Bayesian Nonparametric Hidden Semi-Markov Models

open access: yes, 2012
There is much interest in the Hierarchical Dirichlet Process Hidden Markov Model (HDP-HMM) as a natural Bayesian nonparametric extension of the ubiquitous Hidden Markov Model for learning from sequential and time-series data.

Electric Bus Charging Schedules Relying on Real Data-Driven Targets Based on Hierarchical Deep Reinforcement Learning

open access: yesIEEE Access
The charging scheduling problem of Electric Buses (EBs) is investigated based on Deep Reinforcement Learning (DRL). A Markov Decision Process (MDP) is conceived, where the time horizon includes multiple charging and operating periods in a day, while each

Long-Term Energy Consumption Minimization Based on UAV Joint Content Fetching and Trajectory Design

open access: yesSensors
Caching the contents of unmanned aerial vehicles (UAVs) could significantly improve the content fetching performance of request users (RUs). In this paper, we study UAV trajectory design, content fetching, power allocation, and content placement problems

High Fidelity Real-Time Optimization of Multi-Robot Lines Processing Shared and Non-Deterministic Material Flows

open access: yesRobotics
Multi-robot ensembles comprising several manipulators are commonly used in industrial settings to process non-deterministic flows of items loaded by an upstream source onto a shared transportation system.

Cost Rate Heuristics for Semi-Markov Decision Processes

open access: yes, 1991
In response to the computational complexity of the dynamic programming/backwards induction approach to the development of optimal policies for semi-Markov decision processes, we propose a class of heuristics which result from an inductive process which proceeds forwards in time.

SEMI-MARKOV DECISION PROCESSES WITH INCOMPLETE STATE OBSERVATION : DISCOUNTED COST CRITERION

open access: yesJournal of the Operations Research Society of Japan, 1982
In this paper we study the infinite planning horizon, countable state, semiĀ·Markov decision processes (SMDP's) with the incomplete state observation under the average cost criterion. We show that this model can be transĀ­ formed to ordinary SMDP's, i.e., SMDP's with the complete state observation.

Uncertainty assessment of aquifer hydraulic parameters from pumping test data

open access: yesApplied Water Science
Data from pumping tests is a noisy process, and therefore, performing the pumping test numerous times will not get the same drawdown values. As a consequence, various pumping experiments lead to different values for aquifer parameter estimates.

Optimizing warfarin dosing for patients with atrial fibrillation using machine learning

open access: yesScientific Reports
While novel oral anticoagulants are increasingly used to reduce risk of stroke in patients with atrial fibrillation, vitamin K antagonists such as warfarin continue to be used extensively for stroke prevention across the world.
