Architecture of SOST. The style encoder utilizes strided convolutional layers followed by a global average pooling layer and a fully connected layer. In contrast, the content encoder employs strided convolutional layers alongside residual blocks. In the decoder, a multi-layer perceptron is employed to compute a set of AdaIN parameters based on the style code. Subsequently, the content code is processed through residual blocks with AdaIN layers to achieve cross-domain spectral translation.
