proposed framework is that all dictionary blocks are trained simultaneously with respect to each data group while the intra-block coherence being explicitly minimized as an important objective. We provide both empirical evidence and heuristic support for this feature that can be considered as a direct consequence of incorporating both the group structure for the input data and the block structure for the dictionary in the learning process. The optimization problems for both the dictionary learning and sparse coding can be solved efficiently using block-coordinate descent, and the details of the optimization algorithms are presented. In both parts of this work, the proposed methods are evaluated on several classification (supervised) and clustering (unsupervised) problems using well-known datasets. Favorable comparisons with state-of-the-art methods demonstrate the viability and validity of the proposed frameworks.

▼ The finite element method (FEM) is a widely used numerical technique for solution of boundary value problems arising in engineering applications. FEM is well studied and has several advantages; however the stress and strain solutions obtained by FEM are discontinuous across element boundaries and require smoothing algorithms to make the stress/strain appear smooth in the analysis domain. Automatic mesh generation is still a difficult task in FEM for complicated geometries and often requires user intervention for generating quality meshes. Finite elements based on uniform B-spline basis functions defined on a structured grid are developed which provide at least continuous solution through out the analysis domain. Numerical techniques are presented in this work based on structured grids and implicit equations of the boundaries of analysis domain, material interface boundaries or coarse/fine grid interfaces for solution of various engineering boundary value problems. Solution structures are constructed using approximate Heaviside step functions for imposition of Dirichlet boundary conditions, treatment of material discontinuity to perform micromechanical analysis and for local refinement of grid. The use of structured grid eliminates the need for constructing a conforming mesh and results in significant savings of time in pre-processing stage of the design cycle. Numerical examples are presented to demonstrate the performance of B-spline elements. The results are compared with analytical solutions as well as traditional finite element solutions to demonstrate the ability of B-spline elements to represent continuous stress and strain through out analysis domain. Convergence studies show that B-spline elements can provide accurate solutions for many engineering problems with fewer numbers of elements and nodes as compared to traditional FEM. Solution structure for treatment of material boundary is validated by performing a convergence analysis on a problem involving circular inclusion in a square matrix and by determining effective properties of fiber reinforced composite. Solution structure for local grid refinement is validated by analyzing classical stress concentration problems. ( en ) Advisors/Committee Members: Kumar, Ashok V.

▼ Singular value decomposition is a problem that is used in a wide variety of applications like latent semantic indexing, collaborative filtering and gene expression analysis. In this study, we consider the singular value decomposition problem for band and sparse matrices. Linear algebraic algorithms for modern computer architectures are designed to extract maximum performance by exploiting modern memory hierarchies, even though this can sometimes lead to algorithms with higher memory requirements and more floating point operations. We propose blocked algorithms for sparse and band bidiagonal reduction. The blocked algorithms are designed to exploit the memory hierarchy, but they perform nearly the same number of floating point operations as the non-blocked algorithms. We introduce efficient blocked band reduction algorithms that utilize the cache correctly and perform better than competing methods in terms of the number of floating point operations and the amount of required workspace. Our band reduction methods are several times faster than existing methods. The theory and algorithms for sparse singular value decomposition, especially algorithms for reducing a sparse upper triangular matrix to a bidiagonal matrix are proposed here. The bidiagonal reduction algorithms use a dynamic blocking method to reduce more than one entry at a time. They limit the sub-diagonal fill to one scalar by pipelining the blocked plane rotations. A symbolic factorization algorithm for computing the time and memory requirements for the bidiagonal reduction of a sparse matrix helps the numerical reduction step. Our sparse singular value decomposition algorithm computes all the singular values at the same amount of time it takes to compute a few singular values using existing methods. It performs much faster than existing methods when more singular values are required. The features of the software implementing the band and sparse bidiagonal reduction algorithms are also presented.

