๐Ÿšจ Apply for a 3-year postdoctoral fellowship to work on computational models of planning, meta-control, and how they can be used to explain patterns of anxiety. Opportunities to use cutting edge OPM-MEG to study their neural implementation. Competitive funding generously

Clinical trials reveal that some antidepressants are over 100% more effective than placebo, while others barely outperform it. The largest meta-analysis (Cipriani et al., 2018) compared 21 antidepressants in 116,477 patients, revealing striking differences in efficacy and

Coded a toy Pong agent using Active Inference ๐Ÿค–. Paddle doesnโ€™t track the ballโ€”it infers position/velocity via online free energy minimisation (Variational Laplace) & chooses actions by rolling out expected surprise. Green = belief ๐Ÿง  | Ball = true state โšพ๐Ÿ“ #AI #NeuroAI

Testing an Active Inference agent in a 3D drone navigation task โ€” it infers its own position and velocity from noisy observations, and selects actions by rolling out belief-based trajectories and minimizing expected free energy. #ActiveInference #BayesianLearning #AI #AGI
