Computing monotone policies for Markov decision processes: a nearly-isotonic penalty approach
Robert Mattila, Cristian R. Rojas, Vikram Krishnamurthy +1
This paper discusses algorithms for solving Markov decision processes (MDPs) that have monotone optimal policies. We propose a two-stage alternating convex optimization scheme that…
Trajectory Planning Under Vehicle Dimension Constraints Using Sequential Linear Programming
Mogens Graf Plessen, Pedro F. Lima, Jonas Martensson +2
This paper presents a spatial-based trajectory planning method for automated vehicles under actuator, obstacle avoidance, and vehicle dimension constraints. Starting from a nonline…
An analysis of the SPARSEVA estimate for the finite sample data case
Huong Ha, James S. Welsh, Cristian R. Rojas +1
In this paper, we develop an upper bound for the SPARSEVA (SPARSe Estimation based on a VAlidation criterion) estimation error in a general scheme, i.e., when the cost function is…
Asymptotically Efficient Identification of Known-Sensor Hidden Markov Models
Robert Mattila, Cristian R. Rojas, Vikram Krishnamurthy +1
We consider estimating the transition probability matrix of a finite-state finite-observation alphabet hidden Markov model with known observation probabilities. The main contributi…
