Unifying DAGs and UGs
نویسنده
چکیده
We introduce a new class of graphical models that generalizes Lauritzen-Wermuth-Frydenberg chain graphs by relaxing the semi-directed acyclity constraint so that only directed cycles are forbidden. Moreover, up to two edges are allowed between any pair of nodes. Specifically, we present local, pairwise and global Markov properties for the new graphical models and prove their equivalence. We also present an equivalent factorization property.

A recovery algorithm for chain graphs
The class of chain graphs (CGs) involving both undirected graphs (=Markov networks) and directed acyclic graphs (= Bayesian networks) was introduced in middle eighties for description of probabilistic conditional independence structures. Every class of Markov equivalent CGs (that is, CGs describing the same conditional independence structure) has a natural representative, which is called the la...
متن کاملCompetitive exclusion and coexistence of universal grammars.
Universal grammar (UG) is a list of innate constraints that specify the set of grammars that can be learned by the child during primary language acquisition. UG of the human brain has been shaped by evolution. Evolution requires variation. Hence, we have to postulate and study variation of UG. We investigate evolutionary dynamics and language acquisition in the context of multiple UGs. We provi...

متن کاملThe Application of Unattended Ground Sensors to Human Socio-Cultural Behavior Monitoring
Textron Defense Systems has developed a wide range of unattended ground sensor (UGS) systems for the military and border patrol. These include T-UGS (Tactical UGS), U-UGS (Urban UGS), and most recently the new MicroObserver multimodal UGS system. MicroObserver is characterized by its best-in-class covertness, ease of deployment, negligible false alarm rate, and extremely long battery life (2+ y...
متن کاملDecision Making on Allocating Urban Green Spaces Based upon Spatially-Varying Relationships between Urban Green Spaces and Urban Compaction Degree
The compact city is becoming a prevailing paradigm in the world to control urban sprawl and achieve a pattern of sustainable urban development. However, discussions of the area's overcrowded neighborhoods, its health problems, and the destruction of its green areas have inspired self-examination with respect to the compact city paradigm. High population density attracts even more residents and ...
