Turns out, you can learn a lot from a cheeseburger. 🍔📊
🎙️On @TheOfficialMRLA's "What’s with the Pineapple?" podcast, DoorDash Economist Erica Blom explains how the Cheeseburger Index works — and what it reveals about Detroit.
“The cheeseburger index looks at the average cost of a classic diner meal… The national average is $18.58; Detroit is $12.90.”
And that’s not all:
📈 94% restaurant resilience
📈 21% new restaurant growth
Detroit stands out in our State of Local Commerce report. ⤵️

🥚🥛Good morning, lower prices.
From DoorDash's first-ever State of Local Commerce Report, our Breakfast Basics Index — tracking the cost of breakfast grocery goods — is down 14% since March.
That’s one sign of strength in local economies: consumers are stretching their dollars further, and Main Street is proving resilient.

Neat visualization of Sweden life expectancy data by @planarrowspace revealing how there was no central tendency throughout history. Data in 1700 – 1900 is skewed by child mortality, where about half of kids died during their childhood, bringing the average to 35 years.

If it involves cryptocurrency, it's a scam.

Neural networks often pack many unrelated concepts into a single neuron – a puzzling phenomenon known as 'polysemanticity' which makes interpretability much more challenging. In our latest work, we build toy models where the origins of polysemanticity can be fully understood.

Really excited about our new work:
an intuitive extension of decision trees to tiny tree sums 🌳 ➡️ 🌳+🌳 yields surprisingly large improvements in prediction performance & disentanglement, all without sacrificing interpretability arxiv.org/abs/2201.11931

Do we all agree that whiteboard coding interviews simply test for (high IQ + high motivation + ability to work evenings/weekends) and not actual coding ability?
If so, why pretend? Just tell candidates to improve their chess Elo rating by X% and hire them on the spot.

Excited to share my new blog post about why generalization in RL is hard, and why our standard RL algorithms are fundamentally incompatible with generalizing well!

A more visual learner? Check out the talk instead: youtu.be/mOuf2fvNAhY
Why is generalization hard in RL? Can "just adding more data" fix it? Turns out that in general, the answer is no. In a new blog post, @its_dibya discusses this question: bair.berkeley.edu/blog/2021/…
Trying to generalize induces a POMDP, even if the problem is an MDP!

Great thread on the initial findings from Baby's First Years project. IRP director @profkmag, researcher @CostanzoMolly, and affiliates Greg Duncan @UCIrvine @KimberlyGNoble @TeachersCollege @Columbia Sarah Halpern-Meekin @UWSoHE & @Gen_Pov are among researchers on this study.
NEW FINDING: Cash support for low-income families changes their infants' brain activity. The first study from our #BabysFirstYears randomized control trial of poverty reduction is out, in @PNASnews. pnas.org/content/119/5/e2115…

Looks like HKU students and faculty are set to het a little sitting area where the #PillarofShame used to stand. I overheard saws and drills here the other day, here’s what’s in the works.

Replication crisis update
"none of the 193 experiments were described in sufficient detail"
"of the 50 experiments from 23 papers that were [repeated], effect sizes were, on average, 85 percent lower than those reported in the original experiments."

Facebook was one of the first companies to deploy face recognition at scale. Today @meta is announcing that it is turning it off. #ResponsibleAI is often deciding when to use, or in this case, not to use, AI. nytimes.com/2021/11/02/techn…

Many people have asked me how I make my interactive dashboards. I am surprised that many data scientists do not know HoloViz. So, I wrote an article about my favorite Python viz tools ❤️ HoloViz ❤️
