Significance Density estimation is among the most fundamental problems in statistics. It notoriously difficult to estimate density of high-dimensional data due “curse dimensionality.” Here, we introduce a new general-purpose estimator based on deep generative neural networks. By modeling normally distributed around manifold reduced dimension, show how power bidirectional networks (e.g., cycleGAN) can be exploited for explicit evaluation density. Simulation and real experiments suggest that...

Aiming at expanding few-shot relations' coverage in knowledge graphs (KGs), graph completion (FKGC) has recently gained more research interests. Some existing models employ a relation's multi-hop neighbor information to enhance its semantic representation. However, noise might be amplified when the neighborhood is excessively sparse and no available represent relation. Moreover, modeling inferring complex relations of one-to-many (1-N), many-to-one (N-1), many-to-many (N-N) by previous...

Unsupervised domain adaptation (UDA) has been received increasing attention since it does not require labels in target domain. Most existing UDA methods learn domain-invariant features by minimizing discrepancy distance computed a certain metric between domains. However, these discrepancy-based cannot be robustly applied to unsupervised time series (UTSDA). That is because metrics contain only low-order and local statistics, which have limited expression for distributions therefore result...
