Topology-Aware State Abstraction with Tangle Cores for Markov Decision Processes
Researchers have developed a new method for state abstraction in Markov Decision Processes called tangle-core abstraction. This approach uses graph tangles to create overlapping abstract states, which is particularly useful for problems with interface states like doors or hubs that connect multiple regions. The framework provides guarantees for value preservation and demonstrates favorable compression-return tradeoffs compared to existing methods in various navigation and grid-based environments. AI
