Bypassing Logits Bias in Online Class-Incremental Learning with a Generative Framework

no code implementations19 May 2022 Gehui Shen, Shibo Jie, Ziheng Li, Zhi-Hong Deng

In our framework, a generative classifier which utilizes replay memory is used for inference, and the training objective is a pair-based metric learning loss which is proven theoretically to optimize the feature space in a generative way.

A Gap-Based Framework for Chinese Word Segmentation via Very Deep Convolutional Networks

no code implementations27 Dec 2017 Zhiqing Sun, Gehui Shen, Zhi-Hong Deng

However, if we consider segmenting a given sentence, the most intuitive idea is to predict whether to segment for each gap between two consecutive characters, which in comparison makes previous approaches seem too complex.
