CCPrefix: Counterfactual Contrastive Prefix-Tuning for Many-Class Classification

no code implementations11 Nov 2022 Yang Li, Canran Xu, Guodong Long, Tao Shen, Chongyang Tao, Jing Jiang

Basically, an instance-dependent soft prefix, derived from fact-counterfactual pairs in the label space, is leveraged to complement the language verbalizers in many-class classification.

Hierarchical Character Tagger for Short Text Spelling Error Correction

no code implementations WNUT (ACL) 2021 Mengyi Gao, Canran Xu, Peng Shi

State-of-the-art approaches to spelling error correction problem include Transformer-based Seq2Seq models, which require large training sets and suffer from slow inference time; and sequence labeling models based on Transformer encoders like BERT, which involve token-level label space and therefore a large pre-defined vocabulary dictionary.
