Conditional mean embedding
WebWe present an operator-free, measure-theoretic approach to the conditional mean embedding (CME) as a random variable taking values in a reproducing kernel Hilbert space. While the kernel mean embedding of unconditional distributions has been defined rigorously, the existing operator-based approach of the conditional version depends on … Web2009). In this formulation the conditional expectation of any function fin the RKHS becomes a linear oper-ation, via the RKHS inner product with the appropriate distribution embedding. Conditional mean embeddings have been successfully applied to many machine learning tasks such as hidden Markov models (Song et al., 2010a),

WebThe authors propose a measure-theoretic approach to formulating conditional mean embeddings, in contrast to the operator approach currently within the kernel mean … Web3.1 Conditional Mean Embeddings We begin with an overview of CMEs in the context of KELFI. Kernel mean embeddings (KMEs) are an arsenal of techniques used to represent distributions in a RKHS (Muandet et al., 2024). The key object is the mean embedding of a distribution X P under a positive de nite kernel k via X:= R X R k (x; )dP (x ) = X

Webwe note that the conditional mean embedding [56] is the solution to a regression problem [34, 35, 33], and thus equivalent to kernel dependency estimation [20, 21]. We prove that the kernel estimator of the conditional mean embedding (equivalently, the conditional expectation operator) converges in RKHS-norm, generalizing classic results by [53 ... http://auai.org/~w-auai/uai2024/proceedings/469_main_paper.pdf
