Given data y and k covariates x one problem in linear regression is to decide which in any of the covariates to include when regressing y on the x. If k is small it is possible to evaluate each subset of the x. If however k is large then some other procedure must be use. Stepwise regression and the lasso are two such procedures but they both assume a linear model with error term. A different ap...

I consider unsupervised extensions of the fast stepwise linear regression algorithm [5]. These extensions allow one to efficiently identify highly-representative feature variable subsets within a given set of jointly distributed variables. This in turn allows for the efficient dimensional reduction of large data sets via the removal of redundant features. Fast search is effected here through th...

Abs t rac t . The notion of institution is dissected into somewhat weaker notions. We introduce a novel notion of institution morphism, and characterize preservation of institution properties by corresponding properties of such morphisms. Target of this work is the stepwise construction of a general framework for translating logics, and algebraic specifications using logical systems. Earlier tr...

Basically, using the phrase “iterative” means there is a stepwise movement towards a (the) goal, instead of a “momentary leap” from problem to solution, where, at intervals, the situation is evaluated and necessary steps are taken to ensure the process is “on track” towards the solution. Such steps will normally be like loops, where you go backwards in the step-line and kind of “run it through ...
