Mean-field Theory and Synchronization in Random Recurrent Neural Networks
Authors: Emmanuel Dauce, Olivier Moynot, Olivier Pinaud, Manuel Samuelides
Venue: Neural Processing Letters (2001)

In this paper, we first present a new mathematical approach, based on large deviation techniques, for the study of a large random recurrent neural network with discrete time dynamics. In particular, we state a mean field property and a law of large numbers, in the most general case of random models with sparse connections and several populations. Our results are supported by rigorous proofs. Then, we focus our interest on large size dynamics, in the case of a model with excitatory and inhibitory populations. The study of the mean field system and of the divergence of individual trajectories allows to define different dynamical regimes in the macroscopic parameters space, which include chaos and collective synchronization phenomenons. At last, we look at the behavior of a particular finite-size system submitted to gaussian static inputs. The system adapts its dynamics to the input signal, and spontaneously produces dynamical transitions from asynchronous to synchronous behaviors, which correspond to the crossing of a bifurcation line in the macroscopic parameters space.
Low-Degree Spanning Trees of Small Weight
Authors: Samir Khuller, Balaji Raghavachari, Neal Young
Venue: SIAM Journal on Computing (1996)

Given $n$ points in the plane, the degree-$K$ spanning-tree problem asks for a spanning tree of minimum weight in which the degree of each vertex is at most $K$. This paper addresses the problem of computing low-weight degree-$K$ spanning trees for $K>2$. It is shown that for an arbitrary collection of $n$ points in the plane, there exists a spanning tree of degree 3 whose weight is at most 1.5 times the weight of a minimum spanning tree. It is shown that there exists a spanning tree of degree 4 whose weight is at most 1.25 times the weight of a minimum spanning tree. These results solve open problems posed by Papadimitriou and Vazirani. Moreover, if a minimum spanning tree is given as part of the input, the trees can be computed in $O(n)$ time. The results are generalized to points in higher dimensions. It is shown that for any $d \ge 3$, an arbitrary collection of points in $\Re^d$ contains a spanning tree of degree 3 whose weight is at most 5/3 times the weight of a minimum spanning tree. This is the first paper that achieves factors better than 2 for these problems.
A semiotic-based framework to user interface design
Authors: Jair C Leite
Venue: Proceedings of the second Nordic conference on Human-computer interaction (2002)

This work proposes a framework based on the Semiotic Engineering approach that drives designers to specify the application conceptual model and its associated user interface. Our work contributes to user interface design by proposing the LEMD, a linguistic formalism to the user interface specification in an abstract and structured way focusing on what he/she really wants to mean to the users. The resulting specification could be mapped on conventional widgets.
Optimality of Energy Estimates for the Wave Equation with Nonlinear Boundary Velocity Feedbacks
Authors: Judith Vancostenoble, Patrick Martinez
Venue: SIAM Journal on Control and Optimization (2000)

We consider the wave equation damped by a nonlinear boundary velocity feedback q(ut). First we consider the case where q has a linear growth at infinity. We prove that the usual decay rate estimates proved by Nakao [Differential Integral Equations, 8 (1995), pp. 681--688], Haraux and Zuazua [Arch. Rational Mech. Anal., 100 (1988), pp. 191--206], Conrad, Leblond, and Marmorat [in Proceedings of the Fifth International Federation of Automatic Control Symposium on Control of Distributed Parameter Systems, Perpignan, 1989, pp. 101--116], Zuazua [SIAM J. Control Optim., 28 (1990), pp. 466--477], and Komornik [in Control and Estimation of Distributed Parameter Systems: Nonlinear Phenomena, Internat. Ser. Numer. Math. 118, Birkhäuser, Basel, 1994, pp. 253--266] when q has a polynomial behavior at zero and by the second author [ESAIM Control Optim. Calc. Var., 4 (1999), pp. 419--444] in the general case are in fact optimal in one space dimension. More generally, we prove that the energy decays exactly like the solution of an explicit and simple ordinary differential equation.Next we study the problem when q is bounded at infinity. We prove that strong solutions decay exponentially to zero, and we exhibit a sequence of weak solutions for which the associated energy decays to zero at infinity as slowly as the iterated logarithms go to infinity at infinity.

