The Affordances Of Process-Tracing Technologies For Supporting L2 Writing Instruction, Jim R. Ranalli, Hui-Hsien Feng, Evgeny Chukharev-Khudilaynen Jan 2018

The Affordances Of Process-Tracing Technologies For Supporting L2 Writing Instruction, Jim R. Ranalli, Hui-Hsien Feng, Evgeny Chukharev-Khudilaynen

English Publications

The research literature on L2 writing processes contains a multitude of insights that could inform writing instruction, but writing teachers are constrained in their capacity to make use of these insights insofar as they lack detailed information about how their students’ actually engage in the processes of writing. At the same time, writing-process researchers have been using powerful technologies to trace writers’ process engagement—namely, keystroke-logging and eye-tracking—that are potentially applicable in educational settings. In this article, we describe a pilot effort to integrate these technologies into L2 writing instruction with college-level ESL students. In addition to illustrating three ...

Rapid Tagging And Reporting For Functional Language Extraction In Scientific Articles, Mahdi Ramezani, Vijay K. Kalivarapu, Stephen B. Gilbert, Sarah R. Huffman, Elena Cotos, Annette M. O'Connor

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This paper describes the development of a web-based application for tagging scientific articles, in part to create machine learning training datasets for automated functional language identification and extraction (AFLEX). The initial intent for this work was to provide a new member of the ecosystem of tools that facilitate the structured automation of systematic reviews, an area of work that typically requires critical analysis of multiple research studies and provides an exhaustive summary of literature related to a research question. However, the tool’s modular interface allows use across disciplines. A user may upload PDF or text documents and quickly tag ...


Iteration Complexity Analysis Of Block Coordinate Descent Methods, Mingyi Hong, Xiangfeng Wang, Mesiam Razaviyayn, Zhi-Quan Luo Aug 2016

Iteration Complexity Analysis Of Block Coordinate Descent Methods, Mingyi Hong, Xiangfeng Wang, Mesiam Razaviyayn, Zhi-Quan Luo

Industrial and Manufacturing Systems Engineering Publications

In this paper, we provide a unified iteration complexity analysis for a family of general block coordinate descent methods, covering popular methods such as the block coordinate gradient descent and the block coordinate proximal gradient, under various different coordinate update rules. We unify these algorithms under the so-called block successive upper-bound minimization (BSUM) framework, and show that for a broad class of multi-block nonsmooth convex problems, all algorithms covered by the BSUM framework achieve a global sublinear iteration complexity of O(1/r)" role="presentation" style="box-sizing: border-box; display: inline-table; line-height: normal; letter-spacing: normal; word-spacing: normal; word-wrap: normal; white-space: nowrap ...


On The Linear Convergence Of The Alternating Direction Method Of Multipliers, Mingyi Hong, Zhi-Quan Luo Jul 2016

On The Linear Convergence Of The Alternating Direction Method Of Multipliers, Mingyi Hong, Zhi-Quan Luo

Industrial and Manufacturing Systems Engineering Publications

We analyze the convergence rate of the alternating direction method of multipliers (ADMM) for minimizing the sum of two or more nonsmooth convex separable functions subject to linear constraints. Previous analysis of the ADMM typically assumes that the objective function is the sum of only two convex functions defined on two separable blocks of variables even though the algorithm works well in numerical experiments for three or more blocks. Moreover, there has been no rate of convergence analysis for the ADMM without strong convexity in the objective function. In this paper we establish the global R-linear convergence of the ADMM ...


Alternating Direction Method Of Multipliers For Penalized Zero-Variance Discriminant Analysis, Brendan P.W. Ames, Mingyi Hong Feb 2016

Alternating Direction Method Of Multipliers For Penalized Zero-Variance Discriminant Analysis, Brendan P.W. Ames, Mingyi Hong

Industrial and Manufacturing Systems Engineering Publications

We consider the task of classification in the high dimensional setting where the number of features of the given data is significantly greater than the number of observations. To accomplish this task, we propose a heuristic, called sparse zero-variance discriminant analysis, for simultaneously performing linear discriminant analysis and feature selection on high dimensional data. This method combines classical zero-variance discriminant analysis, where discriminant vectors are identified in the null space of the sample within-class covariance matrix, with penalization applied to induce sparse structures in the resulting vectors. To approximately solve the resulting nonconvex problem, we develop a simple algorithm based ...

