Learning Robust and Adaptive Representations: from Interactions, for Interactions
Interactions are ubiquitous in our world, spanning from social interactions between human individuals to physical interactions between robots and objects to mechanistic interactions among different components of an intelligent system. Despite their prevale ...
EPFL2023Current propagation type self-consistent leader-return stroke model
A current propagation type return stroke model which is consistent with the estimated distribution of the charge on the leader channel is described. The model takes into account the dispersion of the return stroke current along the return stroke channel. T ...
2023Tree root distribution modelling in different environmental conditions
David Andrew Barry, Paolo Perona, Massimiliano Schwarz
The ability to predict the spatial distribution of tree root system variables (e.g., the Root system Area (RA), the maximum root diameter, the number of roots in diameter classes, the density of fine roots, etc.) under different environmental conditions is ...
2022Comparing Annual Glare Simulation Methods
Recently, there have been multiple proposals for faster methods to calculate glare metrics, daylight glare probability (DGP) in particular. This is driven simultaneously by the lengthy times required to simulate DGP with a conventional image-based approach ...
2022Light Path Gradients for Forward and Inverse Rendering
Physically based rendering is a process for photorealistic digital image synthesis and one of the core problems in computer graphics. It involves simulating the light transport, i.e. the emission, propagation, and scattering of light through a virtual scen ...
EPFL2021A Current Propagation Type Return Stroke Model Consistent with the Leader Charge Distribution
Marcos Rubinstein, Farhad Rachidi-Haeri
We describe a current propagation type return stroke model which is consistent with the estimated distribution of the charge on the leader channel. The model takes into account the dispersion of the return stroke current along the return stroke channel. Th ...
2021« À l’Ouest, du nouveau ». Paysage commercial urbain à l’épreuve de la transition numérique
Dans le district de l’Ouest Lausannois s’annonce un vaste chantier, celui de la ville durable. La question commerciale semble étonnamment peu traitée, voire absente des documents de planification de ce morceau de ville en devenir. Pourtant, la transition n ...
2021From Data to Decisions: Distributionally Robust Optimization is Optimal
Daniel Kuhn, Peyman Mohajerin Esfahani
We study stochastic programs where the decision-maker cannot observe the distribution of the exogenous uncertainties but has access to a finite set of independent samples from this distribution. In this setting, the goal is to find a procedure that transfo ...
2020Slope-Space Integrals for Specular Next Event Estimation
Wenzel Alban Jakob, Tizian Lucien Zeltner, Guillaume Rémi Bruno Loubet
Monte Carlo light transport simulations often lack robustness in scenes containing specular or near-specular materials. Widely used uni- and bidirectional sampling strategies tend to find light paths involving such materials with insufficient probability, ...
ASSOC COMPUTING MACHINERY2020Fractional extreme distributions
We consider three classes of linear differential equations on distribution functions, with a fractional order alpha is an element of [0; 1]. The integer case alpha = 1 corresponds to the three classical extreme families. In general, we show that there is a ...
