Please join us for our fortnightly journal club online via zoom where two presenters will jointly present a topic together. The next topic is ‘Transformers in computational neuroscience – advances and future directions’ presented by Kris Jensen and Wayne Soo.

Zoom information: https://us02web.zoom.us/j/84958321096?pwd=dFpsYnpJYWVNeHlJbEFKbW1OTzFiQT09 Meeting ID: 849 5832 1096 Passcode: 506576

Summary: Since first rising to prominence 5 years ago, models based on the ‘transformer’ architecture have taken the field of machine learning by storm. This has included impressive advances on tasks ranging from image recognition and language modelling to predicting protein folding and automatically generating code. Meanwhile, transformers have continued to play a fairly minor role in systems and computational neuroscience, although some recent work has demonstrated potential uses of transformers both for neural data analysis and as explicit models of neural circuits. In this tutorial/discussion, we will first provide an introduction to the transformer architecture and go through a notebook implementing a minimal ‘vision transformer’. We will then talk briefly about some of the many impressive transformer-based advances in machine learning. Finally, we will highlight recent work that uses transformers in neuroscience and discuss the possible roles such attention-based architectures in the field moving forwards.
