Seeking entropy: complex behavior from intrinsic motivation to occupy action-state path space [article]

Jorge Ramírez-Ruiz, Dmytro Grytskyy, Rubén Moreno-Bote
2022 arXiv   pre-print
Intrinsically motivated agents can objectively determine what states constitute rewards, exploiting them to ultimately maximize action-state path entropy.  ...  Using discrete and continuous state tasks, we show that 'dancing', hide-and-seek and a basic form of altruistic behavior naturally result from entropy seeking without external rewards.  ...  Acknowledgments This work is supported by the Howard Hughes Medical Institute (HHMI, ref 55008742) and MINECO (Spain; BFU2017-85936-P) to R.M.-B, and MINECO/ESF (Spain; PRE2018-084757) to J.R.-R.  ...

The Free Energy Principle: Good Science and Questionable Philosophy in a Grand Unifying Theory

With powerful formalism that embeds a small set of assumptions, it purports to deal with complex adaptive dynamics ranging from barely unicellular organisms to complex cultural manifestations.  ...  The present paper assumes some of the abovementioned critiques, rejects the arguments advanced to invalidate the FEP's potential to be a GUT, and overcomes criticism thereof by reviewing FEP theorists'  ...  Such autonomous states can be equated with action and perception seeking to minimize surprisal or its upper bound, free energy.  ...
