From Correspondence Analysis to Multiple and Joint Correspondence Analysis
The generalization of simple (two-variable) correspondence analysis to more than two categorical variables, commonly referred to as multiple correspondence analysis, is neither obvious nor well-defined. We present two alternative ways of generalizing correspondence analysis, one based on the quantification of the variables and intercorrelation relationships, and the other based on the geometric...
متن کاملAlgebras from AdS / CFT Correspondence
We consider a system of D5/D1 branes in the supergravity background AdS3 × S ×X , where X is T 4 or K3. By investigating the structure of the missing states in the conformal description, we are able to extend the AdS/CFT correspondence to W algebras. As a test of this new formulation the results are compared to Hilbert schemes and more general supergravity backgrounds as deformations by D3-bran...
متن کاملSemantic Structure from Correspondence Analysis
A common problem for clustering techniques is that clusters overlap, which makes graphing the statistical structure in the data difficult. A related problem is that we often want to see the distribution of factors (variables) as well as classes (objects). Correspondence Analysis (CA) offers a solution to both these problems. The structure that CA discovers may be an important step in representi...
متن کاملStructure from Motion without Correspondence
A method is presented to recover 3D scene structure and camera motion from multiple images without the need for correspondence information. The problem is framed as finding the maximum likelihood structure and motion given only the 2D measurements, integrating over all possible assignments of 3D features to 2D measurements. This goal is achieved by means of an algorithm which iteratively refine...
متن کاملCoping with suicide: a perspective from Scotland
Procedures following suicide differ in Scotland from elsewhere in the UK and we describe the investigation of deaths by procurators fiscal and fatal accident inquiries that may ensue. Higher Scottish suicide rates, and possible reasons for these, are mentioned. Suicide risk cannot be accurately quantified in individual patients but psychiatrists should take the view that good management can col...
