The Two Settings of Kind and Wicked Learning Environments
April 17, 2020There’s a paper on this topic that introduced the idea of “kind and wicked learning environments”:
https://pdfs.semanticscholar.org/5c5d/33b858eaf38f6a14b3f042202f1f44e04326.pdf
…in wicked environments it is difficult to do inference based on data. One solution seems to be to break down the problem in such a way that you can observe sub-problems in a kind environment.
The Two Settings of Kind and Wicked Learning Environments
Robin M. Hogarth1, Tomás Lejarraga2, and Emre Soyer3
Abstract
QT:{{” Inference involves two settings: In the first, information is acquired (learning); in the second, it is applied (predictions or choices). Kind learning environments involve close matches between the informational elements in the two settings and are a necessary condition for accurate inferences. Wicked learning environments involve mismatches. This conceptual framework facilitates identifying sources of inferential errors and can be used, among other things, to suggest how to target corrective procedures. For example, structuring learning environments to be kind improves probabilistic judgments. Potentially, it could also enable economic agents to exhibit maximizing behavior.

Quantifying SARS-CoV-2 transmission suggests epidemic control with digital contact tracing | Science

Great idea for #covid19… However, digital contact tracing has serious #privacy issues that have to be considered and perhaps ameliorated.

Fig 2 shows the breakdown of infections into four types:
pre-symptomatic, symptomatic, environmental, and asymptomatic, and they contribute 0.9, 0.8., 0.2, and 0.1 each to the basic reproduction number of 2. To stop the spread of infections, you need to take measures to get the area under the curve to below 1. The paper then shows that when you do quarantining and contact tracing, you can’t get the reproduction number below 1. However, if you improve the speed of quarantining and contact tracing with a digital app/centralized system, then you can get it below 1.
Human speech may have a universal transmission rate: 39 bits per second | Science | AAAS
April 14, 2020QT:{{”
Some languages were clearly faster than others: no surprise there. But when the researchers took their final step—multiplying this rate by the bit rate to find out how much information moved per second—they were shocked by the consistency of their results. No matter how fast or slow, how simple or complex, each language gravitated toward an average rate of 39.15 bits per second, they report today in Science Advances. In comparison, the world’s first computer modem (which came out in 1959) had a transfer rate of 110 bits per second, and the average home internet connection today has a transfer rate of 100 megabits per second (or 100 million bits).
