Probabilistic Visual Learning for Object Representation
, 1996
"... We present an unsupervised technique for visual learning which is based on density estimation in high-dimensional spaces using an eigenspace decomposition. Two types of density estimates are derived for modeling the training data: a multivariate Gaussian (for unimodal distributions) and a Mixture-of ..."

-of-Gaussians model (for multimodal distributions). These probability densities are then used to formulate a maximum-likelihood estimation framework for visual search and target detection for automatic object recognition and coding. Our learning technique is applied to the probabilistic visual modeling, detection
Kernel-Based Object Tracking
, 2003
"... A new approach toward target representation and localization, the central component in visual tracking of non-rigid objects, is proposed. The feature histogram based target representations are regularized by spatial masking with an isotropic kernel. The masking induces spatially-smooth similarity fu ..."

, 1998
"... FrameNet is a three-year NSF-supported project in corpus-based computational lexicography, now in its second year #NSF IRI-9618838, #Tools for Lexicon Building"#. The project's key features are #a# a commitment to corpus evidence for semantic and syntactic generalizations, and #b# the repr ..."

The resulting database will contain #a# descriptions of the semantic frames underlying the meanings of the words described, and #b# the valence representation
Pitch Target Representation of Thai Tones
"... This paper presents a quantitative representation of Thai tones in the form of pitch targets. The optimal pitch targets of Thai tones were estimated by using a combination of the quantitative Target Approximation (qTA) model and a stochastic learning algorithm. With the advent of this technique, the ..."

The reviewing of object files: Object specific integration of information
- Cognitive Psychology
, 1992
"... A series of experiments explored a form of object-specific priming. In all experiments a preview field containing two or more letters is followed by a target letter that is to be named. The displays are designed to produce a perceptual interpretation of the target as a new state of an object that pr ..."

of a reviewing process, which is triggered by the appearance of the target and retrieves just one of the previewed items. In the absence of an object link, the reviewing item is selected at random. We develop the concept of an object file as a temporary episodic representation, within which successive
Adaptive Display Algorithm for Interactive Frame Rates During Visualization of Complex Virtual Environments
, 1993
"... We describe an adaptive display algorithm for interactive frame rates during visualization of very complex virtual environments. The algorithm relies upon a hierarchical model representation in which objects are described at multiple levels of detail and can be drawn with various rendering algorithm ..."

Hierarchical Reinforcement Learning with the MAXQ Value Function Decomposition
- Journal of Artificial Intelligence Research
, 2000
"... This paper presents a new approach to hierarchical reinforcement learning based on decomposing the target Markov decision process (MDP) into a hierarchy of smaller MDPs and decomposing the value function of the target MDP into an additive combination of the value functions of the smaller MDPs. Th ..."

Learning to detect unseen object classes by betweenclass attribute transfer
- In CVPR
, 2009
"... We study the problem of object classification when training and test classes are disjoint, i.e. no training examples of the target classes are available. This setup has hardly been studied in computer vision research, but it is the rule rather than the exception, because the world contains tens of t ..."

Article Performance Analysis of Mobile Laser Scanning Systems in Target Representation
, 2013
"... Abstract: The technology of mobile laser scanning (MLS) has developed rapidly in recent years. This speedy development is evidenced by the emergence of a variety of MLS systems in commercial market and academic institutions. However, the producers tend to supply the specifications of the individual ..."

State Transition Analysis: A Rule-Based Intrusion Detection Approach

The approach, called state transition analysis, models penetrations as a series of state changes that lead from an initial secure state to a target compromised state.
