Researchers have developed a new method for image compression using trainable multilinear bases, inspired by quantum many-body theory. These bases, parameterized as isometric tensor networks and optimized on unitary matrices, aim to improve compression efficiency over traditional methods like the Discrete Fourier Transform and Discrete Cosine Transform. The new approach consistently outperforms fixed, non-parametric bases, showing a notable improvement in compressing Quick Draw line drawings by approximately 20% fewer bytes than JPEG at equivalent reconstruction quality.
