It takes a Flywheel to fly: Kickstarting and keeping the A/B testing momentum
https://www.microsoft.com/en-us/research/group/experimentation-platform-exp/articles/it-takes-a-flywheel-to-fly-kickstarting-and-keeping-the-a-b-testing-momentum/ In this article, we present the A/B Testing Flywheel – a tool for implementing and growing a successful A/B testing program. Our flywheel focuses on navigating the value-investment cycle which supports and motivates the continued funding required to scale up an A/B testing program. We developed the A/B Testing...

A/B testing at LinkedIn: Assigning variants at scale
https://engineering.linkedin.com/blog/2020/a-b-testing-variant-assignment The validity of A/B testing is rooted in the assumption that each variant is assigned to a random member. That’s why it’s critical to find a good randomization algorithm. There are three main characteristics of a good variant assignment function: Assignment of variants to members happens according to the...
PsychRNN: An accessible and flexible python package for training recurrent neural network models on cognitive tasks
https://www.eneuro.org/content/8/1/ENEURO.0427-20.2020 Task-trained artificial recurrent neural networks (RNNs) provide a computational modeling framework of increasing interest and application in computational, systems, and cognitive neuroscience. RNNs can be trained, using deep-learning methods, to perform cognitive tasks used in animal and human experiments and can be studied to investigate potential neural representations and...
DSP performance comparison Numpy vs. Cython vs Numba vs Pythran vs Julia
https://jochenschroeder.com/blog/articles/DSP_with_Python2/ In my previous post I talked about how we can significantly speed up python code using cython. However, to get the ultimate performance, we need to add significant amounts of boilerplate and the resulting code looks hardly like python any longer. I therefore tested two other popular packages for...
Momentary subjective well-being depends on learning and not reward
https://elifesciences.org/articles/57977 Many people believe they would be happier if only they had more money. And events such as winning the lottery or receiving a large pay rise do make people happy, at least temporarily. But recent studies suggest that the main factor driving happiness on such occasions is not the...
Measuring cognitive variables: simple answers for thorny questions
https://socialsciences.nature.com/posts/measuring-cognitive-variables-simple-answers-for-thorny-questions To quantify learning, we measure their physiological arousal when they hear the sound – say, whether their hands become sweaty. We don’t want to mistakenly take random fluctuations of sweat gland activity for evidence of learning, and so we only look at a specific time window after sound onset....
Longitudinally adaptive assessment and instruction increase numerical skills of preschool children
https://www.pnas.org/content/117/45/27945 Social inequality in mathematical skill is apparent at kindergarten entry and persists during elementary school. We therefore designed a procedure that enables teachers to assess the skills of each child and tailor instruction to child-specific levels of skill. The procedure is iterative: Assess, teach, reassess, and teach, with three...

UK ambulance services are testing a rescue jet suit
https://www.engadget.com/uk-ambulance-services-are-testing-jet-suit-paramedic-recoveries-124052727.html https://gravity.co/ The “Iron Man” jet suit we first saw back in 2017 might be less crazy than we first thought. Inventor Richard Browning and his company Gravity Industries have demonstrated that it may be a viable option to quickly get medical help to victims in remote areas. Working with...
