We propose a multivariate decision tree inference scheme by using the minimum message length (MML) principle (Wallace and Boulton, 1968; Wallace and Dowe, 1999). The scheme uses MML coding as an objective (goodness-of-fit) function on model selection and searches with a simple evolution strategy. We test our multivariate tree inference scheme on UCI machine learning repository data sets and com...

In 1907 Hagge constructed a circle associated with each cevian point P of triangle ABC. If P is on the circumcircle this circle degenerates to a straight line through the orthocenter which is parallel to the Wallace-Simson line of P . We give a new proof of Hagge’s result by a method based on reflections. We introduce an axis associated with the construction, and (via an areal analysis) a conic...

We are much indebted to Dr. Sim Wallace for giving us a book from his able contributions which have appeared from time to time in the Journal of the British Dental Association on " The Etiology of Dental Caries." The headings of the chapters are sufficient to show how carefully and exhaustively he has gone into the subject, and it is not too much to say that it is a work that ought to be in the...

In some respects natural selection is a quite simple theory, arrived at through the logical integration of three propositions (the presence of variation within natural populations, an absolutely limited resources base, and procreation capacities exceeding mere replacement numbers) whose individual truths can hardly be denied. Its relation to the larger subject of evolution, however, remains pro...

A problem, raised by Wallace (JASIS, 37, 136-145, 1986), on the relation between the journal's median citation age and its number of articles is studied. Leaving open the problem as such, we give a statistical explanation of this relationship, when replacing "median" by "mean" in Wallace's problem. The cloud of points, found by Wallace, is explained in this sense that the points are scattered o...

It is proved that if A is an abelian p-group with a pure subgroup G so that A/G is at most countable and G is either p-totally projective or p-summable, then A is either p-totally projective or p-summable as well. Moreover, if in addition G is nice in A, then G being either strongly p-totally projective or strongly p-summable implies that so is A. This generalizes a classical result of Wallace ...

This paper proposes a novel recursive structure block-based Wallace tree multiplier with the capability to tune its accuracy based on the precision and power requirements. The multiplier performs multiplication operations recursively from small blocks to large blocks, with a fine grain capability of turning off small blocks to trade off with power. By tuning the fidelity design “knob”, we show ...
