Abstract

Physicians depend on their insight and experience and on a fundamentally indicative or symptomatic approach to decide on the possible ailment of a patient. However, numerous phases of problem identification and longer strategies can prompt a longer time for consulting and can subsequently cause other patients that require attention to wait for longer. This can bring about pressure and tension concerning those patients. In this study, we focus on developing a decision-support system for diagnosing the symptoms as a result of hearing loss. The model is implemented by utilizing machine learning techniques. The Frequent Pattern Growth (FP-Growth) algorithm is used as a feature transformation method and the multivariate Bernoulli naïve Bayes classification model as the classifier. To find the correlation that exists between the hearing thresholds and symptoms of hearing loss, the FP-Growth and association rule algorithms were first used to experiment with small sample and large sample datasets. The result of these two experiments showed the existence of this relationship, and that the performance of the hybrid of the FP-Growth and naïve Bayes algorithms in identifying hearing-loss symptoms was found to be efficient, with a very small error rate. The average accuracy rate and average error rate for the multivariate Bernoulli model with FP-Growth feature transformation, using five training sets, are 98.25% and 1.73%, respectively.

Highlights

  • The main contribution of this work is proposing a model of symptom detection to accurately classify symptoms of hearing loss based on hybrid machine learning approaches, Frequent Pattern Growth (FP-Growth) and naïve Bayes (NB) algorithm, where FP-Growth is an unsupervised method that is used for the feature extraction purpose while the NB

  • The experiments were conducted based on two scenarios: small sample and large sample datasets

  • This study has shown that FP-Growth and association analysis algorithms can be used to uncover the hidden relationships between the hearing-loss symptoms and audiometry thresholds in patients with hearing loss

Summary

Introduction

More than 5 percent (466 million) of the world’s population is affected by hearing loss (432 million adults, 34 million children). It is predicted that over 900 million people, or one out of ten, will experience hearing loss by 2050 [1]. Restricted hearing loss is more than 40 decibels (dB) in the better ear of an adult and more than 30 dB in that of a child. Most people living in low- and middle-income countries suffer from hearing loss [1]. Around a third of people over the age of 65 suffer from disabling hearing loss.
