Segmentation of ARX-Models Using Sum-of-Norms Regularization
Segmentation Regularization ARX-models
2015/7/9
Segmentation of time-varying systems and signals into models whose parameters are piecewise constant in time is an important and well studied problem. It is here formulated as a least-squares problem ...
Smoothed state estimates under abrupt changes using sum-of-norms regularization
Smoothing Sparsity Regularization Change detection
2015/7/9
The presence of abrupt changes, such as impulsive and load disturbances, commonly occur in applications, but make the state estimation problem considerably more difficult than in the standard setting ...
On Idempotent D-Norms
Multivariate extreme value theory max-stable distributions max-stable random vectors D-norm generator of D-norm idempotent D-norm D-norm track
2013/4/27
Replacing the spectral measure by a random vector Z allows the representation of a multivariate max-stable distribution with standard negative margins via a norm, called D-norm, whose generator is Z. ...
Approximation properties of certain operator-induced norms on Hilbert spaces
L2 approximation Empirical norm Quadratic functionals Hilbert spaces with reproducing kernels Analysis of M-estimators
2011/6/20
We consider a class of operator-induced norms, acting as finite-dimensional
surrogates to the L2 norm, and study their approximation properties over
Hilbert subspaces of L2. The class includes, as a...
The effects of norms and self-monitoring on helping behavior
norms helping self-monitoring scenario organizational behavior
2009/11/30
A scenario-based experiment was used to test five hypotheses concerning group and
individual predictors of individual intentions to perform helping behavior in a group. The results of an ANCOVA ind...

Knowledge creation cross-functional teams cognitive diversity group dynamics
2009/7/17
This paper contributes to our understanding of the process of knowledge creation in organisations by synthesising contemporary theory across research streams into a comprehensive model of the knowledg...
Situational Influences on Team Helping Norms:Case Study of a Self-directed Team

2009/7/15
A case study investigated the behavioral characteristics of a self-directed work team,
and properties of the team!ˉstask situation that may have influenced team behavior.
Results indicate that hel...
Trust, Norms, and Cooperation:Development and Test of a Simplified Model
Trust Norms Cooperation Simplified Model
2009/7/15
Trust at the interpersonal level in organizational settings has been researched
extensively, yet little has been learned about the process through which trust affects
cooperation and of the role o...
Subjective Norms, Dispositional Trust, and Initial Trust Development
Subjective Norms Dispositional Trust Initial Trust
2009/7/15
A model based on the generally accepted concept of the development of initial trust is tested. Subjective norms are included in the model in addition to dispositional trust and perceptions of the othe...
Social Norms and Sexual Activity in U.S. High Schools
Social Norms Sexual Activity U.S. High Schools
2016/3/4
This paper estimates a formal model of social norms with multiple equilibria using data from the Add-Health Survey of 20,000 U.S. high school students. The results suggest that there is considerable d...
