A widely held view is that the Gini coefficient is not decomposable by subgroups. This paper proposes an axiomatic framework that ensures well-behaved within and between-group terms under which the Gini is decomposable with a novel and unique formula. https://t.co/xy74eUfwQp

Instead of testing for bias from potential misspecification of model restrictions, it's nearly optimal to adapt, averaging restricted and unrestricted estimates using data-driven weights. shinyApp: https://t.co/i8cYk2fP5p Paper: https://t.co/Wdc5U8Mh3s

this 17 year old homeschooled girl refuted a conjecture that was unsolved for 40 years, and which professional mathematicians worked on for years without solving she was rejected from most graduate programs she applied to, because she did not have a degree

In a paper published in the journal Transport Policy, researchers at the University of Tennessee - Knoxville analyzed the impacts of new fare technology and fare policies on system-level ridership https://t.co/cJ71nS8qXT

New research suggests that transit agencies see ridership gains when they adopt monthly fare-capping policies, which are primarily intended to make fares more equitable.

I teach the Kalman filter as a special implementation of a class of Gaussian Processes (GPs). Much of the modern world runs on these algorithms so a shame they are not more central to training, if that's the case.
The Kalman Filter was once a core topic in EECS curricula. Given it's relevance to ML, RL, Ctrl/Robotics, I'm surprised that most researchers don't know much about it, and many papers just rediscover it. KF seems messy & complicated, but the intuition behind it is invaluable 1/4

I really enjoyed working on this with @AlisdairMcKay, great to see it get published -- also some follow-up work coming soon!
This paper presents a method for using empirical evidence on the effects of policy shocks to construct counterfactuals following changes in policy rules, without violating the Lucas critique @ChristianKWolf @AlisdairMcKay

The benefits of new technologies accrue not only to high-skilled labor but also to owners of capital in the form of higher capital incomes. @ben_moll @LukaszRachel & Pascual Restrepo show how this has increased income and wealth inequality since the 1980s https://t.co/jl96524UjH

Excited to announce our new paper and software for multiview analysis: supervised learning with multiple sets of features. Can be used with lasso/elastic net; the idea generalizes to boosting and random forests. See https://t.co/vuXf7v1Ddp for a 3 min video explaining the idea.

In China, weak property rights over land generate considerable misallocation of land and capital across farmers within villages. The loss in agricultural efficiency is amplified through the selection of lower productivity farmers into agriculture https://t.co/jl9651Njs9

When Spanish triathlete Diego Méntriga noticed that British triathlete J. Teagle went the wrong way before the finish line, Mentriga waited for him so he could take his deserved 3rd place. “He was in front of me the whole time. He deserved it.” —Méntriga

Where are Knoxville movers coming from or going to? New York City, Chicago, and Los Angeles are the top 3 origin cities for people relocating to Knoxville. Washington DC, Atlanta, and Bend are the top 3 destination cities for people moving away from Knoxville.
