This summer I led a series of conversations in my lab about "AI" and our research. Some colleagues have shared "AI policies" for their labs and we discussed whether this would make sense for us. We decided it did not, and came up with a different approach. Please feel free to share & adapt!

Colleague didn't join a call but I had Gemini Notes switched on and it the transcript caught me talking to the cat.
Summary

Meeting logistics review addressed attendance verification and confirmed denial of additional catering requests.

Addressing Catering Request
Denial of secondary meal requests was finalized for shouting individuals. It was confirmed that participants had already consumed dinner.

Meeting Attendance Verification
Clarification regarding confirmed attendees occurred. Questions were raised about pending arrivals for the session.

Connection Status Check
Technical connection status was assessed. The presence of additional participants on the call remained under review.

A key challenge for computational psychiatry is to distinguish state from trait markers and go beyond cross-sectional studies. Here we show that as paranoia waxes and wanes in patients with schizophrenia, so too do volatility priors

Progress in Computational Psychiatry is is slowed down substantially because researchers (clinicians, cognitive neuroscientists, etc) lack the training in computational modelling and many studies dont follow the best practices in modelling. How can we change this? We've built the CPM toolbox:

I've long suspected this based on our own data - most variation in unselected samples is driven by low symptom scores, and it seems that most covariation is too. Seem important, especially re implications for the "p-factor". We need to confirm correlations from unselected samples in clinical ones
