Abstract Bark characteristics are not only used in the forest-wood supply chain, for example to calculate standing volumes, but also transform wood volumes and masses. In this study, bark thickness, volume mass were analyzed on basis of 150 Scots pine discs, with a mean diameter 13 cm. The double thickness was 3.02 mm, proportion 5.6% 3.3%. proportions significantly affected by log-specific var...

Deep regression models are widely employed to solve computer vision tasks, such as human age or pose estimation, crowd counting, object detection, etc. Another possible area of application, which our knowledge has not been systematically explored so far, is proportion judgment. As a prerequisite for successful decision making, individuals often have use judgment strategies, with they estimate t...

Given a 4-tuple of Boolean variables (a, b, c, d), logical proportions are modeled by a pair of equivalences relating similarity indicators (a∧ b and a ∧ b), or dissimilarity indicators (a ∧ b and a ∧ b) pertaining to the pair (a, b), to the ones associated with the pair (c, d). There are 120 semantically distinct logical proportions. One of them models the analogical proportion which correspon...

The Boolean expression of an analogical proportion, i.e., a statement of the form “a is to b as c is to d”, expresses that “a differs from b as c differs from d, and vice-versa. This is the basis of an analogical inference principle, which is shown to be a particular instance of the analogical “jump”: from P (s), P (t), and Q(s), deduceQ(t). Roughly speaking, an analogical proportion sounds lik...

The estimation of proportions is a subject which cannot be circumvented in a first survey sampling course. Estimating the proportion of voters in favour of a political party, based on a political opinion survey, is just one concrete example of this procedure. However, another important issue in survey sampling concerns the proper use of auxiliary information, which typically comes from external...

In this paper, we investigate the problem of face clustering in real-world videos. In many cases, the distribution of the face data is unbalanced. In movies or TV series videos, the leading casts appear quite often and the others appear much less. However, many clustering algorithms cannot well handle such severe unbalance between the data distribution, resulting in that the large class is spli...
