Committee Networks by Resampling
نویسندگان
چکیده
Artificial neural networks (ANN) are nonparametric models and like all nonparametric models require a large number of observations to build and evaluate the model. But data is always finite and most often scarce in real world applications. The question now becomes: How does a modeler build an ANN model on a limited sample size and obtain an accurate and reliable estimate the model’s error? The research presented in this paper proposes a novel method for building and evaluating ANN under the condition of scarce data: Committee networks by resampling.

Improving Committee Diagnosis with Resampling Techniques
Central to the performance improvement of a committee relative to individual networks is the error correlation between networks in the committee. We investigated methods of achieving error independence between the networks by training the networks with different resampling sets from the original training set. The methods were tested on the sinwave artificial task and the real-world problems of ...
متن کاملSequential Importance Sampling Based on a Committee of Artificial Neural Networks for Posterior Health Condition Estimation
The output of real-time diagnostic systems based on the interpretation of signals from a sensor network is often affected by very large uncertainties if compared with local nondestructive testing methods. Sequential Importance Resampling (SIR) is used in this study to filter the output distribution from a committee of Artificial Neural Networks. The methodology is applied to a helicopter panel ...

As one of the important energy forms, natural gas consumption has an upward trend in recent years. Therefore management and planning for provision of it requires prediction of the future consumption. But many of prediction procedures are inherently stochastic therefore it is important to have better knowledge about the robustness of prediction procedures. This paper compares robustness of two p...
متن کاملResampling-based selective clustering ensembles
Traditional clustering ensembles methods combine all obtained clustering results at hand. However, we observe that it can often achieve a better clustering solution if only part of all available clustering results are combined. This paper proposes a novel clustering ensembles method, termed as resampling-based selective clustering ensembles method. The proposed selective clustering ensembles me...
متن کاملA Multiple classifier system for fast an accurate learning in neural network context
Nowadays, the Multiple Classification Systems (MCS) (also called as ensemble of classifiers, committee of learners and mixture of experts) constitutes a well-established research field in Pattern Recognition and Machine Learning. The MCS consists in dividing the whole problem with resampling methods, or using different models for constructing the system over a single data set. A similar approac...
