New paper introducing a framework to better quantify uncertainty in LLM evaluations (led by @LLuettgau🙌). A beta Python package (developed by @HarryCoppock🚀) is available if you want to try it out.

➡️Get in touch if you have any Qs/feedback!

🦙Excited to share this demo of Alpaca
🔥Highlights: ~GPT3.5 performance for < 600$🔥

The goal was to have a simple model /training procedure that academics could study and improve with limited resources

We achieved that by finetuning a 7B LLaMA on 52K generated instructions

Presenting my PhD work on exploration 🔍 this afternoon at 3:15 (BST)
Tomorrow's Brain Meeting will be given by @DubMagda
from @MPC_CompPsych🧠

'Computational and cognitive mechanisms of exploration heuristics' will discuss how forms of exploration relate to neurobiological, developmental,
and mental health processes.
