A Minimax Theorem with Applications to Machine Learning, Signal Processing, and Finance
convex optimization minimax theorem robust optimization
2015/7/9
This paper concerns a fractional function of the form x^Ta/sqrt{x^TBx}, where B is positive definite. We consider the game of choosing x from a convex set, to maximize the function, and choosing (a,B)...

Real-Time Convex Optimization Signal Processing
2015/7/9
Convex optimization has been used in signal processing for a long time, to choose coefficients for use in fast (linear) algorithms, such as in filter or array design; more recently, it has been used t...
Uniform Approximations for the M/G/1 Queue with Subexponential Processing Times
Uniform approximations M/G/1 queue subexponential distributions heavy traffi c heavy tails Cram′er series
2015/7/6
This paper studies the asymptotic behavior of the steady-state waiting time, W∞, of the M/G/1 queue with subexponenential processing times for different combinations of traffic intensities and overflo...
Capturing Data Uncertainty in HighVolume Stream Processing
Data flow system data collection data modeling the sensor data
2014/12/24
We present the design and development of a data stream system that captures data uncertainty from data collection to query processing to final result generation. Our system focuses on data that is nat...
