VP-STO: Via-point-based Stochastic Trajectory Optimization for Reactive Robot Behavior
Sylvain Calinon, Julius Maximilian Jankowski
Achieving reactive robot behavior in complex dynamic environments is still challenging as it relies on being able to solve trajectory optimization problems quickly enough, such that we can replan the future motion at frequencies which are sufficiently high ...
IEEE2023The statistical complexity of early-stopped mirror descent
Tomas Vaskevicius, Varun Kanade
Recently there has been a surge of interest in understanding implicit regularization properties of iterative gradient-based optimization algorithms. In this paper, we study the statistical guarantees on the excess risk achieved by early-stopped unconstrain ...
Oxford2023A greedy and distributable approach to the Lexicographic Bottleneck Assignment Problem with conditions on exactness
Solving the Lexicographic Bottleneck Assignment Problem (LexBAP) typically relies on centralised computation with order complexity. We consider the Sequential Bottleneck Assignment Problem (SeqBAP), which yields a greedy solution to the LexBAP and discuss ...
Elsevier2022Characterization and prediction of clinical pathways of vulnerability to psychosis through graph signal processing
Dimitri Nestor Alice Van De Ville, Maude Schneider, Daniela Maria Zöller, Anjali Bagunu Tarun
Causal interactions between specific psychiatric symptoms could contribute to the heterogenous clinical trajectories observed in early psychopathology. Current diagnostic approaches merge clinical manifestations that co-occur across subjects and could sign ...
eLIFE SCIENCES PUBL LTD2021The effects of model complexity and size on metabolic flux distribution and control: case study in Escherichia coli
Vassily Hatzimanikatis, Georgios Fengos, Tuure Eelis Hameri
Background Significant efforts have been made in building large-scale kinetic models of cellular metabolism in the past two decades. However, most kinetic models published to date, remain focused around central carbon pathways or are built around ad hoc re ...
BMC2021Injecting Knowledge in Data-driven Vehicle Trajectory Predictors
Alexandre Massoud Alahi, Ismail Nejjar, Mohammadhossein Bahari
Vehicle trajectory prediction tasks have been commonly tackled from two distinct perspectives: either with knowledge-driven methods or more recently with data-driven ones. On the one hand, we can explicitly implement domain-knowledge or physical priors suc ...
2021A Complexity Analysis Approach for Model-based System Engineering
Dimitrios Kyritsis, Jinzhi Lu, Xiaochen Zheng, Jinwei Chen
With the increasing complexity of the highly engineered products, Model-based Systems Engineering (MBSE) is proposed to support the complexity management of the product development. As the basic of complexity management, complexity analysis is used to meas ...
