Graph Learning From Data Under Laplacian and Structural Constraints
IEEE Journal on Selected Topics in Signal Processing, 2016 Graphs are fundamental mathematical structures used in various fields to represent data, signals, and processes. In this paper, we propose a novel framework for learning/estimating graphs from data.

Image completion via transformation and structural constraints
EURASIP Journal on Image and Video Processing, 2020 Image completion is an approach to fill a damaged region (hole) in an image. In this study, we adopt a novel method which can repair a target region with structural constraints in an architectural scene. An objective function that consists of three terms

Structural constraints for dynamic operators in abstract argumentation
Comma, 2019 Many recent studies of dynamics in formal argumentation within AI focus on the well-known formalism of Dung’s argumentation frameworks (AFs). Despite the usefulness of AFs in many areas of argumentation, their abstract notion of arguments creates a ...

Structural Decompositions for Problems with Global Constraints
, 2015 A wide range of problems can be modelled as constraint satisfaction problems (CSPs), that is, a set of constraints that must be satisfied simultaneously.

Situating peace journalism in journalism studies: A critical appraisal [PDF]
Conflict & Communication Online, 2007 Most wars were not brought to our attention if there were no journalists to report on them and no news media to send reporters to conflict spots. At the same time, the media often give priority to conflict and war at the expense of playing a positive ...

Effects of N-cadherin disruption on spine morphological dynamics
Frontiers in Cellular Neuroscience, 2007 Structural changes at synapses are thought to be a key mechanism for the encoding of memories in the brain. Recent studies have shown that changes in the dynamic behavior of dendritic spines accompany bidirectional changes in synaptic plasticity, and ...

Migration Studies, 2018 The migration literature contends that, unlike other immigrants, refugees resettled in the US benefit from a federal program of integration. These claims do not consider the barriers that may complicate the implementation of resettlement policy. Based on

What causes the word gap? Financial concerns may systematically suppress child-directed speech [PDF]
, 2020 Parents with fewer educational and economic resources (low socioeconomic-status, SES) tend to speak less to their children, with consequences for children’s later life outcomes.

Structural constraints identified with covariation analysis in ribosomal RNA. [PDF]
PLoS ONE, 2012 Covariation analysis is used to identify those positions with similar patterns of sequence variation in an alignment of RNA sequences. These constraints on the evolution of two positions are usually associated with a base pair in a helix.

Exponential Family Matrix Completion under Structural Constraints [PDF]
, 2015 We consider the matrix completion problem of recovering a structured matrix from noisy and partial measurements. Recent works have proposed tractable estimators with strong statistical guarantees for the case where the underlying matrix is low--rank, and
