Researchers have developed S-GAI, a novel initialization framework for sigmoidal MLPs that embeds dataset geometry directly into network weights. This method uses singular value decomposition (SVD) to estimate class-wise spectral geometry from image data, creating initialized hidden layers that are more informative than traditional Xavier initialization. Experiments on MNIST, Fashion-MNIST, and CIFAR-10 demonstrate that S-GAI-initialized models achieve comparable accuracy with less training and even outperform random initializations when the hidden layer is frozen.
