This chapter compares Piaget’s theory of development with Feigenbaum and Simon’s (1962, 1984) EPAM theory. An attempt is made to map the concepts of assimilation and accommodation in Piaget’s theory onto the concepts of familiarisation and accommodation in EPAM. An EPAMlike model of the balance scale task is then presented, with a discussion of preliminary results showing how it accounts for ch...
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Road segmentation from remote sensing images is a challenging task with wide ranges of application potentials. Deep neural networks have advanced this field by leveraging the power large-scale labeled data, which, however, are extremely expensive and time-consuming to acquire. One solution use cheap available data train model deploy it directly process specific domain. Nevertheless, well-known ...
The purpose of model selection algorithms such as All Subsets, Forward Selection, and Backward Elimination is to choose a linear model on the basis of the same set of data to which the model will be applied. Typically we have available a large collection of possible covariates from which we hope to select a parsimonious set for the efficient prediction of a response variable. Least Angle Regres...
We study an atom-cavity hybrid system where fermionic atoms in a one-dimensional lattice are subject to cavity-induced dynamic gauge potential. The coupling leads highly degenerate steady states which the fermions accumulate one edge of under open boundary condition. Such phenomenon originates from many-body Liouvillian superoperator system, which, being intrinsically non-Hermitian, is unstable...
This paper proposes a methodology that replaces the usual ad hoc approach to metamodeling. This methodology considers validation of a metamodel with respect to both the underlying simulation model and the problem entity. It distinguishes between ®tting and validating a metamodel, and covers four types of goal: (i) understanding, (ii) prediction, (iii) optimization, and (iv) veri®cation and vali...
