If people knew how much of my PhD has consisted of reading about something new, referencing back to Elements of Statistical Learning, and simply writing down what I learned… It feels like a cheat code!

btw this is why friends dont let friends skip the “boring classical ML” chapters in Elements of Statistical Learning‼️ (True story: the origin of this case study is that @alanjeffares.bsky.social[big EoSL nerd] looked at the neural net eq&said “kinda looks like GBTs in EoSL Ch10”&we went from there)

Part 2: Why do boosted trees outperform deep learning on tabular data?? @alanjeffares.bsky.social & I suspected that answers to this are obfuscated by the 2 being considered very different algs🤔 Instead we show they are more similar than you’d think — making their diffs smaller but predictive!🧵1/n

From double descent to grokking, deep learning sometimes works in unpredictable ways.. or does it? For NeurIPS(my final PhD paper!), @alanjeffares.bsky.social & I explored if&how smart linearisation can help us better understand&predict numerous odd deep learning phenomena — and learned a lot..🧵1/n