On the maximum number of touching pairs in a finite packing of translates of a convex body
Authors: Károly Bezdek
Venue: Journal of Combinatorial Theory Series A (2002)

A Minkowski space Md = (Rd, || ||) is just Rd with distances measured using a norm || ||. A norm || || is completely determined by its unit ball {x ∈ Rd | ||x|| ≤ 1} which is a centrally symmetric convex body of the d-dimensional Euclidean space Ed. In this note we give upper bounds for the maximum number of times the minimum distance can occur among n points in Md, d ≥ 3. In fact, we deal with a somewhat more general problem namely, we give upper bounds for the maximum number of touching pairs in a packing of n translates of a given convex body in Ed, d ≥ 3.
Core J2EE Patterns: Best Practices and Design Strategies
Authors: Deepak Alur, Dan Malks, John Crupi
Venue:  (2001)

From the Book:In the world of software, a pattern is a tangible manifestation of an organization's tribal memory. A pattern provides a common solution to a common problem and so, within the culture of one specific organization or within one domain, naming and then specifying a pattern represents the codification of a common solution, drawn from proven, prior experience. Having a good language of patterns at your disposal is like having an extended team of experts sitting at your side during development: by applying one of their patterns, you in effect take the benefit of their hard-won knowledge. As such, the best patterns are not so much invented as they are discovered and then harvested from existing, successful systems. Thus, at its most mature state, a pattern is full of things that work, absent of things that don't work, and revealing of the wisdom and rationale of its designers. Deep, really useful, patterns are typically ancient: you see one and will often remark, "Hey, I've done that before." However, the very naming of the pattern gives you a vocabulary that you didn't have previously and so helps you apply that pattern in ways you otherwise might have not have realized. Ultimately, the effect of such a pattern will be to make your system simpler. Patterns not only help you build simpler systems that work, but they also help you build beautiful programs. In a culture of time starvation, writing beautiful software is often impossible. That's sad, for as professionals, we strive to build things of quality. By applying a good set of patterns, it is possible to bring a degree of elegance in to your systems that might otherwise have been lacking. The authors of Core J2EE Patterns have harvested a really useful set of patterns. Don't get me wrong: J2EE is certainly an important platform, enabling teams to build some very powerful systems. However, reality is, there is still a wide semantic gap between the abstractions and services that J2EE provides and the final application that a team must build. Patterns such as specified in this book represent solutions that appear again and again in filling that gap. By applying these patterns, you thus carry out the primary means of reducing software risk: you write less software. Rather than discovering these solutions on your own, apply these patterns, which have already proven their utility in existing systems. More than just naming a set of patterns, the authors make them approachable by specifying their semantics using the UML. Additionally, they show you how to apply these patterns and how to refactor your system to take advantage of them. Again, it's just like having a team of experts sitting at your side.

Solvability of multi-point boundary value problem at resonance (III)
Authors: Bing Liu, Jianshe Yu
Venue: Applied Mathematics and Computation (2002)

In this paper, we consider the following second-order ordinary differential equation x" = f(t,x(t),x'(t)) + e(t), t ∈ (0, 1), (E) subject to one of the following boundary value conditions: x(0) = ∑ αix(ξi), x(1) = βx(η), (B1) x(0) = ∑ αix(ξi), x'(1) = βx'(η), (B2) x'(0) = ∑ αix'(ξi), x(1) = βx(η), (B3) x'(0) = ∑ αix'(ξi), x'(1) = βx'(η), (B4) where αi (1≤i≤m-2), β ∈ R, 0 < ξ1 < ξ2 < ... < ξm-2 < 1, 0 < η < 1. When all the αi's have no the same sign, some existence results are given for (E) with boundary conditions (B1), (B2), (B3), (B4) at resonance case. We also give some examples to demonstrate our results.

Piecewise Polynomial Collocation Methods for Linear Volterra Integro-Differential Equations with Weakly Singular Kernels
Authors: Hermann Brunner, Arvet Pedas, Gennadi Vainikko
Venue: SIAM Journal on Numerical Analysis (2001)

In the first part of this paper we study the regularity properties of solutions of linear Volterra integro-differential equations with weakly singular or other nonsmooth kernels. We then use these results in the analysis of two piecewise polynomial collocation methods for solving such equations numerically. The main purpose of the paper is the derivation of optimal global convergence estimates and the analysis of the attainable order of local superconvergence at the collocation points.