Sinr Constrained Beamforming For A Mimo Multi-User Downlink System: Algorithms And Convergence Analysis, Oingjang Shi, Meisam Razaviyayn, Mingyi Hong, Zhi-Quan Luo Jan 2016

Sinr Constrained Beamforming For A Mimo Multi-User Downlink System: Algorithms And Convergence Analysis, Oingjang Shi, Meisam Razaviyayn, Mingyi Hong, Zhi-Quan Luo

Industrial and Manufacturing Systems Engineering Publications

Consider a multiple-input multiple-output (MIMO) downlink multi-user channel. A well-studied problem in such a system is the design of linear beamformers for power minimization with the quality of service (QoS) constraints. The most representative algorithms for solving this class of problems are the so-called minimum mean square error (MMSE)-second-order cone programming (SOCP) algorithm [Visotksy and Madhow, “Optimum Beamforming Using Transmit Antenna Arrays,” Proc. IEEE Veh. Technol. Conf., May 1999, vol. 1, pp. 851-856] , [Wong, Zheng, and Ng, “Convergence Analysis of Downlink MIMO Antenna System Using Second-Order Cone Programming,” Proc. 62nd IEEE Veh. Technol. Conf., Sep. 2005, pp. 492-496] and ...


Asynchronous Distributed Admm For Large-Scale Optimization—Part I: Algorithm And Convergence Analysis, Tsung-Hui Chang, Mingyi Hong, Wei-Cheng Liao, Xiangfeng Wang Jan 2016

Asynchronous Distributed Admm For Large-Scale Optimization—Part I: Algorithm And Convergence Analysis, Tsung-Hui Chang, Mingyi Hong, Wei-Cheng Liao, Xiangfeng Wang

Industrial and Manufacturing Systems Engineering Publications

Aiming at solving large-scale optimization problems, this paper studies distributed optimization methods based on the alternating direction method of multipliers (ADMM). By formulating the optimization problem as a consensus problem, the ADMM can be used to solve the consensus problem in a fully parallel fashion over a computer network with a star topology. However, traditional synchronized computation does not scale well with the problem size, as the speed of the algorithm is limited by the slowest workers. This is particularly true in a heterogeneous network where the computing nodes experience different computation and communication delays. In this paper, we propose ...


Asynchronous Distributed Admm For Large-Scale Optimization—Part Ii: Linear Convergence Analysis And Numerical Performance, Tsung-Hui Chang, Wei-Cheng Lao, Mingyi Hong, Xiangfeng Wang Jan 2016

Asynchronous Distributed Admm For Large-Scale Optimization—Part Ii: Linear Convergence Analysis And Numerical Performance, Tsung-Hui Chang, Wei-Cheng Lao, Mingyi Hong, Xiangfeng Wang

Industrial and Manufacturing Systems Engineering Publications

The alternating direction method of multipliers (ADMM) has been recognized as a versatile approach for solving modern large-scale machine learning and signal processing problems efficiently. When the data size and/or the problem dimension is large, a distributed version of ADMM can be used, which is capable of distributing the computation load and the data set to a network of computing nodes. Unfortunately, a direct synchronous implementation of such algorithm does not scale well with the problem size, as the algorithm speed is limited by the slowest computing nodes. To address this issue, in a companion paper, we have proposed ...

A Unified Algorithmic Framework For Block-Structured Optimization Involving Big Data: With Applications In Machine Learning And Signal Processing, Mingyi Hong, Meisam Razaviyayn, Zhi-Quan Luo

Industrial and Manufacturing Systems Engineering Publications

This article presents a powerful algorithmic framework for big data optimization, called the block successive upper-bound minimization (BSUM). The BSUM includes as special cases many well-known methods for analyzing massive data sets, such as the block coordinate descent (BCD) method, the convex-concave procedure (CCCP) method, the block coordinate proximal gradient (BCPG) method, the nonnegative matrix factorization (NMF) method, the expectation maximization (EM) method, etc. In this article, various features and properties of the BSUM are discussed from the viewpoint of design flexibility, computational efficiency, parallel/distributed implementation, and the required communication overhead. Illustrative examples from networking, signal processing, and machine ...

Joint Source-Relay Design For Full-Duplex Mimo Af Relay Systems, Qingjiang Shi, Mingyi Hong, Xiqi Gao, Enbin Song, Yunlong Cai, Weiqiang Xu

Industrial and Manufacturing Systems Engineering Publications

The performance of full-duplex (FD) relay systems can be greatly impacted by the self-interference (SI) at relays. By exploiting multiple antennas, the spectral efficiency of FD relay systems can be enhanced through spatial SI mitigation. This paper studies joint source transmit beamforming and relay processing to achieve rate maximization for FD multiple-input-multiple-output (MIMO) amplify-and-forward (AF) relay systems with consideration of relay processing delay. The problem is difficult to solve mainly due to the SI constraint induced by the relay processing delay. In this paper, we first present a sufficient condition under which the relay amplification matrix has rank-one structure. Then ...


