The proposed “learnable” Multiresolution Matrix Factorization (MMF) algorithm optimizes the factorization using metaheuristics, specifically evolutionary algorithms and directed evolution, along with Stiefel manifold optimization through backpropagating errors. This approach outperforms prior MMF algorithms and achieves comparable performance on standard learning tasks on graphs. The wavelet basis produced by this algorithm is used to construct Wavelet Neural Networks (WNNs) that learn graphs in the spectral domain. These WNNs are competitive with state-of-the-art methods in molecular graph classification and node classification on citation graphs.

Multiresolution Matrix Factorization (MMF) is a new way to model complex patterns in data. This algorithm doesn’t make assumptions about how much information is important, making it good for finding patterns that change at different scales. The problem is that finding the right factors is hard. To solve this, the researchers used special techniques called metaheuristics and optimized the factors using these methods. They showed that their approach works well on graphs and can be used to build powerful neural networks. These networks are good at recognizing patterns in molecular data and citation networks.
