At the same time, most great coaches tend to outperform win probability model expectations So being simply average in spots with >75% win probability may point to something

videoI just pushed a new paper to arXiv. I realized that a lot of my previous work on robust losses and nerf-y things was dancing around something simpler: a slight tweak to the classic Box-Cox power transform that makes it much more useful and stable. It's this f(x, λ) here:

Something happened in year 774 that was so powerful we can measure the radioactivity in old tree rings. Best guess is a solar flare, 10 times more powerful than the Carrington Event in 1859 that zapped telegraph wires. Worth considering the effect of the next one. Details:

My textbook now includes an updated figure from Carter & McCullough, 2014. It's now generated from the raw data. It's a striking image. The uncorrected effect size is d = 0.62 based on 198 studies. Now, large replications later, we know the true effect size is 0. What a waste.

Adam, a 9-yr old optimizer, is the go-to for training LLMs (eg, GPT-3, OPT, LLAMA). Introducing Sophia, a new optimizer that is 2x faster than Adam on LLMs. Just a few more lines of code could cut your costs from $2M to $1M (if scaling laws hold). https://t.co/GrMY600lLO 🧵⬇️

Another example: Take two glasses of equally sweet water and mix them together. Children of intermediate age think that the resulting solution will be sweeter than the originals! Similar results have been found for water temperature.
