The Pair Test: A computerised measure of learning and memory
https://link.springer.com/article/10.3758/s13428-020-01470-9 We developed a tablet-based paired-associate learning paradigm, the Pair Test, based on neurocognitive models of learning and memory. The aims are to (i) establish the utility of this novel memory tool for use with children across a wide age range, and (ii) examine test validity, reliability and reproducibility of...
Inferring latent learning factors in large-scale cognitive training data
https://www.nature.com/articles/s41562-020-00935-3 https://www.youtube.com/watch?v=BzX8I4Z39Qg The flexibility to learn diverse tasks is a hallmark of human cognition. To improve our understanding of individual differences and dynamics of learning across tasks, we analyse the latent structure of learning trajectories from 36,297 individuals as they learned 51 different tasks on the Lumosity online cognitive training...
Response to a specific and digitally supported training at home for students with mathematical difficulties
https://www.frontiersin.org/articles/10.3389/fpsyg.2020.02039/full The present study evaluated the effectiveness of a shortened, specialized, and digitally supported training program for enhancing numerical skills in primary and secondary school children with mathematical difficulty (MD). The participants (n = 57) were randomly assigned to two groups: for the experimental group, the tasks were differentiated and...
Software engineering as a research practice
https://ericmjl.github.io/blog/2020/8/21/software-engineering-as-a-research-practice/ https://www.youtube.com/watch?v=nxXr0LNdQUU At this year’s SciPy 2020, a talk and proceedings paper caught my eye: “Software Engineering as Research Method”. (Here are links to the paper and the talk.) In it, the authors, Mridul Seth and Sebastian Benthall, detailed the benefits that software skills bring to the academic and industrial...
Examining the factor structure of the home mathematics environment to delineate its role in predicting preschool numeracy, mathematical language, and spatial skills
https://www.frontiersin.org/articles/10.3389/fpsyg.2020.01925/full A growing body of evidence suggests that the ways in which parents and preschool children interact in terms of home-based mathematics activities (i.e., the home mathematics environment; HME) is related to children’s mathematics development (e.g., primarily numeracy skills and spatial skills); however, this body of evidence is mixed with...
5 data science questions a hiring manager must ask
https://medium.datadriveninvestor.com/5-data-science-questions-a-hiring-manger-must-ask-49b8bb512228 Over time, I have come to rely on these five questions for assessing if a data scientist could be a good fit. **I start with a real-world case study and ask about how the candidate will solve various problems related to that case study. **AI or Deep Learning is...
268 billion events with snowplow analytics and snowflake at CarGurus
https://www.bostata.com/268-billion-events-with-snowplow-snowflake-at-cargurus Two years ago we set up Open-Source Snowplow at CarGurus to fulfill a need for self-managed client-side instrumentation. Since that time it has become incredibly impactful for the entire company and has scaled significantly beyond what was originally envisioned. The following is an overview of why we set up...
What do you consider GOOD and GREAT retention?
https://www.lennysnewsletter.com/p/what-is-good-retention-issue-29 “Great retention is THE scalable way to grow a product. It’s the best indicator of product-market fit, it is the most important factor in a user’s lifetime value, and high retention drives all of the best acquisition strategies. It’s growth’s equivalent of the triple-word-score.” — Casey Winters As a...

Replacement cost: how much are we willing to pay in order to get this person to stay? If your...
Augmented creativity: Leveraging artificial intelligence for idea generation in the creative sphere
https://aisel.aisnet.org/ecis2020_rip/77/ The continuing attention that artificial intelligence has received in recent years has given rise to a debate about its possible role for creativity. Positions differ widely. Some argue that algorithms will replace human creativity altogether, while others claim that creativity is genuinely human and thus cannot be replaced. With...
