Maxwell Construction: The Hidden Bridge between Iterative and Maximum a Posteriori Decoding
Decoding the decoding algorithm maxwell decoder decoder binary
2015/8/21
There is a fundamental relationship between belief propagation and maximum a posteriori decoding. A decoding algorithm, which we call the Maxwell decoder, is introduced and provides a constructive des...

2014/11/27
This paper extends upon our previous work using i-vectors for speaker diarization. We examine the effectiveness of spectral clustering as an alternative to our previous approach using Kmeans clusterin...
An Efficient Preconditioner for Iterative Solvers
Method of Moments iterative solution LU factorization
2009/7/28
The method of moments solution of the Maxwell's equations leads to a dense system of complex equations. Direct solution of these equations using LU factorization becomes unwieldy as the size of the sc...
