Restricted Canonical Correlations
Given a p-dimensional random variable yell and a q-dimensional random variable-y(2) , the first canonical correlation leads to finding Q* E Rp and (3* E R q which maximizes the correlation between Q'y(l) and (3'y(2). However, in many practical situations (e.g. educational testing problems, neural networks), some natural restrictions on the coefficients Q and (3 may arise which should be incorpo...
متن کاملLearning Canonical Correlations
This paper presents a novel learning algorithm that nds the linear combination of one set of multi-dimensional variates that is the best predictor, and at the same time nds the linear combination of another set which is the most predictable. This relation is known as the canonical correlation and has the property of being invariant with respect to a ne transformations of the two sets of variate...
متن کاملMore Canonical Ordering
Canonical ordering is an important tool in planar graph drawing and other applications. Although a linear-time algorithm to determine canonical orderings has been known for a while, it is rather complicated to understand and implement, and the output is not uniquely determined. We present a new approach that is simpler and more intuitive, and that computes a newly defined leftist canonical orde...
متن کاملRestricted, canonical, stereotyped and convergent immunoglobulin responses.
It is becoming evident that B-cell responses to particular epitopes or in particular contexts can be highly convergent at the molecular level. That is, depending on the epitope targeted, persons of diverse genetic backgrounds and immunological histories can use highly similar, stereotyped B-cell receptors (BCRs) for a particular response. In some cases, multiple people with immunity to a partic...
متن کاملRobust Canonical Correlations: a Comparative Study
Several approaches for robust canonical correlation analysis will be presented and discussed. A first method is based on the definition of canonical correlation analysis as looking for linear combinations of two sets of variables having maximal (robust) correlation. A second method is based on alternating robust regressions. These methods are discussed in detail and compared with the more tradi...
