Markov chain Monte Carlo without the bullshit (2015)
I have a little secret: I don’t like the terminology, notation, and style of writing in statistics. I find it unnecessarily complicated. This shows up when trying to read about Markov Chain Monte Carlo methods. Take, for example, the abstract to the Markov Chain Monte Carlo article in the Encyclopedia of…

AI translates Hokkien, an unwritten language, for the first time
Peng-Jen Chen is well aware of how language barriers can affect people’s ability to communicate. Chen grew up in Taiwan speaking Mandarin Chinese, but his father, Sheng-Jiang Chen, a 70-year-old retired factory lead technician, hails from Southern Taiwan, where Taiwanese Hokkien is widely spoken. Though the two…
