Wainwright and Emma Brunskill Summary and Contributions: The paper presents a method for estimation of the underlying POMDP of an RL problem for subsequent solution it with a parametrised policy. The MLP takes the concatenation of the observation and half of the latent variables ( x_ {1:d},d=\lfloor D/2 \rfloor ) as the input, and output the scale and translation factors \alpha and t as introduced in Sect.
