Peter Dayan FRS is a British neuroscientist and computer scientist who is director at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, along with Ivan De Araujo. He is co-author of Theoretical Neuroscience,[2] an influential textbook on computational neuroscience. He is known for applying Bayesian methods from machine learning and artificial intelligence to understand neural function and is particularly recognized for relating neurotransmitter levels to prediction errors and Bayesian uncertainties.[3] He has pioneered the field of reinforcement learning (RL) where he helped develop the Q-learning algorithm, and made contributions to unsupervised learning, including the wake-sleep algorithm for neural networks and the Helmholtz machine.[4][5][6]
Education
[edit]Dayan studied mathematics at the University of Cambridge and then continued for a PhD in artificial intelligence at the University of Edinburgh School of Informatics on statistical learning[7] supervised by David Willshaw and David Wallace, focusing on associative memory and reinforcement learning.[7]
Career and research
[edit]After his PhD, Dayan held postdoctoral research positions with Terry Sejnowski at the Salk Institute and Geoffrey Hinton at the University of Toronto. He then took up an assistant professor position at the Massachusetts Institute of Technology (MIT), and moved to the Gatsby Charitable Foundation computational neuroscience unit at University College London (UCL) in 1998, becoming professor and director in 2002.[8] In September 2018, the Max Planck Society announced his appointment as a director at the Max Planck Institute for Biological Cybernetics in Tübingen.[9]
Awards and honours
[edit]Dayan was elected a Fellow of the Royal Society (FRS) in 2018.[10] He was awarded the Rumelhart Prize in 2012 and The Brain Prize in 2017.[10]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
