A Distance Model for Rhythms

Modeling long-term dependencies in time series has proved very difficult to achieve with traditional machine learning methods. This problem occurs when considering music data. In this paper, we introduce a model for rhythms based on the distributions of di ...

New Directions in Cryptanalysis of Self-Synchronizing Stream Ciphers

Willi Meier, Shahram Khazaei

In cryptology we commonly face the problem of finding an unknown key K from the output of an easily computable keyed function F(C, K) where the attacker has the power to choose the public variable C. In this work we focus on self-synchronizing stream ciphe ...

A New DOA Estimation Method Using a Circular Microphone Array

Amin Karbasi

This paper proposes a new DOA (direction of arrival) estimation method based on circular microphone array. For an arbitrary number of microphones, it is analytically shown that DOA estimation reduces to an efficient non-linear optimization problem. Simulat ...

Algorithms for longer OLED lifetime

Friedrich Eisenbrand

We consider an optimization problem arising in the design of controllers for OLED displays. Our objective is to minimize the amplitude of the electrical current flowing through the diodes which has a direct impact on the lifetime of such a display. The opt ...

Design and optimization of district energy systems

François Maréchal, Daniel Favrat, Céline Weber

District energy systems have the potential to decrease the CO2 emissions linked to energy services (heating, hot water, cooling and electricity), thanks to the implementation of large polygeneration energy conversion technologies, connected to a group of b ...

Dynamic Origin-Destination Matrices Estimation Method for urban Networks

André-Gilles Dumont, Edward Chung, Emmanuel Bert

The aim of this paper is to explore a new approach to obtain better traffic demand (Origin-Destination, OD matrices) in case of dense urban networks. To improve the global process of OD demand estimation, this paper is focussing on a new methodology to exe ...

A heuristic for nonlinear global optimization relevant to discrete choice models estimation

Michel Bierlaire, Michaël Clément Louis Ghislain Thémans, Nicolas Zufferey

In most applications related to transportation, it is of major importance to be able to identify the global optimum of the associated optimization problem. The work we present in this paper is motivated by the optimization problems arising in the maximum l ...

A Generative Model for Rhythms

Samy Bengio, Jean-François Paiement

Modeling music involves capturing long-term dependencies in time series, which has proved very difficult to achieve with traditional statistical methods. The same problem occurs when only considering rhythms. In this paper, we introduce a generative model ...

Caratheodory bounds for integer cones

Friedrich Eisenbrand, Gennady Shmonin

We provide analogues of Caratheodory's theorem for integer cones and apply our bounds to integer programming and to the cutting stock problem. In particular, we provide an NP certificate for the latter, whose existence has not been known so far. © 2005 Els ...
