Automatically Generating Abstractions for Planning

An effective hierarchical decomposition of a problem would solve a task at lower level without violating the conditions in more abstract/higher levels of the hierarchy.

Learning Symbolic Representations for planning

In the pursuit of learning planner from data, I ended up reading Konidaris et al. (JAIR 2018). Getting through this paper was an onerous task. Which I would not like to do again. So, here are my notes on the key concepts from that paper, which are relevant for learning high-level, abstract planner.
