Advanced Probabilistic Modeling and Analysis Laboratory

In our Advanced Probabilistic Modeling and Analysis Laboratory, we focus on the innovative use of Joint Probability Trees (JPTs), a formalism that facilitates the learning and reasoning of joint probability distributions in a tractable manner for practical applications. JPTs are distinctive for their capability to incorporate both symbolic and subsymbolic variables within a unified hybrid model, without necessitating prior knowledge about variable dependencies or specific distribution families. Within the context of our Virtual Research Building, JPTs are employed to construct and analyze joint probability distributions derived from log data of robot experiments. This enables us to critically evaluate experimental outcomes and harness robot experience data for learning purposes, paving the way for advancements in robot performance and decision-making processes.
