Conditional embedding operator discrepancy
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 ...

WebCDAR then fine-tunes the model using samples from the target domain. In order to fine-tune the model, a new loss function is proposed consisting of a regression loss applied to labeled data and a Conditional Embedding Operator Discrepancy applied to labeled and unlabeled target data. WebFeb 11, 2024 · This paper presents Conditional Contrastive Learning with Kernel (CCL-K) that converts existing conditional contrastive objectives into alternative forms that mitigate the insufficient data problem. Instead of sampling data according to the value of the conditioning variable, CCL-K uses the Kernel Conditional Embedding Operator that …
