Methods for Large Scale Total Least Squares Problems
Authors: Åke Björck, P. Heggernes, P. Matstoms
Venue: SIAM Journal on Matrix Analysis and Applications (2000)

The solution of the total least squares (TLS) problems, $\min_{E,f}\|(E,f)\|_F$ subject to (A+E)x=b+f, can in the generic case be obtained from the right singular vector corresponding to the smallest singular value $\sigma_{n+1}$ of (A, b). When A is large and sparse (or structured) a method based on Rayleigh quotient iteration (RQI) has been suggested by Björck. In this method the problem is reduced to the solution of a sequence of symmetric, positive definite linear systems of the form $(A^TA-\bar\sigma^2I)z=g$, where $\bar\sigma$ is an approximation to $\sigma_{n+1}$. These linear systems are then solved by a {\em preconditioned} conjugate gradient method (PCGTLS). For TLS problems where A is large and sparse a (possibly incomplete) Cholesky factor of ATA can usually be computed, and this provides a very efficient preconditioner. The resulting method can be used to solve a much wider range of problems than it is possible to solve by using Lanczos-type algorithms directly for the singular value problem. In this paper the RQI-PCGTLS method is further developed, and the choice of initial approximation and termination criteria are discussed. Numerical results confirm that the given algorithm achieves rapid convergence and good accuracy.}

Query performance analyser -: a web-based tool for IR research and instruction
Authors: Eero Sormunen, Sakari Hokkanen, Petteri Kangaslampi, Petri Pyy, Bemmu Sepponen
Venue: Proceedings of the 25th annual international ACM SIGIR conference on Research and development in information retrieval (2002)

The Interactive Query Performance Analyser (QPA) for information retrieval systems is a Web-based tool for analysing and comparing the performance of individual queries. On top of a standard test collection, it gives an instant visualisation of the performance achieved in a given search topic by any user-generated query. In addition to experimental IR research, QPA can be used in user training to demonstrate the characteristics of and compare differences between IR systems and searching strategies. The first prototype (versions 3.0 and 3.5) of the Query Performance Analyser was developed at the Department of Information Studies, University of Tampere, to serve as a tool for rapid query performance analysis, comparison and visualisation [4,5]. Later, it has been applied to interactive optimisation of queries [2,3]. The analyser has served also in learning environments for IR [1].The demonstration is based on the newest version of the Query Performance Analyser (v. 5.1). It is interfaced to a traditional Boolean IR system (TRIP) and a probabilistic IR system (Inquery) providing access to the TREC collection and two Finnish test collections. Version 5.1 supports multigraded relevance scales, new types of performance visualisations, and query conversions based on mono- and multi-lingual dictionaries. The motivation in developing the analyser is to emphasise the necessity of analysing the behaviour of individual queries. Information retrieval experiments usually measure the average effectiveness of IR methods developed. The analysis of individual queries is neglected although test results may contain individual test topics where general findings do not hold. For the real user of an IR system, the study of variation in results is even more important than averages.
Participatory design in a human-computer interaction course: teaching ethnography methods to computer scientists
Authors: Jerry B. Weinberg, Mary L. Stephen
Venue: Proceedings of the 33rd SIGCSE technical symposium on Computer science education (2002)

Empirical evidence shows the ability for computer technology to deliver on its promises of enhancing our quality of life relies on how well the application fits our understanding of how things work. Software designers need to apply methods that provide insights into the user's mental model of the application's target task and to invite the user to be an active participant in the design process. This paper reports on our efforts to design an HCI curriculum around ethnographic techniques of data gathering and paper prototyping. Initial results are presented that study the course's effects on student's attitudes regarding approaches to software design and their long term design behavior.
Robust epsilon visibility
Authors: Florent Duguet, George Drettakis
Venue: Proceedings of the 29th annual conference on Computer graphics and interactive techniques (2002)

