📢 New #COLM2025 paper 📢

Standard benchmarks give every LLM the same questions. This is like testing 5th graders and college seniors with *one* exam! 🥴

Meet Fluid Benchmarking, a capability-adaptive eval method delivering lower variance, higher validity, and reduced cost.

I'm excited cause I'm teaching/coordinating a new unique class, where we teach new PhD students all the "soft" skills of research, incl. ideation, reviewing, presenting, interviewing, advising, etc.

Each lecture is taught by a different LTI prof! It takes a village! maartensap.com/11705/Fall20...
