Spent the whole day reading unlearning papers. If any of the methods worked, I might hope to recover from the experience.

Unlike OpenAI, ostensibly controlled by a powerful holding entity, here have effectively 0 board power. This saga's shaping up like the Asimov's Spacer novels, but instead of each book exploring a different ratio of humans to robotic servants, it's a different level of corporate oversight.

We even found that sometimes with deep nets imputing 0 is better than running a fancy imputation algorithm because it’s more obvious which values are imputed so there’s less destruction of information.

Yeah, it makes sense, it gives you all the info you have. A powerful enough model can learn any reasonable imputation strategy implicitly.

In some clinical tasks the indicators are so useful, they’re almost as informative as the features themselves.

Thus the “controversiality”. Point is, hard to imagine any non-political reason to get any other compact EV than a tesla. Seems like nobody is even close, which i found surprising given the growing market.

Controversial opinion. It’s impossible to lease an EV in the US that’s even half as good a deal as @Tesla model 3/Y.

CTO’s the most slippery title in the world. Depending on the company, you’re either

1. A technical founder who never wanted to manage, now an IC engineer
2. A VP of Engineering
3. Leading all of EPD (+AI)
4. An influencer with no internal responsibilities

Phase 1 of my research career: "ML" = rebranding of the successful subset of AI.

Phase 2: "AI" = rebranding of the successful subset of ML.

Phase 3: AI & ML truly starting to diverge.

Can't find any person or AI that can explain Luka → Lakers. Only satisfying theory I can conjure: behind-the-scenes feud → "calf strain" masking a relationship strain → trade demand. But according to ChatGPT's research, Luka was blindsided by the trade.
