  expected residual
A method for estimating the expected residual levels would be a useful tool in the assessment of the feasability of bioremediation.
      
The planning horizon obtained (about 4.5 years) appears to be short compared to expected residual lifetime, implying rather small interest elasticities.
      
The expected residual minimization (ERM) formulation for the stochastic nonlinear complementarity problem (SNCP) is studied in this paper.
      
In this paper, we present a statistical framework for detecting degeneracies of a geometric model by evaluating its predictive capability in terms of the expected residual and derive the geometric AIC.
      
These results and the expected residual stress distribution are also compared to the experimentally obtained moiré fringes.

The goal of model selection is to identify the model that generated the data. Goodness of a model is measured using generalizability, which takes two opposite aspects:goodness of fit and model complexity into account, we use generalized Kl-divergence defined on the manifold to measure the goodness of fit, and use the conception of curvature from the point of view of differential geometry to explore the intrinsic model complexity that is free of reparametrization; through theoretical analysis, we proved the future...

The goal of model selection is to identify the model that generated the data. Goodness of a model is measured using generalizability, which takes two opposite aspects:goodness of fit and model complexity into account, we use generalized Kl-divergence defined on the manifold to measure the goodness of fit, and use the conception of curvature from the point of view of differential geometry to explore the intrinsic model complexity that is free of reparametrization; through theoretical analysis, we proved the future residual that is qualified to measure the generalizability can be expressed by using the intrinsic curvature array of model,from which we propose a new model selection criterion KL-divergence and curvature information criterion with very clear and intuitive geometric understanding of model selection. Experimental results reveal its validity.

模型选择的目标就是识别产生给定数据的模型,通常模型的好坏由模型的泛化能力来度量,而泛化能力包含模型对给定数据的拟合度和模型自身复杂度两个方面,本文从信息几何的观点使用定义在流形上的广义KL距离来度量模型的拟合度;另一方面从微分几何的观点用曲率的概念来度量模型的内在复杂度;因此,拟合度和复杂度的表示都具有在参数变换下保持不变的特点,通过理论分析,我们证明了用于表示模型预测能力的未来残差与模型固有曲率的关系,由此提出一种新的基于广义KL距离和曲率的模型选择准则KILCIC.该准则不仅考虑了样本大小、参数个数和函数形式等影响复杂度的因素,而且具有非常清晰直观的几何意义,实验结果表明该方法的有效性.
