in this paper, we consider the production possibility set with n production units such that the following four principles that governs: inclusion observations, conceivability, immensity and convexity. our goal is to estimate the output of a same and new production unit with existing production possibility and amount of input is specified. so, initially we find the interval changes of each input...

While ensembles have been used for structured output learning, the literature lacks an extensive study of different strategies to construct ensembles in this context. In this work, we fill this gap by presenting a thorough empirical comparison of ensembles that predict the complete output structure at once, versus a combination of ensembles that each predicts a single component of the structure...

Users are known to experience difficulties in dealing with information retrieval search outputs, especially if those outputs are above a certain size. It has been argued by several researchers that search output clustering can help users in their interaction with IR systems in some retrieval situations, providing them with an overview of their results by exploiting the topicality information th...
