Action snippets: How many frames does human action recognition require
- In CVPR
, 2008
"... Visual recognition of human actions in video clips has been an active field of research in recent years. However, most published methods either analyse an entire video and assign it a single action label, or use relatively large lookahead to classify each frame. Contrary to these strategies, human v ..."

Progressive search space reduction for human pose estimation
- In CVPR
, 2008
"... The objective of this paper is to estimate 2D human pose as a spatial configuration of body parts in TV and movie video shots. Such video material is uncontrolled and extremely challenging. We propose an approach that progressively reduces the search space for body parts, to greatly improve the chan ..."

We demonstrate upper-body pose estimation by an extensive evaluation over 70000 frames from four episodes of the TV series Buffy the vampire slayer, and present an application to fullbody action recognition
Situated action: a symbolic interpretation
- Cognitive Science
, 1993
"... The congeries of theoretical views collectively referred to as "situated action" (SA) claim that humans and their interactions with the world cannot be understood using symbol-system models and methodology, but only by observing them within real-world contexts or building nonsymbolic model ..."

The action similarity labeling challenge
- IEEE TRANSACTIONS OF PATTERN ANALYSIS AND MACHINE INTELLIGENCE (TPAMI
, 2011
"... Recognizing actions in videos is rapidly becoming a topic of much research. To facilitate the development of methods for action recognition, several video collections, along with benchmark protocols, have previously been proposed. In this paper we present a novel video database, the “Action Similari ..."

Our benchmark protocols focus on action similarity (same/not-same), rather than action classification, and testing is performed
Intrusion detection with unlabeled data using clustering
- In Proceedings of ACM CSS Workshop on Data Mining Applied to Security (DMSA-2001
, 2001
"... Abstract Intrusions pose a serious security risk in a network environment. Although systems can be hardened against many types of intrusions, often intrusions are successful making systems for detecting these intrusions critical to the security of these system. New intrusion types, of which detectio ..."

detection systems are unaware, are the most difficult to detect. Current signature based methods and learning algorithms which rely on labeled data to train, generally can not detect these new intrusions. In addition, labeled training data in order to train misuse and anomaly detection systems is typically
When is an illustration worth ten thousand words
- Journal of Educational Psychology
, 1990
"... In three experiments, students read expository passages concerning how scientific devices work, which contained either no illustrations (control), static illustrations of the device with labels for each part (parts), static illustrations of the device with labels for each major action (steps), or dy ..."

Behavioral theories and the neurophysiology of reward,
- Annu. Rev. Psychol.
, 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."
