Researchers have explored the effectiveness of different wavelet bases beyond the commonly used Haar and Daubechies for wavelet convolution layers. Their study, focusing on the trade-off between filter length and decomposition levels, found that bases like Coiflets, which have stronger approximation properties, can achieve competitive accuracy with fewer parameters and FLOPs compared to Haar. This suggests that alternative wavelet bases offer a more efficient design choice for practitioners building wavelet-based architectures, particularly in image classification and semantic segmentation tasks.
