Efficient Heartbeat Analysis Using Neuro-Fuzzy Network and Wavelet Feature Extraction

Problem Definition

The existing literature on artificial neural networks highlights several limitations and challenges that researchers face in achieving improved detection rates. Conventional artificial neural networks have shown effectiveness compared to other approaches, but still have areas where improvements are necessary. One major drawback is the requirement for a large training dataset for neural networks to be utilized effectively. Additionally, the black box nature of neural network architectures poses challenges as their final state cannot be easily interpreted in terms of rules. The learning process itself can be time-consuming and may not guarantee success.

Moreover, traditional classification models face issues related to extracting features from ECG signals, as the conventional techniques for feature extraction may struggle to accurately predict the patient's current state, potentially leading to severe consequences such as death. The proposed model in this paper aims to address these issues by improving the feature extraction process and resolving challenges associated with conventional neural networks.

Objective

The objective of this study is to improve the detection rates of ECG heartbeat abnormalities by addressing the limitations of conventional artificial neural networks. The proposed model aims to enhance feature extraction processes and overcome challenges associated with traditional neural networks through the use of neuro-fuzzy networks. By combining the strengths of neural networks and fuzzy logic, the model plans to achieve high accuracy in identifying ECG abnormalities while ensuring interpretability of the results. Additionally, the model introduces improvements in feature extraction by utilizing DWT-based techniques to extract key features from wavelet-transformed signals. Overall, the objective is to provide a more effective and accurate method for detecting ECG abnormalities compared to traditional approaches.

Proposed Work

In order to overcome the issues identified in traditional approaches to detecting ECG heartbeat abnormalities, this paper proposes a model based on a neuro-fuzzy network. The reasoning behind choosing neuro-fuzzy over a conventional neural network lies in the ability of neuro-fuzzy systems to intelligently combine the strengths of neural networks and fuzzy logic, allowing for more accurate detection of abnormalities. By incorporating the parallel processing, robustness, and data-rich learning capabilities of neural networks with the ability of fuzzy logic to model imprecise and qualitative knowledge and handle uncertainty, the proposed model aims to achieve high accuracy in identifying ECG abnormalities. The use of neuro-fuzzy networks also enables the representation of knowledge in an interpretable manner while optimizing parameters through neural network learning. Additionally, the proposed model introduces improvements in the feature extraction phase by utilizing discrete Wavelet Transform (DWT) based techniques instead of traditional PQRST point localization methods.

This new approach aims to extract features such as mean, standard deviation, maximum and minimum amplitude, and variance from the wavelet transformed signals. By using these features, the model seeks to enhance the accuracy and effectiveness of detecting ECG abnormalities. Overall, the proposed work aims to address the limitations of traditional neural networks, specifically in the context of ECG heartbeat abnormality detection, by leveraging the combined strengths of neuro-fuzzy systems and advanced feature extraction techniques.

By utilizing a neuro-fuzzy network, this model offers a more intelligent decision-making system to detect abnormalities with high accuracy. The integration of neural and fuzzy logic allows for the representation of imprecise knowledge in an interpretable manner while optimizing parameters through neural network learning. Additionally, the use of wavelet feature extraction techniques over traditional PQRST point localization provides more effective feature extraction, including mean, standard deviation, maximum and minimum amplitude with variance.

Implementing these solutions can lead to improved patient care, early detection of cardiac issues, and potentially saving lives in critical situations within various industrial domains.
