Andrew Ng Launches A Campaign For Data-Centric AI
https://www.forbes.com/sites/gilpress/2021/06/16/andrew-ng-launches-a-campaign-for-data-centric-ai A Chat with Andrew on MLOps: From Model-centric to Data-centric AI (youtube) In the dominant model-centric approach to AI, according to Ng, you collect all the data you can collect and develop a model good enough to deal with the noise in the data. The established process calls for...
The impact of a lack of mathematical education on brain development and future attainment
https://www.pnas.org/content/118/24/e2013155118 Our knowledge of the effect of a specific lack of education on the brain and cognitive development is currently poor but is highly relevant given differences between countries in their educational curricula and the differences in opportunities to access education. We show that within the same society, adolescent students...
Editorial: Children's competencies development in the home learning environment
https://www.frontiersin.org/articles/10.3389/fpsyg.2021.706360/full https://www.frontiersin.org/research-topics/11100/childrens-competencies-development-in-the-home-learning-environment In the paper by Napoli et al. the authors examine characteristics of the child and family that relate to the frequency of parent-child literacy and numeracy engagement. Although some characteristics (i.e., parent education and children’s age) were related to both literacy and numeracy engagement, parents’ beliefs about the...
Using large-scale experiments and machine learning to discover theories of human decision-making
https://www.science.org/doi/10.1126/science.abe2629 https://github.com/jcpeterson/choices13k https://mayank-agrawal.com/papers/PetersonBourginAgrawalReichmanGriffiths21.pdf Predicting and understanding how people make decisions has been a long-standing goal in many fields, with quantitative models of human decision-making informing research in both the social sciences and engineering. We show how progress toward this goal can be accelerated by using large datasets to power machine-learning...
Childhood cross-ethnic exposure predicts political behavior seven decades later: Evidence from linked administrative data
https://www.science.org/doi/10.1126/sciadv.abe8432 Does contact across social groups influence sociopolitical behavior? This question is among the most studied in the social sciences with deep implications for the harmony of diverse societies. Yet, despite a voluminous body of scholarship, evidence around this question is limited to cross-sectional surveys that only measure short-term consequences...
My stack for research ML projects
https://xcorr.net/2021/06/09/my-stack-for-research-ml-projects/ The Full Stack Deep Learning class from Berkeley is a good place to learn how to organize deep learning projects. I had originally intended to go all-in on cloud infra to run models and analyze data. The class makes a solid argument that it ends being cheaper to build...
Reactivation-induced motor skill learning
https://www.pnas.org/content/118/23/e2102242118 Learning motor skills commonly requires repeated execution to achieve gains in performance. Motivated by memory reactivation frameworks predominantly originating from fear-conditioning studies in rodents, which have extended to humans, we asked the following: Could motor skill learning be achieved by brief memory reactivations? To address this question, we had...
Overconfidence in news judgments is associated with false news susceptibility
https://www.pnas.org/content/118/23/e2019527118 We examine the role of overconfidence in news judgment using two large nationally representative survey samples. First, we show that three in four Americans overestimate their relative ability to distinguish between legitimate and false news headlines; respondents place themselves 22 percentiles higher than warranted on average. This overconfidence is,...
Storytelling increases oxytocin and positive emotions and decreases cortisol and pain in hospitalized children
https://www.pnas.org/content/118/22/e2018409118 Storytelling is a distinctive human characteristic that may have played a fundamental role in humans’ ability to bond and navigate challenging social settings throughout our evolution. However, the potential impact of storytelling on regulating physiological and psychological functions has received little attention. We investigated whether listening to narratives from...
Built to last: An ex-product leader at LinkedIn, Twitter on the only stickiness metric that matters
https://mixpanel.com/blog/built-to-last-an-ex-product-leader-at-robinhood-linkedin-and-twitter-on-the-only-stickiness-metric-that-matters/ In this new era, it’s become even more important to design products that are easy for users to adopt, learn, and extract value from in the future. Below, I’m sharing the qualities that define the products that stick around—and the one metric that will help you predict whether yours...