Analytic visibility algorithms, for example methods which compute a subdivided mesh to represent shadows, are notoriously unrobust and hard to use in practice. We present a new method based on a generalized definition of extremal stabbing lines, which are the extremities of shadow boundaries. We treat scenes containing multiple edges or vertices in degenerate configurations, (e.g., collinear or coplanar). We introduce a robust &epsilon; method to determine whether each generalized extremal stabbing line is blocked, or is touched by these scene elements, and thus added to the line's generators. We develop robust blocker predicates for polygons which are smaller than &epsilon;. For larger &epsilon; values, small shadow features merge and eventually disappear. We can thus robustly connect generalized extremal stabbing lines in degenerate scenes to form shadow boundaries. We show that our approach is consistent, and that shadow boundary connectivity is preserved when features merge. We have implemented our algorithm, and show that we can robustly compute analytic shadow boundaries to the precision of our chosen &epsilon; threshold for non-trivial models, containing numerous degeneracies.
Agent oriented programming with Ada'95: application to financial markets
Authors: Férial Benachour Hait
Venue: ACM SIGAda Ada Letters (2000)

This paper shows the suitability of Object Oriented Programming language Ada'95 for Agent Oriented Programming. Agent oriented programming relies on the assumption, that a complex distributed software system can be programmed as a set of communicating, interacting, knowledge base entities called (software) agents. In this work we study the financial market case by introducing new modeling and implementation tools in order to simulate and understand some properties of the market evolution process. Object -Oriented modeling of social systems requires the integration of new concepts related to mental processes such as learning, planning, knowledge representation and communication. If one defines an agent as an object combination of mental state to perceive its environment and achieve some goals, a knowledge base to hold its memory and an interfacing communication with other entities then all the above properties could be fulfilled. In this paper we describe a method for the use of Ada object Oriented Programming language for the implementation of a MAS plate-form. The results obtained in the experimental part lead to some parameters of the model validation, like the agent's performance in increasing their own wealth and their adapted behavior throughout the evolving market.

The Integral Tree Representation of the Symmetric Group
Authors: Sarah Whitehouse
Venue: Journal of Algebraic Combinatorics: An International Journal (2001)

Let i>Tn be the space of fully-grown i>n-trees and let i>Vn and i>Vn&prime; be the representations of the symmetric groups &Sigma;i>n and &Sigma;i>n+1 respectively on the unique non-vanishing reduced integral homology group of this space. Starting from combinatorial descriptions of i>Vn and i>Vn&prime;, we establish a short exact sequence of {\bb Z}\Sigma_{n+1}-modules, giving a description of i>Vn&prime; in terms of i>Vn and i>Vi>n+1. This short exact sequence may also be deduced from work of Sundaram.Modulo a twist by the sign representation, i>Vn is shown to be dual to the Lie representation of &Sigma;i>n, Liei>n. Therefore we have an explicit combinatorial description of the integral representation of &Sigma;i>n+1 on Liei>n and this representation fits into a short exact sequence involving Liei>n and Liei>n+1.
Computing the SVD of a General Matrix Product/Quotient
Authors: Gene Golub, Knut Solna, Paul Van Dooren
Venue: SIAM Journal on Matrix Analysis and Applications (2000)

In this paper we derive a new algorithm for constructing a unitary decomposition of a sequence of matrices in product or quotient form. The unitary decomposition requires only unitary left and right transformations on the individual matrices and amounts to computing the generalized singular value decomposition of the sequence. The proposed algorithm is related to the classical Golub--Kahan procedure for computing the singular value decomposition (SVD) of a single matrix in that it constructs a bidiagonal form of the sequence as an intermediate result. When applied to two matrices this new method is an alternative way of computing the quotient and product SVD and is more economical than current methods.
Managing graph(ical) complexity with raisin and its category explorer
Authors: Douglas N. Gordin
Venue: Proceedings of the 2nd international symposium on Smart graphics (2002)

Graphs offer a powerful way to view the relationships between objects. Yet, as useful as small graphs are for seeing relationships, large graphs are frustrating because their complexity overwhelms our ability to trace through patterns of relationships. The Raisin system helps manage this complexity by giving the means to layout a graph well; index a graph using categories based on structure and other criteria; highlight and abstract via selection, hiding, and aggregation; and create new categories that distill the user's conclusions for analysis and presentation.