Analysis of simulation experiments by bootstrap resampling
Authors: Russell C. H. Cheng
Venue: Proceedings of the 33nd conference on Winter simulation (2001)

This tutorial considers some very general procedures for analysing the results of a simulation experiment using bootstrap resampling. Bootstrapping has come to be recognised in statistics as being far ranging and effective. However it is not so well known in simulation despite being ideally suited for use in such a context. We discuss aspects ranging from the elementary to the advanced. We describe the rationale and the simple steps needed to implement bootstrapping in (i) estimation of the distributional properties of the output and its dependence on factors of interest; (ii) model fitting; (iii) model selection; (iv) model validation; (v) sensitivity analysis.
Eyes alive
Authors: Sooha Park Lee, Jeremy B. Badler, Norman I. Badler
Venue: ACM Transactions on Graphics (TOG) (2002)

For an animated human face model to appear natural it should produce eye movements consistent with human ocular behavior. During face-to-face conversational interactions, eyes exhibit conversational turn-taking and agent thought processes through gaze direction, saccades, and scan patterns. We have implemented an eye movement model based on empirical models of saccades and statistical models of eye-tracking data. Face animations using stationary eyes, eyes with random saccades only, and eyes with statistically derived saccades are compared, to evaluate whether they appear natural and effective while communicating.
Implementation of RNS-Based Distributed Arithmetic Discrete Wavelet Transform Architectures Using Field-Programmable Logic
Authors: Javier Ramírez, Antonio García, Uwe Meyer-Bäse, Fred Taylor, Antonio Lloris
Venue: Journal of VLSI Signal Processing Systems (2002)

Currently there are design barriers inhibiting the implementation of high-precision digital signal processing (DSP) objects with field programmable logic (FPL) devices. This paper explores overcoming these barriers by fusing together the popular distributed arithmetic (DA) method with the residue number system (RNS) for use in FPL-centric designs. The new design paradigm is studied in the context of a high-performance filter bank and a discrete wavelet transform (DWT). The proposed design paradigm is facilitated by a new RNS accumulator structure based on a carry save adder (CSA). The reported methodology also introduces a polyphase filter structure that results in a reduced look-up table (LUT) budget. The 2C-DA and RNS-DA are compared, in the context of a FPL implementation strategy, using a discrete wavelet transform (DWT) filter bank as a common design theme. The results show that the RNS-DA, compared to a traditional 2C-DA design, enjoys a performance advantage that increases with precision (wordlength).
Text genre classification with genre-revealing and subject-revealing features
Authors: Yong-Bae Lee, Sung Hyon Myaeng
Venue: Proceedings of the 25th annual international ACM SIGIR conference on Research and development in information retrieval (2002)

Subject or prepositional content has been the focus of most classification research. Genre or style, on the other hand, is a different and important property of text, and automatic text genre classification is becoming important for classification and retrieval purposes as well as for some natural language processing research. In this paper, we present a method for automatic genre classification that is based on statistically selected features obtained from both subject-classified and genre classified training data. The experimental results show that the proposed method outperforms a direct application of a statistical learner often used for subject classification. We also observe that the deviation formula and discrimination formula using document frequency ratios also work as expected. We conjecture that this dual feature set approach can be generalized to improve the performance of subject classification as well.

Performance characterization of a hardware mechanism for dynamic optimization
Authors: Brian Fahs, Satarupa Bose, Matthew Crum, Brian Slechta, Francesco Spadini, Tony Tung, Sanjay J. Patel, Steven S. Lumetta
Venue: Proceedings of the 34th annual ACM/IEEE international symposium on Microarchitecture (2001)

We evaluate the rePLay microarchitecture as a means for reducing application execution time by facilitating dynamic optimization. The framework contains a programmable optimization engine coupled with a hardware-based recovery mechanism. The optimization engine enables the dynamic optimizer to run concurrently with program execution. The recovery mechanism enables the optimizer to make speculative optimizations without requiring recovery code.We demonstrate that a rePLay configuration performing a small suite of simple optimizations on Alpha code attains an average of 13% reduction in execution cycles on the SPEC2000 integer benchmarks over a rePLay configuration not performing optimizations, and a 21% reduction over an aggressive standard superscalar microarchitecture.
