Research on Dual Channel News Headline Classification Based on ERNIE Pre-training Model

no code implementations14 Feb 2022 Junjie Li, Hui Cao

Aiming at the problem that the traditional neural network model cannot adequately capture the underlying feature information of the data and cannot jointly extract key global features and deep local features, a dual-channel network model DC-EBAD based on the ERNIE pre-training model is proposed.


Low-confidence Samples Matter for Domain Adaptation

1 code implementation6 Feb 2022 Yixin Zhang, Junjie Li, Zilei Wang

Representing the target data structure in such a way would overlook the huge low-confidence samples, resulting in sub-optimal transferability that is biased towards the samples similar to the source domain.
