¤ corresponding author Abstract: We solve the problem of hedging a contingent claim B by maximizing the ex-pected exponential utility of terminal net wealth for a locally bounded semi-martingale X. We prove a duality relation between this problem and a dual problem for local martingale measures Q

In this paper, we borrow the idea of the Receiver Operating Characteristic (ROC) from clinical medicine and demonstrate its application to sequence comparison. The ROC includes elements of both sensitivity and specificity, and is a quantitative measure of the usefulness of a diagnostic. The ROC

We present a source localization method based on a sparse representation of sensor measurements with an overcomplete basis composed of samples from the array manifold. We enforce sparsity by imposing penalties based on the 1-norm. A number of recent theoretical results on sparsifying properties

Motivation: With the development of DNA microarray technology, scientists can now measure the expression levels of thousands of genes simultaneously in one single experiment. One current difficulty in interpreting microarray data comes from their innate nature of “high dimension low sample size

We study various properties of a dynamic convex risk measure for bounded random variables which describe the discounted terminal values of financial positions. In particular we characterize time-consistency by a joint supermartingale property of the risk measure and its penalty function. Moreover

Inter-procedural register allocation can minimize the register usage penalty at procedure calls by reducing the saving and restoring of registers at procedure boun-daries. A one-pass inter-procedural register allocation scheme based on processing the procedures in a depth-first traversal of the cal

-income taxpayers but vary in their ability to reduce marriage penalties. Measuring the Effect of the EITC on Marriage Penalties and Bonuses According to the General Accounting Office (1996), there are 59 provisions in the income tax code that either penalize or reward marriage.1 The presence of marriage penalties

One popular method for the recovery of an ideal intensity image from corrupted or indirect measurements is regularization: minimize an objective function which enforces a roughness penalty in addition to coherence with the data. Linear estimates are relatively easy to compute but generally

the intractable likelihood function for the measured or incomplete data. EM algorithms update all parameters simultaneously, which has two drawbacks: 1) slow convergence, and 2) difficult maximization steps due to coupling when smoothness penalties are used. This paper describes the space-alternating generalized
