I'm always surprised when people talk about Kalman filters without mentioning the killer app, which is weather prediction. Quite a few weather prediction organisations are at least experimenting with Kalman filters, and some are running whole ensemble forecasts using the method. It may sound strange, but the Kalman filter can be a less CPU-intensive (or at least more parallelisable) way of calculating atmospheric state than the current variational data assimilation methods.
- tnecniv 10y agoThat's an interesting application that I didn't consider, but I'd say the real killer app was the fact that it helped put a man on the moon...
- zbuf 10y agoThe reason the Kalman filter is so significant is that there isn't a standout "killer app"; there's a whole bunch of them. It's much more fundamental than any of its applications, which are all around us.
