Distributionally robust linear regression through the lens of adversarial training
Elis Stefansson, David Vävinggren, Antônio H. Ribeiro
Distributionally robust optimization (DRO) studies parameter estimation under uncertainty in the underlying probability distribution and has emerged as a principled framework for a…
Faster shortest-path algorithms using the acyclic-connected tree
Elis Stefansson, Oliver Biggar, Karl H. Johansson
We provide a method to obtain beyond-worst-case time complexity for any single-source-shortest-path (SSSP) algorithm by exploiting modular structures in graphs. The key novelty is…
Efficient Planning in Large-scale Systems Using Hierarchical Finite State Machines
Elis Stefansson, Karl H. Johansson
We consider optimal planning in a large-scale system formalised as a hierarchical finite state machine (HFSM). A planning algorithm is proposed computing an optimal plan between an…
Efficient and Reconfigurable Optimal Planning in Large-Scale Systems Using Hierarchical Finite State Machines
Elis Stefansson, Karl H. Johansson
In this paper, we consider a planning problem for a large-scale system modelled as a hierarchical finite state machine (HFSM) and develop a control algorithm for computing optimal…
Hierarchical Finite State Machines for Efficient Optimal Planning in Large-scale Systems
Elis Stefansson, Karl H. Johansson
In this paper, we consider a planning problem for a hierarchical finite state machine (HFSM) and develop an algorithm for efficiently computing optimal plans between any two states…
Computing Complexity-aware Plans Using Kolmogorov Complexity
Elis Stefansson, Karl H. Johansson
In this paper, we introduce complexity-aware planning for finite-horizon deterministic finite automata with rewards as outputs, based on Kolmogorov complexity. Kolmogorov complexit…
Hierarchical Game-Theoretic Planning for Autonomous Vehicles
Jaime F. Fisac, Eli Bronstein, Elis Stefansson +3
The actions of an autonomous vehicle on the road affect and are affected by those of other drivers, whether overtaking, negotiating a merge, or avoiding an accident. This mutual de…
