Recent evolution:
Soft sweeps are the dominant mode of adaptation in the human genome
, Schrider & Kern 2017 (Detection of 2000 instances of recent human selection, half of which are specific to individual human populations, and many of which affect the central nervous system. Note this doesn’t cover polygenic selection, so it’s a very loose lower bound on how much recent human evolution there has been.)Comparative Genomic Evidence For Self-Domestication In Homo sapiens

AI:
Recurrent Environment Simulators
, Chiappa et al 2017 (towards deep model-based planning; related discussion)
If I’m understanding this right, it can be seen as related to Hinton’sUsing Human Brain Activity to Guide Machine Learning
, Fong et al 2017dark knowledge
and knowledge distillation in NNs: you use a teacher NN to provide additional supervision on the image classification problem by indicating hard & easy examples and also what is theright
probability to assign to all the wrong classifications in order to refine the loss function. In this case, the SVM is guided by the human brain fMRI activations which indicate which instances are hard/easy and so which ones it should concentrate on (an error on a hard instance should lead to smaller adjustments than an error on an easy one). This sort of supervision could be quite interesting if you think about its use for AI risk problems - moral dilemmas, for example.In-Datacenter Performance Analysis of A Tensor Processing Unit [TPU]

Books
Nonfiction:
- Moon Dust: In Search of the Men Who Fell to Earth, Smith 2005 (review)
Fiction:
- The Adventures of Dr. McNinja (the long-running series comes to an end; having read it since ~2008, it’s surprising to reread the whole series and realize that in between all the humorous action drama like banditos riding raptors or surfing a robotic Dracula back from the Moon, was lurking a fairly complex & well-thought-out time-travel SF story with very long callbacks and a bittersweet ending, with writing that improves as much as the art does over its 2006-2017 run. In some respects, it’s a little dated - looking back, I recognize it as something of an artifact of the ’00s Western Internet culture in being part of a ninja fad along with Real Ultimate Power, Ninja Burger, Megatokyo etc - but I’m still impressed at how Hastings makes it all come together, suggesting either he planned it out much further back than I ever expected or is a master of retcons. It is not the greatest time-travel story ever, or greatest martial arts story, but I will always enjoy reading action with a brain.)
Film/TV
Animated:
Live-action:
- DNA Dreams (short 2013 documentary on Beijing Genomics Institute and the research on IQ; the results still haven’t come out, having been pre-empted by Rietveld et al 2013 finding the first IQ hits, subsequent GWASes’ demonstration that the BGI bet on rare variants was wrong, and reportedly internal BGI disarray due to a disastrous bet on in-house development of DNA sequencers to try to break free of the Illumina sequencer quasi-monopoly; the documentary is fatally compromised by the lack of any actual discussion of genetics, instead settling for occasional ominous music, wandering BGI’s admittedly impressive facilities, and occasional idiosyncratic scenes of dating or family life)
