Distortion invariant object recognition in the dynamic link architecture
 IEEE TRANSACTIONS ON COMPUTERS
, 1993
"... We present an object recognition system based on the Dynamic Link Architecture, which is an extension to classical Artificial Neural Networks. The Dynamic Link Architecture exploits correlations in the finescale temporal structure of cellular signals in order to group neurons dynamically into hig ..."

matching cost function. Our implementation on a transputer network successfully achieves recognition of human faces and office objects from gray level camera images. The performance of the program is evaluated by a statistical analysis of recognition results from a portrait gallery comprising images of 87
Monopolistic competition and optimum product diversity. The American Economic Review,
, 1977
"... The basic issue concerning production in welfare economics is whether a market solution will yield the socially optimum kinds and quantities of commodities. It is well known that problems can arise for three broad reasons: distributive justice; external effects; and scale economies. This paper is c ..."

is concerned with the last of these. The basic principle is easily stated.' A commodity should be produced if the costs can be covered by the sum of revenues and a properly defined measure of consumer's surplus. The optimum amount is then found by equating the demand price and the marginal cost
Optimizing Search Engines using Clickthrough Data
, 2002
"... This paper presents an approach to automatically optimizing the retrieval quality of search engines using clickthrough data. Intuitively, a good information retrieval system should present relevant documents high in the ranking, with less relevant documents following below. While previous approaches ..."

Taking a Support Vector Machine (SVM) approach, this paper presents a method for learning retrieval functions. From a
Benchmarking Least Squares Support Vector Machine Classifiers
 NEURAL PROCESSING LETTERS
, 2001
"... In Support Vector Machines (SVMs), the solution of the classification problem is characterized by a (convex) quadratic programming (QP) problem. In a modified version of SVMs, called Least Squares SVM classifiers (LSSVMs), a least squares cost function is proposed so as to obtain a linear set of eq ..."

Efficiency Loss in a Network Resource Allocation Game: The Case of Elastic Supply
, 2008
"... We consider a resource allocation problem where individual users wish to send data across a network to maximize their utility, and a cost is incurred at each link that depends on the total rate sent through the link. It is known that as long as users do not anticipate the effect of their actions on ..."

of their actions on link prices. Under the assumption that the links’ marginal cost functions are convex, we establish existence of a Nash equilibrium. We show that the aggregate surplus at a Nash equilibrium is no worse than a factor of 4 √ 2 − 5 times the optimal aggregate surplus; thus, the efficiency loss when
Sharing the Cost of Multicast Transmissions
, 2001
"... We investigate costsharing algorithms for multicast transmission. Economic considerations point to two distinct mechanisms, marginal cost and Shapley value, as the two solutions most appropriate in this context. We prove that the former has a natural algorithm that uses only two messages per link o ..."

Maximum Lifetime Routing In Wireless Sensor Networks
 IEEE/ACM TRANSACTIONS ON NETWORKING
, 2000
"... Routing in powercontrolled wireless sensor networks is formulated as an optimization problem with the goal of maximizing the system lifetime. Considering that the information is delivered in the form of packets, we identified the problem as an integer programming problem. It is known that the syste ..."

and examined in order to find the best link cost function and the method of shortest path calculation. The performance comparison is made through simulation in a typical battlefield scenario where sensors detecting a moving target vehicle periodically send a reporting packet to one of the gateway nodes
Maximum margin planning
 IN PROCEEDINGS OF THE 23RD INTERNATIONAL CONFERENCE ON MACHINE LEARNING (ICML’06
, 2006
"... Imitation learning of sequential, goaldirected behavior by standard supervised techniques is often difficult. We frame learning such behaviors as a maximum margin structured prediction problem over a space of policies. In this approach, we learn mappings from features to cost so an optimal policy in ..."

Effective Capacity: A Wireless Link Model for Support of Quality of Service
"... To facilitate the efficient support of quality of service (QoS) in nextgeneration wireless networks, it is essential to model a wireless channel in terms of connectionlevel QoS metrics such as data rate, delay and delayviolation probability. However, the existing wireless channel models, i.e., ph ..."

Understanding relationships using copulas
