We study similarity in formal concept analysis of data tables with graded attributes. We focus on similarity related to formal concepts and concept lattices, i.e. the outputs of formal concept analysis. We present several formulas for estimation of similarity of outputs in terms of similarity of inputs. The results answer some problems which arose in previous investigation as well as some natur...

Abstruct-This paper proposes algorithms for reconstructing convex sets given noisy support line measurements. We begin by observing that a set of measured support lines may not be consistent with any set in the plane. We then develop a theory of consistent support lines which serves as a basis for reconstruction algorithms that take the form of constrained optimization algorithms. The formal st...

Three-dimensional structure information can be estimated from two-dimensional images using recursive estimation methods. This paper investigates possibilities to improve structure filter performance for a certain class of stochastic perspective systems by utilizing mutual information, in particular when each observed point on a rigid object is affected by the same process noise. After presentin...

in the almost new literature of social capital, the concept has mainly been considered domestic, while we can find social capital beyond state borders. in this article social capital has been connected to international relations through micro and macro aspects. the effect of information technology on social capital is then mentioned on both domestic and transnational scales. information technol...

one of the most important aspects of software project management is the estimation of cost and time required for running information system. therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. software cost estimation refers to the process of development requirement prediction of software system. various kinds of effort estimation patter...

Permeability plays an important role in subsurface fluid flow studies, being one of the most important quantities for the prediction of fluid flow patterns. The estimation of permeability fields is therefore critical and necessary for the prediction of the behavior of contaminant plumes in aquifers and the production of petroleum from oil fields. In the particular case of production of petroleu...

Robust design optimization methods applied to real life problems face some major difficulties: how to deal with the estimation of probability densities when data are sparse, how to cope with high dimensional problems and how to use valuable information in the form of unformalized expert knowledge. We introduce the clouds formalism as means to process available uncertainty information reliably, ...

Approximate logic synthesis techniques have become popular in error-resilient systems, where accuracy requirements can be traded for improved energy efficiency. Many of these operate on a circuit by substituting or removing some its portions under predefined error constraint; however, the research systematic methods to determine induced such transformations is still at an early stage. We propos...
