Transformative Advancements in Fetal Cardiac Health on BiLSTM Networks for FPCG Classification

This article unveils a cutting-edge methodology for Fetal Phonocardiogram (FPCG) classification employing Bidirectional Long Short-Term Memory (BiLSTM) networks. Acknowledging the pivotal role of fetal heart monitoring in early anomaly detection, the research delves into the profound insights offered by FPCG signals concerning fetal cardiac activity. The innovative approach encompasses preprocessing FPCG signals using Mel-Frequency Cepstral Coefficients (MFCC) and spectrogram features, coupled with the strategic application of BiLSTM networks, ensuring a resilient classification framework. The bidirectional nature of the LSTM architecture elevates the model’s ability to capture temporal dependencies in both forward and backward directions, facilitating the discernment of intricate patterns in fetal heart sounds. Experimental findings demonstrate a 98% accuracy, reaffirming the effectiveness and precision of the BiLSTM approach in FPCG classification. This research significantly advances automated methods for evaluating fetal cardiac health, promising transformative enhancements in prenatal care.
