Genuine question: why does kalman filter come up so frequently on HN? Is this something I'm missing? I'm a machine learning engineer, not a data scientist.
Some theories even suggest that Kalman filtering (or a similar algorithm) provides a basis for neurobiological learning. See predictive coding (e.g. https://arxiv.org/pdf/2102.10021.pdf)
(Why I'm interested in it, at least.)
A similar thing happens that had the word quantic or relativistic. I'm a physicist and we hardly talk about it, but here in HN we find people bringing in up every other day
