The Nature of Statistical Learning Theory

by Vladimir N. Vapnik , 1999
"... Statistical learning theory was introduced in the late 1960’s. Until the 1990’s it was a purely theoretical analysis of the problem of function estimation from a given collection of data. In the middle of the 1990’s new types of learning algorithms (called support vector machines) based on the deve ..."

V.: A late fusion approach to cross-lingual document re-ranking

by Dong Zhou, Séamus Lawless, Jinming Min, Vincent Wade - In: Proceedings of the 19th ACM international conference on Information and knowledge management , 2010
"... The field of information retrieval still strives to develop models which allow semantic information to be integrated in the ranking process to improve performance in comparison to standard bagof-words based models. Cross-lingual information retrieval is an example of where such a model is required, ..."

it into the whole corpus. This paper proposes a late fusion method which incorporates scores generated by using external knowledge to enhance the space produced by the latent concept method. This method is further demonstrated to be suitable for multilingual re-ranking purposes. To illustrate the effectiveness

GENIE TRECVID2011 Multimedia Event Detection: Late-Fusion Approaches to Combine Multiple Audio-Visual features

by A. G. Amitha Perera, Sangmin Oh, Matthew Leotta, Ilseo Kim, Byuungki Byun, Chin-hui Lee, Jingchen Liu, Ben Miller, Zhi Feng Huang, Arash Vahdat, Weilong Yang, Greg Mori, Kevin Tang, Daphne Koller, L. Fei-fei, Kang Li, Gang Chen, Jason Corso, Yun Fu, Rohini Srihari
"... For TRECVID 2011 MED task, the GENIE system incorporated two late-fusion approaches where multiple discriminative base-classi ers are built per feature, then, combined later through discriminative fusion techniques. All of our fusion and base classi ers are formulated as one-vs-all detectors per eve ..."

Towards an Active Network Architecture

by David L. Tennenhouse, David J. Wetherall - Computer Communication Review , 1996
"... Active networks allow their users to inject customized programs into the nodes of the network. An extreme case, in which we are most interested, replaces packets with "capsules" -- program fragments that are executed at each network router/switch they traverse. Active architectures permit ..."

a massive increase in the sophistication of the computation that is performed within the network. They will enable new applications, especially those based on application-specific multicast, information fusion, and other services that leverage network-based computation and storage. Furthermore

Trade Liberalization, Exit, and Productivity Improvements: Evidence from Chilean Plants

by Nina Pavcnik - Review of Economic Studies , 2002
"... This paper empirically investigates the effects of liberalized trade on plant productivity in the case of Chile. Chile presents an interesting setting to study this relationship since it underwent a massive trade liberalization that significantly exposed its plants to competition from abroad during ..."

the late 1970s and early 1980s. Methodologically, I approach this question in two steps. In the first step, I estimate a production function to obtain a measure of plant productivity. I estimate the production function semiparametrically to correct for the presence of selection and simultaneity biases

Cumulated Gain-based Evaluation of IR Techniques

by Kalervo Järvelin, Jaana Kekäläinen - ACM Transactions on Information Systems , 2002
"... Modem large retrieval environments tend to overwhelm their users by their large output. Since all documents are not of equal relevance to their users, highly relevant documents should be identified and ranked first for presentation to the users. In order to develop IR techniques to this direction, i ..."
Abstract - Cited by 694 (3 self) - Add to MetaCart
, it is necessary to develop evaluation approaches and methods that credit IR methods for their ability to retrieve highly relevant documents. This can be done by extending traditional evaluation methods, i.e., recall and precision based on binary relevance assessments, to graded relevance assessments

Smooth Stabilization Implies Coprime Factorization

by Eduardo D. Sontag , 1989
"... This paper shows that coprime right factorizations exist for the input to state mapping of a continuous time nonlinear system provided that the smooth feedback stabilization problem be solvable for this system. In particular, it follows that feedback linearizable systems admit such factorizations. I ..."

perturbations analogous to those studied in operator theoretic approaches to systems; it states that smooth stabilization implies smooth input-to-state stabilization. 1 Introduction Constructions of coprime factorizations for nonlinear systems have been obtained of late in the literature ([10], [12], [8

Revised calibration of the geomagnetic polarity timescale for the late Cretaceous and Cenozoic

by S. C. Cande, D. V. Kent - Journal of Geophysical Research , 1995
"... Abstract. Recently reported radioisotopic dates and magnetic anomaly spacings have made it evident hat modification is required for the age calibrations for the geomagnetic polarity timescale of Cande and Kent (1992) at the Cretaceous/Paleogene boundary and in the Pliocene. An adjusted geomagnetic r ..."
Abstract - Cited by 401 (7 self) - Add to MetaCart
reversal chronology for the Late Cretaceous and Cenozoic is presented that is consistent with astrochronology in the Pleistocene and Pliocene and with a new timescale for the Mesozoic. The age of 66 Ma for the Cretaceous/Paleogene (K/P) boundary used for calibration in the geomagnetic polarity timescale

A Survey of Affect Recognition Methods: Audio, Visual, and Spontaneous Expressions

by Zhihong Zeng, Maja Pantic, Glenn I. Roisman, Thomas S. Huang , 2009
"... Automated analysis of human affective behavior has attracted increasing attention from researchers in psychology, computer science, linguistics, neuroscience, and related disciplines. However, the existing methods typically handle only deliberately displayed and exaggerated expressions of prototypi ..."

, an increasing number of efforts are reported toward multimodal fusion for human affect analysis, including audiovisual fusion, linguistic and paralinguistic fusion, and multicue visual fusion based on facial expressions, head movements, and body gestures. This paper introduces and surveys these recent advances
