DESCRIPTION:Please join us for our fortnightly journal club online via zoo
 m where two presenters will jointly present a topic together. The next top
 ic is 'Inference and knowledge transfer of latent task structure' presente

 ct\, we need first to identify the underlying causal structure of our envi
 ronment. However\, this underlying structure is not directly observable. A
 n agent must first infer which hidden state it is in from noisy sensory in
 formation\, and secondly\, represent this state in a way which enables inf
 erence of the relevant action policy\, and re-use this knowledge when in a
  new situation with the same underlying causal structure. Here\, we presen
 t two papers that study how humans infer and represent latent states. The 
 first paper shows how hidden structure is inferred using information from 
 a temporal sequence\, and may then be used in inductive reasoning (Pudhiyi
 dath et al.\, 2021). The second paper shows how structural knowledge may b
 e represented as abstract basis sets\, which can then be re-deployed when 
 a new situation requiring a similar basis set arises (Mark et al.\, 2020).