Sample Approximation-Based Deflation Approaches For Chance Sinr-Constrained Joint Power And Admission Control, Ya-Feng Liu, Mingyi Hong, Enbin Song Jan 2016

Sample Approximation-Based Deflation Approaches For Chance Sinr-Constrained Joint Power And Admission Control, Ya-Feng Liu, Mingyi Hong, Enbin Song

Industrial and Manufacturing Systems Engineering Publications

Consider the joint power and admission control (JPAC) problem for a multiuser single-input single-output (SISO) interference channel. Most existing works on JPAC assume the perfect instantaneous channel state information (CSI). In this paper, we consider the JPAC problem with the imperfect CSI, i.e., we assume that only the channel distribution information (CDI) is available. We formulate the JPAC problem into a chance (probabilistic)-constrained program, where each link's SINR outage probability is enforced to be less than or equal to a specified tolerance. To circumvent the computational difficulty of the chance SINR constraints, we propose to use the ...

Center for e-Design Publications

Semantic technologies are playing an increasingly popular role as a means for advancing the capabilities of knowledge management systems. Among these advancements, researchers have successfully leveraged semantic technologies, and their accompanying techniques, to improve the representation and search capabilities of knowledge management systems. This paper introduces a further application of semantic techniques. We explore semantic relatedness as a means of facilitating the development of more “intelligent” engineering knowledge management systems. Using semantic relatedness quantifications to analyze and rank concept pairs, this novel approach exploits semantic relationships to help identify key engineering relationships, similar to those leveraged in change management systems ...


An Integrated Approach To Information Modeling For The Sustainable Design Of Products, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden, Paul Witherell, Kemper E. Lewis Jan 2013

An Integrated Approach To Information Modeling For The Sustainable Design Of Products, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden, Paul Witherell, Kemper E. Lewis

Center for e-Design Proceedings

The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support such a process, we propose the development of an environment where sustainability considerations are explicitly introduced early into the design process. This explicitness is provided by integrating the requirements information of sustainability standards and regulations directly into the design process. The emergence of the semantic web provides an interoperable environment in which the context and meaning of knowledge about the relationships among various domains can be ...


A Lower Bound On Proximity Preservation By Space Filling Curves, Pan Xu, Srikanta Tirthapura Jan 2012

A Lower Bound On Proximity Preservation By Space Filling Curves, Pan Xu, Srikanta Tirthapura

Electrical and Computer Engineering Conference Papers, Posters and Presentations

Abstract: A space filling curve (SFC) is a proximity preserving mapping from a high dimensional space to a single dimensional space. SFCs have been used extensively in dealing with multi-dimensional data in parallel computing, scientific computing, and databases. The general goal of an SFC is that points that are close to each other in high-dimensional space are also close to each other in the single dimensional space. While SFCs have been used widely, the extent to which proximity can be preserved by an SFC is not precisely understood yet. We consider natural metrics, including the "nearest-neighbor stretch" of an SFC ...


Support Of Product Innovation With A Modular Framework For Knowledge Management: A Case Study, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden Jan 2011

Support Of Product Innovation With A Modular Framework For Knowledge Management: A Case Study, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

Center for e-Design Proceedings

This paper presents an e-Design framework for knowledge management through its application in an engineering design case study. The e-Design framework enables the implementation of integrated design information throughout the entire design process. It facilitates the ease of sharing real time information across multiple individual designers, departments, or organizations as would be required in large scale design efforts. Similarly, it allows for the ease of use of technical tools integral to the design process that small design departments depend upon. Thus, regardless of the scale, the efficiency of engineering design can be improved with the use of the e-Design framework ...

Towards Industrial Implementation Of Emerging Semantic Technologies, Jay T. Brindel, Ian R. Grosse, Sundar Krishnamurty, John Altidor, Seth Trachtenberg, Paul Witherell

Center for e-Design Proceedings

Every new design, project, or procedure within a company generates a considerable amount of new information and important knowledge. Furthermore, a tremendous amount of legacy knowledge already exists in companies in electronic and non-electronic formats, and techniques are needed for representing, structuring and reusing this knowledge. Many researchers have spent considerable time and effort developing semantic knowledge management systems, which in theory are presumed to address these problems. Despite significant research investments, little has been done to implement these systems within an industrial setting. In this paper we identify five main requirements to the development of an industry-ready application of ...


