# s-phys: photonic ('natural') intelligence: a laser chaos can make decisions

<< [..] over the past several years, researchers have demonstrated that physical objects [..] can also "make decisions" by responding to feedback from their environments >>

AA << has demonstrated that the ultrafast, chaotic oscillatory dynamics in lasers makes these devices capable of decision making and reinforcement learning, which is one of the major components of machine learning >>

<< [..] this is the first demonstration of ultrafast photonic decision making or reinforcement learning, and it opens the doors to future research on "photonic intelligence" >>

AA << utilize the computational power inherent in physical phenomena [..] The computational power of physical phenomena is based on 'infinite degrees of freedom,' and its resulting 'nonlocality of interactions' and 'fluctuations'  >>

AA << call such systems 'natural Intelligence' in contrast to artificial intelligence" >>
