  15. The Kalman Filter has been one of the toughest concepts for me to grasp over the years. I have looked at many examples related to target tracking, which logically makes sense to me given physical behavior of flying targets. But can anyone provide more applications that make learning the Kalman Filter easy? I recommend the following two articles that helped me get a better working understanding of the Kalman Filter:…

There are more like you describe out there, though they tend to be scattered around the Internet. https://jvns.ca/ often gets mentioned on HN and has a large volume of posts that follow the format "let's assume both you and I don't know anything - how do we figure this out?". http://jamie-wong.com/ , a coworker, has a few good ones on graphics/numerical stuff.

  27. Congrats on the launch nextmv! I had a chance to play with nextmv's beta when they first published it. By far the most useful aspect was the ability to bracket the decision results by calculation time. E.g., I can say, give me your best result of this choice given 100ms. This changes the typical "train / test / deploy" ML process, to something where you can get as accurate a result as possible given some block of ti…
