February 2018 Gwern.net newsletter with 3 new essays and links on genetics/AI/psychology/economics, 1 book review, 1 movie review, and 7 pieces of music.
This is the February 2018 edition of the Gwern.net newsletter; previous, January 2018 (archives). This is a collation of links and summary of major changes, overlapping with my Changelog; brought to you by my donors on Patreon.

Genetics:
-
Everything Is Heritable:
-
“Genome-wide study identifies 611 loci associated with risk tolerance and risky behaviors”, et al 2018
-
“DeepGS: Predicting phenotypes from genotypes using Deep Learning”, et al 2017 (rrBLUP is one of the best generic methods if you’re working with relatively small n/p GWAS data, and this is not a setup or design that favors CNNs: single trait w/no auxiliary data, tiny n/p, shallow CNN, no hyperparameter or architecture optimization or data augmentation—but the crippled CNN still beats rr-BLUP. What would happen if one did a full-strength CNN GWAS across the UKBB? The memory and computation requirements would be exorbitant, but one can dream.)
-
“2017 was the year consumer DNA testing blew up” (“More people took genetic ancestry tests last year than in all previous years, combined. The number of people who have had their DNA analyzed with direct-to-consumer genetic genealogy tests more than doubled during 2017 and now exceeds 12 million, according to industry estimates.”)
-
“Whose poop is that on the lawn? DNA testing is cracking down on doggie-doo offenders” (unexpected consequences of exponential decreases in DNA testing costs)
-
-
Recent Evolution:
-
“Common schizophrenia alleles are enriched in mutation-intolerant genes and in regions under strong background selection”, et al 2018 ( ‘Background selection’ as the mechanism driving all the human mutation load in common schizophrenia variants? Could this also explain other traits like intelligence?)
-
-
Engineering:
-
“Metaphase II oocytes from human unilaminar follicles grown in a multi-step culture system”, et al 2018 ( media; steps towards massive embryo selection & IES)
-
AI:
-
“DAML: One-Shot Imitation from Observing Humans via Domain-Adaptive Meta-Learning”, et al 2018 ( video)
-
“Unicorn: Continual Learning with a Universal, Off-policy Agent”, et al 2018; “IMPALA: Scalable Distributed Deep-RL with Importance Weighted Actor-Learner Architectures”, et al 2018 ( blog; Real transfer learning, and even more wallclock speedups/parallel scaling, on ALE)
-
“Learning and Querying Fast Generative Models for Reinforcement Learning”, et al 2018 (Learning deep environment models for planning)
-
“Deep Reinforcement Learning Doesn’t Work Yet”, Alex Irpan
-
“Machine Theory of Mind”, et al 2018
-
“ENAS: Efficient Neural Architecture Search via Parameter Sharing”, et al 2018
-
“One Big Net for Everything”, 2018 (An update on NNAISENSE? Or still just proposals like 2015?)
Statistics/Meta-Science:
-
“Statistical power of clinical trials has increased whilst effect size remained stable: an empirical analysis of 137,032 clinical trials between 1975–2017”, et al 2017 (Medical experiments are still usually grossly underpowered but things seem to be getting a little bit better.)
Politics/religion:
-
“The Impact of Media Censorship: Evidence from a Randomized Field Experiment in China”, 2018
-
“What Really Happened At The School Where Every Graduate Got Into College” (The Stainless Steel Law of Evaluation: “The better designed the impact assessment of a social program, the more likely is the resulting estimate of net impact to be zero.”)
Psychology/biology:
-
“Deep image reconstruction from human brain activity”, et al 2018a; “End-to-end deep image reconstruction from human brain activity”, et al 2018b
-
“Adversarial Examples that Fool both Human and Computer Vision”, et al 2018 (it’s a start)
-
“It’s a Dog’s World, Especially in the Lab. Where Are the Cats?” (particularly in my catnip research, I’ve noticed a lamentable lack of cat research.)
Technology:
-
“Augur: a Decentralized Oracle and Prediction Market Platform”, et al 2018 (If you last read the original Augur/Truthcoin whitepapers back in ~2014, the mechanism design has changed radically so may be worth reading the latest whitepaper.)
-
The Alinea Project (I’m awed by the depth of this guy’s foray into doing “modernist cuisine” at home and replicating every single Alinea recipe published in Alinea, with impeccable photographic documentation.)
Economics:
-
“Effects Of Copyrights On Science—Evidence From The US Book Republication Program”, 2018 (Estimating the large deadweight losses of copyright using the natural experiment of US expropriation of German copyrights in WWII)
-
“The Robots Are Coming for Garment Workers” (Automation comes to the last few steps in the clothes-making process. Reminds me of Hanson’s model of how automation/tech/capital initially serves as a complement to labor, making labor ever better off, but then at a sufficient point of development, flips over to being a substitute for labor.)
-
“Are We Running Out of Trademarks? An Empirical Study of Trademark Depletion and Congestion”, 2018