Error Bounds for Linear Matrix Inequalities
Authors: Jos F. Sturm
Venue: SIAM Journal on Optimization (1999)

For iterative sequences that converge to the solution set of a linear matrix inequality, we show that the distance of the iterates to the solution set is at most \( O(\epsilon ^{2^{-d}}) \). The nonnegative integer d is the so-called degree of singularity of the linear matrix inequality, and $\epsilon $ denotes the amount of constraint violation in the iterate. For infeasible linear matrix inequalities, we show that the minimal norm of $\epsilon $-approximate primal solutions is at least \( 1/O(\epsilon ^{1/(2^{d}-1)}) \), and the minimal norm of $\epsilon $-approximate Farkas-type dual solutions is at most \( O(1/ \epsilon ^{2^{d}-1}) \). As an application of these error bounds, we show that for any bounded sequence of $\epsilon $-approximate solutions to a semidefinite programming problem, the distance to the optimal solution set is at most \( O(\epsilon ^{2^{-k}}) \), where k is the degree of singularity of the optimal solution set.
Dealers of Lightning: Xerox PARC and the Dawn of the Computer Age
Authors: Michael A. Hiltzik, Rutkoff
Venue:  (1999)

:Dealers of Lightning is the riveting story of the legendary Xerox PARC  a collection of eccentric young inventors brought together by Xerox Corporation at a facility in Palo Alto, California, during the mind-blowing intellectual ferment of the seventies and eighties. Here for the first time Michael Hiltzik, a correspondent for the Los Angeles Times, reveals in piercing detail the true story of the extraordinary group that aimed to bring about a technological dawn that would change the world  and succeeded. Based on extensive interviews with the scientists, engineers, administrators, and corporate executives who lived the story, Dealers of Lightning takes the read on a journey from PARC's beginnings in a dusty, abandoned building at the edge of the Stanford University campus to its triumph as a hothouse of ideas that spawned not only the first personal computer, but the windows-style graphical user interface, the laser printer, much of the indispensable technology of the Internet, and a great deal more. It shows how and why Xerox, despite its willingness to grant PARC unlimited funding and the responsibility for developing breakthroughs to keep the corporation on the cutting edge of office technology, remained forever unable to grasp (and, consequently, exploit) the innovations that PARC delivered  and it details the increasing frustration of the original PARC scientists, many of whom would go on to build their fortunes upon the very ideas Xerox so rashly discarded. More than just a riveting historical narrative, Dealers of Lightning brings to life an unforgettable cast of characters. Among them: Bob Taylor  the preacher's son from rural Texas who would be considered a prophet by some and a cantankerous egomaniac by others, whose fearless (and feared) leadership of a team of computer renegades made them the heroes of the embryonic Silicon Valley; Jack Goldman  the Xerox chief scientist who convinced the stolid corporation to stake tens of millions of dollars on PARC while warning that the investment might not pay off for years  if it paid off at all; Alan Kay  PARC's creative and philosophical soul, who suffered years of ridicule for envisioning a computer that could be tucked under the arm yet would contain the power to store books, symphonies, letters, poems, and drawings  until he arrived at Palo Alto and met the people who would build it; and Steve Jobs  who, aided by Xerox's indifference to PARC's most momentous inventions, staged a daring raid to obtain the technology that would end up at the heart of the Macintosh: the machine that for a time helped Apple dominate an explosive new market. Dealers of Lightning is an unprecedented look at the ideas, the inventions, and the individuals that propelled Xerox PARC to the frontier of technohistory  and the corporate machinations that almost prevented it from achieving greatness.
Visual Basic Telephony
Authors: Chris Brookins, Holly & Brookins
Venue:  (1995)

:Until recently, integrating the power of the desktop PC with the accessibility of the telephone to build applications such as voice mail, fax-on-demand, and touch-tone data retrieval has been reserved for a select few. Telephony development tools were proprietary, complex, and expensive. But in 1991, a revolution occurred in software development: Microsoft unveiled Visual Basic which turned the development tools industry upside down with its remarkable features: easy-to-use graphical environment; Industry standard BASIC language; completely open architecture for third-party add-on components; unparalleled data access; no runtime fees. Now, this revolution is sweeping through the telephony industry. As developers begin to realize they can build telephony applications the open-architecture way - by using Visual Basic, standard telephony interfaces, and other off-the-shelf components interest in Windows computer telephony has taken off. From two of the creators of Visual Voice, the first telephony toolkit for Visual Basic, comes this book on the integration of Visual Basic, Windows, and telephony. Read it and you'll understand why: Over a million people already use Visual Basic; telephony is a key technology in Windows development - you can easily build custom Windows telephony applications.Author Biography: Chris Brookins is vice president of development at Stylus Innovation, Inc. Since 1993, he has led the development of the Visual Voice product family. Krisztina Holly is vice president and co-founder of Stylus Innovation, Inc. She is a frequent lecturer at MIT.
