Happy E day

E, a.k.a. Euler’s number or the base of the natural logarithm, is near and dear to dynamic modelers. It’s not just the root of exponential growth and decay; thanks to Euler’s Formula it encompasses oscillation, and therefore all things dynamic.

E is approximately 2.718, and today is 2/7/18, at least to Americans, so this is the biggest e day for a while. (NASA has the next 1,999,996 digits, should you need them.) Unlike π, e has not been contested in any state legislature that I know of.

Update to Path Dependence, Competition, and Succession in the Dynamics of Scientific Revolution model

For the 2017 Balaton Group meeting, I’ve updated Sterman & Wittenberg’s Path Dependence, Competition, and Succession in the Dynamics of Scientific Revolution model. The new version is far more usable, with readable variable names and improved diagrams.

This is an extremely interesting model for our current situation of clashing paradigms, fake news and filter bubbles. I encourage you to take a look at the model and paper.

This is actually much more natural as a Ventity model, so watch for another update.

Ad Experiment

In the near future I’ll be running an experiment with serving advertisements on this site, starting with Google AdSense.

This is motivated by a little bit of greed (to defray the costs of hosting) and a lot of curiosity.

  • What kind of ads will show up here?
  • Will it change my perception of this blog?
  • Will I feel any editorial pressure? (If so, the experiment ends.)

I’m generally wary of running society’s information system on a paid basis. (Recall the first deadly sin of complex system management.) On the other hand, there are certainly valid interests in sharing commercial information.

I plan to write about the outcome down the road, but first I’d like to get some firsthand experience.

What do you think?

Update: The experiment is over.

AI babble passes the Turing test

Here’s a nice example of how AI is killing us now. I won’t dignify this with a link, but I found it posted by a LinkedIn user.

I’d call this an example of artificial stupidity, not AI. The article starts off sounding plausible, but quickly degenerates into complete nonsense that’s either automatically generated or translated, with catastrophic results. But it was good enough to make it past someone’s cognitive filters.

For years, corporations have targeted on World Health Organization to indicate ads to and once to indicate the ads. AI permits marketers to, instead, specialize in what messages to indicate the audience, therefore, brands will produce powerful ads specific to the target market. With programmatic accounting for 67% of all international show ads in 2017, AI is required quite ever to make sure the inflated volume of ads doesn’t have an effect on the standard of ads.

One style of AI that’s showing important promise during this space is tongue process (NLP). informatics could be a psychological feature machine learning technology which will realize trends in behavior and traffic an equivalent method an individual’s brain will. mistreatment informatics during this method can match ads with people supported context, compared to only keywords within the past, thus considerably increasing click rates and conversions.

 

Meta MetaSD

I was looking at my google stats the other day, curious what posts interest people most. The answer was surprising. Guess what’s #1?

It’s not “Are Causal Loop Diagrams Useful?” (That’s #2.)

It’s not what I’d consider my best technical work, like Bathtub Statistics or Fun with 1D Vector Fields.

It’s not about something controversial, like On Limits to Growth or The alien hail Mary, and other climate policy plays.

Nor is it a hot topic, like Data science meets the bottom line.

It’s not something practical, like Writing an SD Conference Paper.

#1 is the Fibonacci sequence, How Many Pairs of Rabbits Are Created by One Pair in One Year?

Go figure.
