Webφ(y)dP(y x). Unlike the embedding of a single distribution, the embedding of a conditional distribution is not a single element in RKHS, but sweeps out a family of points in the RKHS, each indexed by a fixed value of x. Formally, the embedding of a conditional distribution is represented as an operator C Y X, which satisfies the following ...
WebHere, the embedding is not a single element of the RKHS but rather a family of elements. A particular element of the family is chosen by conditioning on a specific value of x. To obtain the conditional embedding for a specific value of x, Song et al. (2013) additionally introduced the condi-tional embedding operator C YjXas Yjx= C YjX˚(x): (3) WebThis paper presents conditional generative moment matching networks, an extension of GMMNs to conditional generation / prediction applications. The key to the proposed method is the kernel embedding of conditional distributions and conditional MMD metric for measuring discrepancy of conditional distributions.
WebApr 1, 2024 · The operator C Y ∣ X is conventionally used to represent a conditional distribution’s embedding. Also, it should be noted that the embeddings of a conditional distribution are not single elements in the RKHS, rather a family of points, one point for every fixed value of X , is swept out in the RKHS.
