The Impact Of Outsourcing And High-Technology Capital On Wages: Estimates For The United States, 1979-1990
, 1998
"... We estimate the relative influence of trade versus technology on wages in a "large country" setting, where technological change affects product prices. Trade is measured by the foreign outsourcing of intermediate inputs, while technological change is measured by expenditures on high-techno ..."

We estimate the relative influence of trade versus technology on wages in a "large country" setting, where technological change affects product prices. Trade is measured by the foreign outsourcing of intermediate inputs, while technological change is measured by expenditures on high
Static Scheduling of Synchronous Data Flow Programs for Digital Signal Processing
- IEEE TRANSACTIONS ON COMPUTERS
, 1987
"... Large grain data flow (LGDF) programming is natural and convenient for describing digital signal processing (DSP) systems, but its runtime overhead is costly in real time or cost-sensitive applications. In some situations, designers are not willing to squander computing resources for the sake of pro ..."

flow (SDF) differs from traditional data flow in that the amount of data produced and consumed by a data flow node is specified a priori for each input and output. This is equivalent to specifying the relative sample rates in signal processing system. This means that the scheduling of SDF nodes need
Policy gradient methods for reinforcement learning with function approximation.
- In NIPS,
, 1999
"... Abstract Function approximation is essential to reinforcement learning, but the standard approach of approximating a value function and determining a policy from it has so far proven theoretically intractable. In this paper we explore an alternative approach in which the policy is explicitly repres ..."

First, it is oriented toward finding deterministic policies, whereas the optimal policy is often stochastic, selecting different actions with specific probabilities (e.g., see In this paper we explore an alternative approach to function approximation in RL. Rather than
Robust Anisotropic Diffusion
, 1998
"... Relations between anisotropic diffusion and robust statistics are described in this paper. Specifically, we show that anisotropic diffusion can be seen as a robust estimation procedure that estimates a piecewise smooth image from a noisy input image. The "edge-stopping" function in the ani ..."

Information-theoretic metric learning
- in NIPS 2006 Workshop on Learning to Compare Examples
, 2007
"... We formulate the metric learning problem as that of minimizing the differential relative entropy between two multivariate Gaussians under constraints on the Mahalanobis distance function. Via a surprising equivalence, we show that this problem can be solved as a low-rank kernel learning problem. Spe ..."

. Specifically, we minimize the Burg divergence of a low-rank kernel to an input kernel, subject to pairwise distance constraints. Our approach has several advantages over existing methods. First, we present a natural information-theoretic formulation for the problem. Second, the algorithm utilizes the methods
Self-organisation in a perceptual network
- IEEE Computer
, 1988
"... young animal or child perceives and identifies features in its envi-, roument in an apparently effortless way. No presently known algorithms even approach this flexible, generalpurpose perceptual capability. Discovering the principles that may underlie perceptual processing is important both for neu ..."

Two important aspects of the mystery of perception are (1) What processing functions does the neural “machinery ” perform on perceptual input, and what is the circuitry that implements these functions? (2) How does this “machinery ” come
Global Sourcing
- Journal of Political Economy
"... We present a North-South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. On the basis of productivity and sectoral characteristics, firms decide whether to integrate into the pr ..."

Final-good producers and their suppliers must make relationship-specific investments, both in an integrated firm and in an arm’s-length relationship. We describe an equilibrium
The Tradeoffs Between Open and Traditional Relation Extraction
"... Traditional Information Extraction (IE) takes a relation name and hand-tagged examples of that relation as input. Open IE is a relationindependent extraction paradigm that is tailored to massive and heterogeneous corpora such as the Web. An Open IE system extracts a diverse set of relational tuples ..."

The goal is to develop a sound method of quan-tifying how investments in educational quality relate to outcomes. Once we are able to put a dollar value on improvements in school quality, we can compare policy
Stability, queue length and delay of deterministic and stochastic queueing networks

, 1994

Motivated by recent development in high speed networks, in this paper we study two types of stability problems: (i) conditions for queueing networks that render bounded queue lengths and bounded delay for customers, and (ii) conditions for queueing networks in which the queue length distribution of ..."
