An Efficient Feedback Coding Scheme With Low Error Probability for Discrete Memoryless Channels
Feedback discrete memoryless channel error exponent
2015/8/12
Existing fixed-length feedback communication schemes are either specialized to particular channels (Schalkwijk–Kailath, Horstein), or apply to general channels but either have high coding complexity (...
Power control in lognormal fading wireless channels with uptime probability specifications via robust geometric programming
Lognormal decline power control wireless transmitter random geometry application geometric programming
2015/8/10
This paper concerns power control in lognormal fading wireless channels with correlated interference. We consider an outage-based quality of service (QoS) specification, which requires the uptime prob...
Learning Probability Measures with respect to Optimal Transport Metrics
Learning Probability Measures Optimal Transport Metrics
2012/11/23
We study the problem of estimating, in the sense of optimal transport metrics, a measure which is assumed supported on a manifold embedded in a Hilbert space. By establishing a precise connection betw...
Facial Shape Localization Using Probability Gradient Hints
Boosting facial shape localization maximum a posteriori estimation probability gradient hints
2013/7/16
This letter proposes a novel method to localize facial shape represented by a series of facial landmarks. In our method, the problem of facial shape localization is formulated with a Bayesian inferenc...
