Bayesian-driven Multi-layer Perceptron Applied to Liver Fibrosis Stadialization
نویسندگان
چکیده
This paper proposes the application to the liver fibrosis stadialization of a novel training technique of feed-forward neural networks based on the Bayesian paradigm. Using the Pearson’s r correlation coefficient instead of the standard backpropagation algorithm to update the synaptic weights of a multi-layer perceptron, the proposed model is compared with traditional machine learning algorithms (standard MLP, RBF, PNN, SVM) using a real-life liver fibrosis dataset. The statistical comparison results indicated that the Bayesian-trained MLP proved to be at least as efficient as its classic competitors.

Bayesian regularisation methods in a hybrid MLP-HMM system
We have applied Bayesian regularisation methods to multi-layer perceptron (MLP) training in the context of a hybrid MLP– HMM (hidden Markov model) continuous speech recognition system. The Bayesian framework adopted here allows an objective setting of the regularisation parameters, according to the training data. Experiments were carried out on the ARPA Resource Management database.
متن کاملNode Relevance Determination
Hierarchical Bayesian inference in parameterised models offers an approach for controlling complexity. In this paper we utilise a novel prior for the leaning of a model’s structure. We call the prior node relevance determination. It is applicable in a range of models including sigmoid belief networks and Boltzmann machines. We demonstrate how the approach may be applied to determine structure i...

Surface soil moisture is an important variable that plays a crucial role in the management of water and soil resources. Estimating this parameter is one of the important applications of remote sensing. One of the remote sensing techniques for precise estimation of this parameter is data-driven models. In this study, volumetric soil moisture content was estimated using data-driven models, suppor...
متن کاملMulti-Layer Perceptrons as Nonlinear Generative Models for Unsupervised Learning: a Bayesian Treatment
In this paper, multi-layer perceptrons are used as nonlinear generative models. The problem of indeterminacy of the models is resolved using a recently developed Bayesian method called ensemble learning. Using a Bayesian approach, models can be compared according to their probabilities. In simulations with artiicial data, the network is able to nd the underlying causes of the observations despi...
متن کاملNew full adders using multi-layer perceptron network
How to reconfigure a logic gate for a variety of functions is an interesting topic. In this paper, a different method of designing logic gates are proposed. Initially, due to the training ability of the multilayer perceptron neural network, it was used to create a new type of logic and full adder gates. In this method, the perceptron network was trained and then tested. This network was 100% ac...
