and artificial intelligence may be viewed as instances of the summary-product algorithm (or belief/probability propagation algorithm), which operates by message passing in a graphical model. Specific instances of such algorithms include Kalman filtering and smoothing; the forward–backward algorithm for hidden Markov models; probability propagation in Bayesian networks; and decoding algorithms f...

iology is evolving into an informationrich science due to advances in highthroughput (large scale) experimental techniques that produce hundreds of thousands of data points in a single measurement. The field of computational functional genomics exploits this wealth of information to create models that begin to describe function in a systematic way. A fundamental aspect of computational function...

Electromagnetic brain mapping - IEEE Signal Processing Magazine

seen tremendous advances in our ability to produce images of human brain function. Applications of functional brain imaging extend from improving our understanding of the basic mechanisms of cognitive processes to better characterization of pathologies that impair normal function. Magnetoencephalography (MEG) and electroencephalography (EEG) (MEG/EEG) localize neural electrical activity using n...

Fractionally Spaced Equalizers - IEEE Signal Processing Magazine

odern digital transmission systems commonly use an adaptive equalizer as a key part of the receiver. The design of this equalizer is important since it determines the maximum quality attainable from the system, and represents a high fraction of the computation used to implement the demodulator. Recent analytical results offer a new way of looking at fractionally spaced equalizers and have some ...
