July 2018 Gwern.net newsletter with links on genetics, RL, true crime, tech economics, and 4 book reviews
This is the July 2018 edition of the Gwern.net newsletter; previous, June 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. This month I’d like to particularly thank my 2 anonymous donors, who gave $20,000.

#bga2018
” (r = 0.30/0.39 respectively; this appears to have been a preview of Allegrini et al 2018.) - “The Nature of Nurture: Using a Virtual-Parent Design to Test Parenting Effects on Children’s Educational Attainment in Genotyped Families”, Bates et al 2018 (Kong et al 2018’s nature-of-nurture seems to be mostly operating through causing parental SES)

- “Modeling functional enrichment improves polygenic prediction accuracy in UK Biobank and 23andMe data sets”, Marquez-Luna et al 2018 (Informative priors for Bayesian GWAS leads to a new height PGS record, 42% of variance—+2% from Lello et al 2017’s lasso)
- “GWAS Round 2” (New public release of UK Biobank GWASes/PGSes: 2,419→4,203 trait PGSes, with sex-stratified versions.)

- “Genomic underpinnings of lifespan allow prediction and reveal basis in modern risks”, Timmers et al 2018
- “Critical Need for Family-Based, Quasi-Experimental Designs in Integrating Genetic and Social Science Research”, D’Onofrio et al 2013 (Correlation ≠ causation: many “maternal smoking effects” are simply genetic or family-level confounds.)
- “Genetics & the Geography of Health, Behavior, and Attainment”, Belsky et al 2018b
- Whole-genome sequencing hits a new low: $350
- “Genealogists Turn to Cousins’ DNA and Family Trees to Crack Five More Cold Cases”

-
Engineering:
- “Genomic Selection in Dairy Cattle: The USDA Experience”, Wiggans et al 2017 (What has marker-assisted selection done for us lately? It’s “doubled the rate of genetic progress for traits of economic importance, decreased generation interval, increased selection accuracy, reduced previous costs of progeny testing, and allowed identification of recessive lethals.” Figure 1/Table 4/Figure 5.)
AI:
-
Google Waymo’s Arizona self-driving car program after 1 year; “Inside the Life of the World’s First Self-Driving Teen” (>400 daily riders, >39k kilometers daily; no fatalities or major injuries)
-
Dactyl: “Learning Dexterous In-Hand Manipulation”, OpenAI 2018 (blog; videos: 1/2; PPO-LSTM+domain-randomization in MuJoCo/Unity for sim2real transfer in a robotic hand grasper—nothing really new here but it is yet another demonstration of what brute force + systems engineering can do with existing DRL.)
-
“Large-Scale Visual Speech Recognition”, Shillingford et al 2018 (New SOTA for lipreading)
-
“Adversarial Reprogramming of Neural Networks”, Elsayed et al 2018 (NNs as “weird machines”)

-
“How to Fix Reinforcement Learning” (meta-learning)
-
Danbooru2017 is now on Kaggle (a version of the SFW subset—n = 300k tagged anime images—is now available on Kaggle, which should be convenient for people in that ecosystem)
Statistics/Meta-Science:
- “p-Hacking and False Discovery in A / B Testing”, Berman et al 2018 (Informative priors: Internet A/B tests are >70% testing null effects.)
- “Validating Teacher Effects On Students’ Attitudes And Behaviors: Evidence From Random Assignment Of Teachers To Students”, Blazar 2017 (How often does correlation = causation? 1 of 4 education measures’ teacher correlation w/grades is near-identical with the causal effect, 2 moderately biased, and 1 severely misleading.)
- “Sex matters in experiments on party drug—in mice: Ketamine lifts rodents’ mood only if administered by male researchers” (A reminder of why you can’t take animal experiments too seriously.)

- “Augmenting Long-term Memory” With Spaced Repetition (Michael Nielsen)
- “Melatonin: Much More Than You Wanted To Know”, Scott Alexander

Books
Nonfiction:
- Intellectual Talent: Research and Development, ed Keating 1976; Mathematical Talent: Discovery, description, and development, ed Stanley 1974 (early SMPY anthologies, recording the early results of the talent search and the immediate success of accelerating gifted students into Johns Hopkins college, the overall health of the participants, and SMPY’s unsuccessful struggle to get rid of the male overrepresentation at their extreme of math scores)
- Hanging Out with the Dream King: Conversations with Neil Gaiman and His Collaborators, ed. McCabe 2005 (review)
Fiction:
- Three Parts Dead (Craft Sequence #1), Gladstone 2012 (urban fantasy, sold to me as being unusually legal and economic-themed; not bad, but those aspects turn out to be minimal, arguably less than, say, Spice & Wolf, and some parts are a little derivative—City of Doors, anyone? I was a little more intrigued by the overall worldbuilding, with a geopolitical order polarized between upstart immortal human mage-kings seizing power with magic-science, and retrenched old gods.)
