消息传递算法用于信号处理的绝对经典之作，好好学习，天天向上-The message-passing approach to model-based

signal processing is developed with a focus on Gaussian

message passing in linear state-space models, which includes

recursive least squares, linear minimum-mean-squared-error

estimation, and Kalman filtering algorithms. Tabulated message

computation rules for the building blocks of linear models

allow us to compose a variety of such algorithms without

additional derivations or computations. Beyond the Gaussian

case, it is emphasized that the message-passing approach

encourages us to mix and match different algorithmic techniques,

which is exemplified by two different approachesV

steepest descent and expectation maximizationVto message

passing through a multiplier node.
