Case study research: the ”Butterfly” robot
(Master thesis, 2019)For at roboter skal ha en sjanse til a komme nær mennesket når det gjelder manipulering av objekter, ma de benytte seg av mer enn bare å gripe for å manipulere objekter. Dette er der utvikling av ikke-gripende manipulering ... -
Causal connections between socioeconomic disparities and COVID-19 in the USA
(Peer reviewed; Journal article, 2022)With the increasing use of machine learning models in computational socioeconomics, the development of methods for explaining these models and understanding the causal connections is gradually gaining importance. In this ... -
Causal Episode Explanations for Reinforcement Learning Applications
(Master thesis, 2023)Denne master oppgaven presenterer en ny metode for omfattende forklaring av hvordan en forsterkningslærende agent handler i en episode. Metoden forklarer hvorfor agenten tar sine handlinger og hvordan disse handlingene ... -
Causal versus Marginal Shapley Values for Robotic Lever Manipulation Controlled using Deep Reinforcement Learning
(Peer reviewed; Journal article, 2022)We investigate the effect of including application knowledge about a robotic system states’ causal relations when generating explanations of deep neural network policies. To this end, we compare two methods from explainable ... -
Cautious MPC-based control with Machine Learning
(Master thesis, 2018)Using Gaussian processes as a nonparametric regression model together with model predictive control has the recent years showed promising results by utilizing the expected uncertainty that follows the GP. By utilizing the ... -
