 and computational cost. As of right now, though this might change as we make progress in our experiments, we use:
 
 - Input Networks (Sensors & Feature Extractors): These networks map the raw state inputs to internal hidden states.
-  They are configured as standard dense networks with 2 hidden layers of 64 nodes each (`[64, 64]`) and utilize `tanh`
