natural image patches what you see is a pattern of kind of features X appearing they end up being oriented edge oriented contour detectors you want something like this is a compositional form of this where the reconstruction now consists in taking a bunch of feature maps those are your latent variables convolving it with a bunch of kernels summing up the results and that's your reconstruction okay so instead of having scaler here you have future maps and instead of having columns of a matrix you have conditional kernels and you get
