MULTI-MODAL UTILE DISTINCTIONS Multi-Modal Utile Distinctions
We introduce Multi-Modal Utility Trees (MMU), an algorithm for autonomously learning decision treebased state abstractions in Partially Observable Markov Decision Processes with multi-modal observations. MMU builds the trees using the Kolmogorov-Smirnov statistical test. Additionally, MMU incorporates the ability to perform online tree restructuring, enabling it to build and maintain a compact ...

متن کاملUtile or futile: biomarkers in the ICU
Biomarkers complement other clinical information by proving quantitative data regarding a pathophysiological mechanism that can be used for the early diagnosis of a specific disease, to monitor and guide treatment, and to predict the risk of death or other adverse events. The stronger the link between the information provided by the biomarker and the immediate clinical course of action that we ...
متن کاملUtile Distinctions for Relational Reinforcement Learning
We introduce an approach to autonomously creating state space abstractions for an online reinforcement learning agent using a relational representation. Our approach uses a tree-based function approximation derived from McCallum’s [1995] UTree algorithm. We have extended this approach to use a relational representation where relational observations are represented by attributed graphs [McGovern...
متن کاملOvercoming Incomplete Perception with Utile Distinction Memory
This paper presents a method by which a reinforcement learning agent can solve the incomplete perception problem using memory. The agent uses a hidden Markov model (HMM) to represent its internal state space and creates memory capacity by splitting states of the HMM. The key idea is a test to determine when and how a state should be split: the agent only splits a state when doing so will help t...