▼ Wear prediction on the components of a mechanical system without considering the system as a whole will, in most cases, lead to inaccurate predictions. This is because the wear is directly affected by the system dynamics which evolves simultaneously with the wear. In addition, the contact condition (regions of contact for the wearing bodies) also depends on the system dynamics and, in most cases, can only be determined in a multibody dynamics framework. In this work, a procedure to analyze planar multibody systems in which wear is present at one or more revolute joints is presented. The analysis involves modeling multibody systems with revolute joints that consist of clearance. Wear can then be incorporated into the system dynamic analysis by allowing the size and shape of the clearance to evolve as dictated by wear. An iterative wear prediction procedure based on the Archard's wear model is used to compute the wear as a function of the evolving dynamics and tribological data. In this framework, two procedures for the analysis of planar multibody systems with joint wear are developed. In the first procedure contact force at the concerned joint is determined using a contact force law and the wear prediction is based on the finite element method. In the second procedure, contact force determination and the wear prediction are based on the elastic foundation model. The two procedures are validated by comparing the wear predictions with wear on an experimental slider-crank mechanism. The experimental slider-crank is also used as a reference to assess the performance of the two models. It turns out that the procedure based on the finite element method provides reasonably accurate predictions for both wear profile and wear volume/mass whereas the procedure based on the elastic foundation model provides reasonably accurate estimates on the wear volume/mass, is computationally faster but provides progressively poor estimates on the wear profile. Finally an example is presented to illustrate an application of the procedures. In the example, a slide-crank mechanism is designed so that the maximum allowable wear depth at two joints occurs simultaneously.

▼ Training interpersonal skills requires availability, standardization, and diversity of practice interpersonal scenarios. To meet these requirements, we proposed a concept for an interpersonal simulator with a natural interface. We implemented a proof-of concept, called the IPS. We demonstrated that the IPS elicited user performance that was indicative of real world interpersonal skills, making the IPS a powerful tool for interpersonal skills education. To do this, we collaborated with healthcare educators to construct an interpersonal skills training experience using the IPS, called the VOSCE. The VOSCE simulated a patient encounter, and provided feedback on user performance. By conducting pilot studies with the VOSCE, we assessed and improved the usability and acceptability of the IPS for interpersonal skills training. Next, we demonstrated the validity of the VOSCE. An experiment was conducted, which compared user performance in the VOSCE to user performance in a similar real-life interaction. Results showed that performance was significantly correlated, implying that the VOSCE was a valid interpersonal skills evaluation tool. Finally, we demonstrated that changes to the natural interface of the IPS influenced user performance. A significant component of the IPS was the visual display. To provide insight into how changing the visual display component affected interaction with a virtual human, we designed two comparative user studies. The first study compared two immersive visual displays ? a large-screen projection display and a more immersive head-mounted display. Results suggested that higher immersion may impair users? ability to accurately reflect upon their own performance. Participants in the head-mounted display condition were less accurate in evaluating their use of empathy. Following up on results from the first study, the second study compared two non immersive visual displays?a plasma television and a smaller computer monitor. Results suggested that displays that enable life-size scale virtual humans enhance user performance. Participants in the plasma television condition were more engaged, empathetic, pleasant, and natural. ( en ) Advisors/Committee Members: Lok, Benjamin C. (committee chair), Fishwick, Paul A.

▼ In most engineering fields, numerical simulators are used to model complex phenomena and obtain high-fidelity analysis. Despite the growth of computer capabilities, such simulators are limited by their computational cost. Surrogate modeling is a popular method to limit the computational expense. It consists of replacing the expensive model by a simpler model (surrogate) fitted to a few chosen simulations at a set of points called a design of experiments (DoE). By definition, a surrogate model contains uncertainties, since it is an approximation to an unknown function. A surrogate inherits uncertainties from two main sources: uncertainty in the observations (when they are noisy), and uncertainty due to finite sample. One of the major challenges in surrogate modeling consists of controlling and compensating for these uncertainties. Two classical frameworks of surrogate application are used as a discussion thread for this research: constrained optimization and reliability analysis. In this work, we propose alternatives to compensate for the surrogate model errors in order to obtain safe predictions with minimal impact on the accuracy. The methods are based on different error estimation techniques, some based on statistical assumptions and some that are non-parametric. Their efficiency are analyzed for general prediction and for the approximation of reliability measures. We also propose two contributions to the field of design of experiments in order to minimize the uncertainty of surrogate models. Firstly, we address the issue of choosing the experiments when surrogates are used for reliability assessment and constrained optimization. Secondly, we propose global sampling strategies to answer the issue of allocating limited computational resource in the context of RBDO. All methods are supported by quantitative results on simple numerical examples and engineering applications. ( en ) Advisors/Committee Members: Haftka, Raphael T.
