A Primer on Maximum Causal Entropy Inverse Reinforcement Learning [article]

Adam Gleave, Sam Toyer
2022 arXiv   pre-print
Inverse Reinforcement Learning (IRL) algorithms infer a reward function that explains demonstrations provided by an expert acting in the environment.  ...  Maximum Causal Entropy (MCE) IRL is currently the most popular formulation of IRL, with numerous extensions.  ...  Acknowledgements We would like to thank Alyssa Li Dayan, Michael Dennis, Yawen Duan, Daniel Filan, Erik Jenner, Niklas Lauffer and Cody Wild for feedback on earlier versions of this manuscript.  ...

How hidden are hidden processes? A primer on crypticity and entropy convergence

John R. Mahoney, Christopher J. Ellison, Ryan G. James, James P. Crutchfield
2011 Chaos  
This is done by recasting previous results on the convergence of block entropy and block-state entropy in a geometric setting, one that is more intuitive and that leads to a number of new results.  ...  For example, we connect crypticity to how an observer synchronizes to a process. We show that the block-causal-state entropy is a convex function of block length.  ...  Over time, a system "realizes" which paths are undesirable and quits them. Consider an individual learning to navigate a new city.  ...

Stochastic Thermodynamics of Learning

Sebastian Goldt, Udo Seifert
2017 Physical Review Letters  
Here, we use stochastic thermodynamics to analyse the learning of a classification rule by a neural network.  ...  We show that the information acquired by the network is bounded by the thermodynamic cost of learning and introduce a learning efficiency η<1.  ...  However, we can show that I G (w n : T n ) is a lower bound on I(w n : T n ) using the maximum entropy principle.  ...
