Wavelet techniques and SVM improve bird song classification accuracy

Researchers have developed a new framework for identifying and classifying invasive bird species vocalizations in noisy natural environments. The system utilizes Bayesian wavelet shrinkage with an Epanechnikov kernel for efficient processing of large bioacoustic datasets. After denoising, features like Mel-Frequency Cepstral Coefficients (MFCCs) were extracted and fed into supervised learning models, with Support Vector Machines (SVM) achieving the highest accuracy of up to 0.9398.
