A diversifying hidden units method based on NMF for document representation

2016

Document modeling with hidden units as known as topics are very popular. Non-negative matrix factorization(NMF) is one of the most important techniques in document representation, which decomposes a document-term matrix into a document-topic matrix and …

The Cross-Scale Interactive Simulation and Artificial Neural Network Failure Prediction of Temperature Field on Wet Friction Interface

2025 · IEEE Transactions on Instrumentation and Measurement

Aiming at the temperature failure for wet friction interface within mechanical transmissions, this article constructs a single-pair asperities contact model, which considers the influence of rough surface micro-contact states on the wet friction interface temperature …
