Modular neural network model based foetal state classification

Abstract

Cardiotocography (CT G) is a simultaneous recording of foetal heart rate (F HR) and uterine contractions (UC) and it is one of the most common diagnostic techniques to evaluate maternal and foetal well-being during pregnancy and before delivery. Assessment of the foetal state can be verified only after delivery using the foetal (newborn) outcome data. One of the most important features defining the abnormal foetal outcome is low birth weight. This paper proposes a multi-class classification algorithm using Modular neural network (MNN) models. It tries to boost two conflicting main objectives of multiclass classifiers: a high correct classification rate level and a high classification rate for each class. Using a Cardiotocography database of normal, suspect and pathological cases, we trained MNN classifiers with 23 real valued diagnostic features collected from total 2126 foetal CTG signal recordings data from UCI Machine Learning Repository. We used the classification in a detection process. The proposed methodology is presented, which then is tested on UCI Cardiotocography unseen testing data sets. Experimental results are promising paving the way for further research in that direction.

Genetic Algorithm Based Feature Subset Selection for Fetal State Classification

“…Subject to the constraints (8) It is a well-known fact that SVM is meant for only classification into two classes [16]. By constructing and combining several binary classifiers, an n-class SVM can be designed.…”

“…Naïve Bayes Classifier has been used for classification of CTG data along with feature selection approaches in [7]. In [8], a classifier has been proposed which classifies the data into three classes by applying modular neural network. A neural network based classifier has been presented in [9], to improve the performance of clustering algorithms in CTG classification.…”

Artificial Neural Network Models based Cardiac Arrhythmia Disease Diagnosis from ECG Signal Data

“…An Artificial immune recognition system (AIRS) with fuzzy weighted preprocessing [18] is also used for arrhythmia classification. Multilayer perceptron model and Modular neural network model is applied in [19] and [20] respectively for multiclass ECG arrhythmia and fetal state classification problems. Various neural network models are used to classify ECG arrhythmia and classification accuracies are reported in [21][22][23][24].…”

ANN-based approach to model MC/DR of some fruits under solar drying

“…However, in the testing stage, a different set of data containing only input values is fed to the network. 23 Several configurations were studied through the application of the feed-forward back-propagation network in the modelling of the drying process. Selecting the input variables is one of the most important steps during the design and training phases of an ANN.…”
