An Empirical Evaluation of Model-Based Case Matching and Adaptation

چکیده
Rangeland ecosystems typify physical systems having an incomplete causal theory. This paper describes CARMA, a system for rangeland pest management advising that uses model-based matching and adaptation to integrate case-based reasoning with modelbased reasoning for prediction in rangeland ecosystems. An ablation study showed that removing any part of the CARMA’s model-based knowledge dramatically degraded CARMA’s predictive accuracy. By contrast, any of several prototypical cases could be substituted for CARMA’s full case library without significantly degrading performance. This indicates that the completeness of the model-based knowledge used for matching and adaptation is more important to CAI~MA’s performance than the coverage of the case library.

Evaluation of Similarity Measures for Template Matching
Image matching is a critical process in various photogrammetry, computer vision and remote sensing applications such as image registration, 3D model reconstruction, change detection, image fusion, pattern recognition, autonomous navigation, and digital elevation model (DEM) generation and orientation. The primary goal of the image matching process is to establish the correspondence between two ...
متن کاملRelationship between nutrients and phytoplankton biomass based on chlorophyll prediction model in Zribar Lake of Kurdestan, a case study
Zaribar Lake is a little shallow lake in Kurdistan province of Iran and it is faced to eutrophication.The study of phytoplankton biomass-nutrient relations is important in eutrophication management and there are many empirical models to predict phytoplankton biomass (chlorophyll a) based on nutrient (nitrogen and phosphorous) amounts in the lake. Evaluation of these empirical models and compar...
متن کاملData envelopment analysis in service quality evaluation: an empirical study
Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a sing...
متن کاملFractured Reservoirs History Matching based on Proxy Model and Intelligent Optimization Algorithms
In this paper, a new robust approach based on Least Square Support Vector Machine (LSSVM) as a proxy model is used for an automatic fractured reservoir history matching. The proxy model is made to model the history match objective function (mismatch values) based on the history data of the field. This model is then used to minimize the objective function through Particle Swarm Optimization (...

This paper aims to investigate the effect of budget deficit shock on government spending in Indonesia. For this propose, this reasearch uses an alternative error correction model based on loss function of government spending. The model assumes the short run disequilibrium, in which shock variables may play an important role. A spesific loss function model is applied to develop the long run gove...