A Semantic Information Model For Capturing And Communicating Design Decisions, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden Sep 2010

A Semantic Information Model For Capturing And Communicating Design Decisions, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden

Center for e-Design Publications

A semantic information model to improve reuse and communication of engineering design knowledge is presented in this paper. We consider design to be a process involving a sequence of decisions informed by the current state of information. As such, the information model developed is structured to reflect the conceptualizations of engineering design decisions with a particular emphasis on semantically capturing design rationale. Through the approach presented, knowledge reuse is achieved by communicating design rationale. A case study is presented to illustrate two key features of the approach: (1) seamless integration of separate modular domain ontologies and instance knowledge related to ...


Improved Knowledge Management Through First-Order Logic In Engineering Design Ontologies, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden May 2010

Improved Knowledge Management Through First-Order Logic In Engineering Design Ontologies, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

Center for e-Design Publications

This paper presents the use of first-order logic to improve upon currently employed engineering design knowledge management techniques. Specifically, this work uses description logic in unison with Horn logic, to not only guide the knowledge acquisition process but also to offer much needed support in decision making during the engineering design process in a distributed environment. The knowledge management methods introduced are highlighted by the ability to identify modeling knowledge inconsistencies through the recognition of model characteristic limitations, such as those imposed by model idealizations. The adopted implementation languages include the Semantic Web Rule Language, which enables Horn-like rules to ...


Semantic Relatedness Measures For Identifying Relationships In Product Development Processes, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden Aug 2009

Semantic Relatedness Measures For Identifying Relationships In Product Development Processes, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

Center for e-Design Proceedings

The Semantic Web, especially in relation to ontologies, provides a structured, formal framework for knowledge interoperability. This trait has been exploited by both the biomedical community in development of the Human Gene Ontology [1] and also by geographers in development of geospatial ontologies [2]. Using semantic relatedness techniques, researchers from both communities have been able to develop and integrate comprehensive knowledge bases. Beyond knowledge integration, semantic relatedness techniques have also been able to provide each community with a unique insight into relationships between concepts in their respective domains. In the engineering community, semantic relatedness techniques promise to provide similar insight ...


A Decision Support Ontology For Collaborative Decision Making In Engineering Design, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden Jan 2009

A Decision Support Ontology For Collaborative Decision Making In Engineering Design, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden

Center for e-Design Proceedings

Complex products and increasing domain specialization have led to a collaborative design environment in which multiple partners are relied upon to successfully realize a product. In such an environment there is a need for computational frameworks that assist in communicating decision making knowledge. In this research a Decision Support Ontology (DSO) is developed to facilitate decision making within collaborative design. The structure of the information model developed reflects a priori knowledge of decision making and supports the communication of information independent of any specific decision method. Accordingly, the DSO includes decision-related information such as the design issue, alternatives, evaluation, criteria ...


Analyzing And Implementing A Feature Mapping Approach To Cad System Interoperability, John Altidor, Jack C. Wileden, Yiwen Yang, Leen Hanayneh, Yan Wang Jan 2009

Analyzing And Implementing A Feature Mapping Approach To Cad System Interoperability, John Altidor, Jack C. Wileden, Yiwen Yang, Leen Hanayneh, Yan Wang

Center for e-Design Proceedings

Interoperable information exchange between computer-aided design (CAD) systems is one of the major problems to enable information integration in a collaborative engineering environment. Although a significant amount of work has been done on the extension and standardization of CAD data formats as well as the cooperation of CAD systems in both academy and industry, these approaches are generally low-level and narrowly targeted. Lack of fundamental study of interoperability and generic solution to this problem is the major issue. Our intention of this research is to design a solution of CAD feature interoperability as generic as possible based on a theoretical ...

A Web-Based Environment For Documentation And Sharing Of Engineering Design Knowledge, Justin A. Rockwell, Paul Witherell, Rui Fernandes, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden

Center for e-Design Proceedings

This paper presents the foundation for a collaborative Web-based environment for improving communication by formally defining a platform for documentation and sharing of engineering design knowledge throughout the entire design process. In this work an ontological structure is utilized to concisely define a set of individual engineering concepts. This set of modular ontologies link together to create a flexible, yet consistent, product development knowledge-base. The resulting infrastructure uniquely enables the information stored within the knowledge-base to be readily inspectable and computable, thus allowing for design tools that reason on the information to assist designers and automate design processes. A case ...
