Connectionists: PhD position in computational neuroscience/machine learning

[Rui Ponte Costa]

The Neural and Machine Learning group<http://ruipcosta.weebly.com/> at the University of Bristol, UK is looking for a PhD student to work at the intersection between computational neuroscience and machine learning (funded by a EPSRC Doctoral Training grant). We are part of the Bristol Computational Neuroscience Unit<http://www.bristol.ac.uk/engineering/research/computational-neuroscience/> and are associated with the world-class neuroscience and machine learning communities at Bristol, and we also collaborate with other national and international labs. Applicants should hold or expect to obtain a First Class or Upper Second Class Honours degree or equivalent in engineering, computer science, physics, mathematics, computational neuroscience or machine learning (or equivalent), and a strong interest in neural and biological systems. This position is open to applicants who are UK citizens, or EU citizens resident in the UK for at least 3 years.

Project: Deep temporal credit assignment with dynamic synapses
Successful behaviour relies on the ability of animals and machines to predict the outcome of their actions. Selecting which synapses (or parameters) to adjust to trigger the right action is a hard problem as it depends on past sensory information. Exactly how does the brain solve such temporal credit assignment problems has remained largely enigmatic. In this project, the student will developed a novel theoretical framework to address the temporal credit assignment problem. This framework will be compared with experimental observations and tested in machine learning tasks in collaboration with experimental neuroscientists and machine learning researchers.
