Learning realistic human actions from movies

by Ivan Laptev, Marcin Marszałek, Cordelia Schmid, Benjamin Rozenfeld - IN: CVPR. , 2008
"... The aim of this paper is to address recognition of natural human actions in diverse and realistic video settings. This challenging but important subject has mostly been ignored in the past due to several problems one of which is the lack of realistic and annotated video datasets. Our first contribut ..."

Uncovering gender discrimination cues in a realistic setting

by N -Roy , I Fortin , D Fiset , F Gosselin , 2009
"... Which face cues do we use for gender discrimination? Few studies have tried to answer this question and the few that have tried typically used only a small set of grayscale stimuli, often distorted and presented a large number of times. Here, we reassessed the importance of facial cues for gender d ..."

discrimination in a more realistic setting. We applied BubblesVa technique that minimizes bias toward specific facial features and does not necessitate the distortion of stimuliVto a set of 300 color photographs of Caucasian faces, each presented only once to 30 participants. Results show that the region

Extending algorithms for mobile robot patrolling in the presence of adversaries to more realistic settings

by Nicola Basilico, Nicola Gatti, Thomas Rossi, Francesco Amigoni - in Proc. IAT , 2009
"... Abstract—Patrolling environments by means of autonomous mobile robots has received an increasing attention in the last few years. The interest of the agent community is mainly in the development of effective patrolling strategies. Approaches based on game theory have been demonstrated to be very eff ..."

effective. They model the patrolling situation as a two-player leader-follower game, where the patroller is the leader and the intruder is the follower. These models present several limitations that prevent their use in realistic settings. In this paper, we extend the most general model from the state

A Theory of the Learnable

by L. G. Valiant , 1984
"... Humans appear to be able to learn new concepts without needing to be programmed explicitly in any conventional sense. In this paper we regard learning as the phenomenon of knowledge acquisition in the absence of explicit programming. We give a precise methodology for studying this phenomenon from ..."

a computational viewpoint. It consists of choosing an appropriate information gathering mechanism, the learning protocol, and exploring the class of concepts that can be learnt using it in a reasonable (polynomial) number of steps. We find that inherent algorithmic complexity appears to set serious

High performance scalable image compression with EBCOT

by David Taubman - IEEE Trans. Image Processing , 2000
"... A new image compression algorithm is proposed, based on independent Embedded Block Coding with Optimized Truncation of the embedded bit-streams (EBCOT). The algorithm exhibits state-of-the-art compression performance while producing a bit-stream with a rich feature set, including resolution and SNR ..."

The SPLASH-2 programs: Characterization and methodological considerations

by Steven Cameron Woo, Moriyoshi Ohara, Evan Torrie, Jaswinder Pal Singh, Anoop Gupta - INTERNATIONAL SYMPOSIUM ON COMPUTER ARCHITECTURE , 1995
"... The SPLASH-2 suite of parallel applications has recently been released to facilitate the study of centralized and distributed shared-address-space multiprocessors. In this context, this paper has two goals. One is to quantitatively characterize the SPLASH-2 programs in terms of fundamental propertie ..."

sets of the applications, we describe which operating points in terms of cache size and problem size are representative of realistic situations, which are not, and which re redundant. Using SPLASH-2 as an example, we hope to convey the importance of understanding the interplay of problem size, number

Generating Representative Web Workloads for Network and Server Performance Evaluation

by Paul Barford, Mark Crovella , 1997
"... One role for workload generation is as a means for understanding how servers and networks respond to variation in load. This enables management and capacity planning based on current and projected usage. This paper applies a number of observations of Web server usage to create a realistic Web worklo ..."

A Simple, Fast, and Accurate Algorithm to Estimate Large Phylogenies by Maximum Likelihood

by Stéphane Guindon, Olivier Gascuel , 2003
"... The increase in the number of large data sets and the complexity of current probabilistic sequence evolution models necessitates fast and reliable phylogeny reconstruction methods. We describe a new approach, based on the maximumlikelihood principle, which clearly satisfies these requirements. The ..."

PDDL2.1: An Extension to PDDL for Expressing Temporal Planning Domains

by Maria Fox, Derek Long , 2003
"... In recent years research in the planning community has moved increasingly towards application of planners to realistic problems involving both time and many types of resources. For example, interest in planning demonstrated by the space research community has inspired work in observation scheduling, ..."

Image scoring in ad-hoc networks: An investigation on realistic settings

by Henry Franks, Nathan Griffiths, Arshad Jhumka
"... Abstract. Encouraging cooperation in distributed Multi-Agent Systems (MAS) remains an open problem. Emergent application domains such as Mobile Ad-hoc Networks (MANETs) are characterised by constraints including sparse connectivity and a lack of direct interaction history. Image scoring, a simple mo ..."

promising technique for adhoc networking domains. However, the original investigation of Nowak and Sigmund is limited in that it (i) used a simple idealised setting, (ii) did not consider the effects of incomplete information on the mechanism’s efficacy, and (iii) did not consider the impact of the network
