Statistical performances of various deterministic and stochastic models for rainfall series disaggregation

This paper compares the performance of seven disaggregation models, based on various approaches and/or concepts, for the generation of 10mn time step rainfall series from hourly rainfall series. The so-called constant disaggregation model and a linear mode ...

, ,

Experiments on edge turbulence in the TCV tokamak have been performed for the first time at the beginning of 2003. This paper presents an overview of some of the results obtained, concentrating in particular on two areas: universality of density fluctuatio ...

Gradient estimates of return distributions

Samy Bengio, Christos Dimitrakakis

We present a general method for maintaining estimates of the distribution of parameters in arbitrary models. This is then applied to the estimation of probability distributions over actions in value-based reinforcement learning. While this approach is simi ...

Atomic-scale modelling of kinetic processes occurring during silicon oxidation

Alfredo Pasquarello, Angelo Bongiorno

We model the fundamental kinetic processes occurring during silicon oxidation at the atomic scale. We first focus on the diffusion of the, neutral O-2 molecule through the oxide layer. By combining ab initio and classical simulations, we derive a statistic ...

Tidal network ontogeny: Channel initiation and early development

Andrea Rinaldo

[1] The long-term morphological evolution of tidal landforms in response to physical and ecological forcings is a subject of great theoretical and practical importance. Toward the goal of a comprehensive theoretical framework suitable for large-scale, long ...

Stability Properties of Adaptive Real-Time Feedback Scheduling: A Statistical Approach

Giancarlo Ferrari Trecate

This paper focuses on the statistical analysis of an adaptive real-time feedback scheduling technique based on imprecise computation. We consider two-version tasks made of a mandatory and an optional part to be scheduled according to a feedback control rat ...

Design and Practical Use of Probabilistic Observers for Mass-Balance-Based Bioprocess Models

Benoît Chachuat, Olivier Bernard

In this paper, the design of probabilistic observers for mass-balance based bio- process models is investigated. It is assumed that the probability density function of every uncertain parameter, input and/or initial state is known a priori. Then, the proba ...

Spectral Entropy Based Feature for Robust ASR

Hervé Bourlard, Hynek Hermansky, Hemant Misra, Shajith Ikbal

In general, entropy gives us a measure of the number of bits required to represent some information. When applied to probability mass function (PMF), entropy can also be used to measure the ``peakiness'' of a distribution. In this paper, we propose using t ...

Audio-Video Person Clustering in Video Databases

Jean-Marc Odobez

A methodology towards person clustering in meeting databases is presented in this report. Such goal is generic to a number of problem in computer vision and more specifically in content-based video indexing and retrieval. First, the audio-stream was consid ...

On the drainage density of tidal networks

Andrea Rinaldo

The drainage density of a network is conventionally defined as (proportional to) the ratio of its total channelized length divided by the watershed area, and in practice, it is defined by the statistical distribution and correlation structure of the length ...
