Query: A2: Extracting Cyclic Switchings from DOB-nets for Rejecting Excessive
  Disturbances   Reinforcement Learning (RL) is limited in practice by its gray-box nature,
which is responsible for insufficient trustiness from users, unsatisfied
interpretation for human intervention, inadequate analysis for future
improvement, etc. This paper seeks to partially characterize the interplay
between dynamical environments and the DOB-net. The DOB-net obtained from RL
solves a set of Partially Observable Markovian Decision Processes (POMDPs). The
transition function of each POMDP is largely determined by the environments,
which are excessive external disturbances in this research. This paper proposes
an Attention-based Abstraction (A${}^2$) approach to extract a finite-state
automaton, referred to as a Key Moore Machine Network (KMMN), to capture the
switching mechanisms exhibited by the DOB-net in dealing with multiple such
POMDPs. This approach first quantizes the controlled platform by learning
continuous-discrete interfaces. Then it extracts the KMMN by finding the key
hidden states and transitions that attract sufficient attention from the
DOB-net. Within the resultant KMMN, this study found three patterns of cyclic
switchings (between key hidden states), showing controls near their saturation
are synchronized with unknown disturbances. Interestingly, the found switching
mechanism has appeared previously in the design of hybrid control for
often-saturated systems. It is further interpreted via an analogy to the
discrete-event subsystem in the hybrid control.
