[Baps] MIT Skoltech Initiative Seminar: Dr. Boris Khattatov, Tuesday, May 13th 2:30 pm MIT 54-517

[Kerri Cahoy]

Hi All,

I'm hosting Dr. Boris Khattatov tomorrow, and encourage folks to attend his
seminar! (Also let me know if you'd be interested in joining  for lunch or
dinner). I believe Boris has an open slot on his schedule from 10-11 am if
you'd like to meet him outside of lunch/dinner (please e-mailbrettm at mit.edu to
schedule).

Abstract: Arguably, most real-world business and scientific problems on the
intersection of computing, physics and mathematics are ill-posed due to the
lack of accurate observations and/or deficiency of the relevant predictive
models.

Norbert Weiner and Andrey Kolmogorov are perhaps the most well-known
scientists who helped establish a formal mathematical basis for solving
under-determined problems via providing a framework for optimally combining
uncertain theoretical modeling estimates with uncertain observations.

Ruldolf Kalman is universally credited with inventing in 1960 a
computationally efficient algorithm (Kalman filter) for translating this
framework into many practical solutions. This, among other things, helped
to put men on the Moon. The Kalman filter has been embedded in the Apollo
mission navigation computers. Since then, Kalman filters and other
mathematical techniques of estimation theory have been used for achieving
practical solutions to a variety of problems, including weather
forecasting, a problem with a state vector of several million elements.
This talk describes an application of the Kalman filter to assimilative
modeling of the Earth's ionosphere for purposes of increasing accuracy of
routine GPS positioning and aspects of turning the developed solutions into
a business.
