We employ a contextual combinatorial multi-armed bandit framework to learn the unknown parameters of an energy consumption model which is necessary for energy-efficient navigation. Four different agents: Thompson Sampling, Disjoint LinUCB, Hybrid LinUCB, and greedy algorithms are implemented to observe their performance. All experiments are conducted on the output of a Luxembourg SUMO traffic simulation. The main finding of this research is that contextual information such as speed and acceleration data contributes to better learning of parameters. Although the contextual combinatorial algorithms seem promising for addressing the energy-efficient shortest path problem, none of the agents achieve zero regret consistently which indicates that further improvements are necessary to obtain the desired results. sv dc.identifier.coursecode DATX05 sv dc.identifier.uri https://hdl.handle.net/20.500.12380/301396 dc.language.iso eng sv dc.setspec.uppsok Technology dc.subject Contextual combinatorial multi-armed bandit sv dc.subject online learning sv dc.subject electric vehicles sv dc.subject energy consumption prediction sv dc.subject computer science sv dc.title Online Learning for Energy Efficient Navigation using Contextual Information sv dc.type.degree Examensarbete för masterexamen sv dc.type.uppsok H
