CLUES: A Benchmark for Learning Classifiers using Natural Language Explanations (2022.acl-long)
Copied to clipboard
| Challenge: | Supervised learning has traditionally focused on inductive learning by looking at labeled examples of a task. |
| Approach: | They propose a benchmark for Classifier Learning Using natural language ExplanationS that provides natural language supervision over structured data and entailment-based models that learn from explanations. |
| Outcome: | The proposed model generalizes 18% better (relative) on novel tasks than a baseline that does not use explanations. |
Improving and Simplifying Pattern Exploiting Training (2021.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have shown that pre-trained language models can learn well when primed with only a few labeled examples. |
| Approach: | They propose a method that uses task-specific unlabeled data to provide denser supervision during fine-tuning. |
| Outcome: | The proposed approach outperforms GPT-3 on SuperGLUE without any unlabeled data. |
CoAug: Combining Augmentation of Labels and Labelling Rules (2023.findings-acl)
Copied to clipboard
| Challenge: | Named Entity Recognition (NER) tasks require large labeled datasets to perform well. |
| Approach: | They propose a co-augmentation framework that bootstraps predictions from each model to improve few-shot models and rule-augmentation models by bootstrapping them. |
| Outcome: | The proposed model outperforms strong weak-supervision-based models by 6.5 F1 points . the proposed model can learn from limited labeled data and perform better on small datasets . |
LaSQuE: Improved Zero-Shot Classification from Explanations Through Quantifier Modeling and Curriculum Learning (2023.findings-acl)
Copied to clipboard
| Challenge: | Several recent approaches have explored training machine learning models via natural language supervision, but they fail to leverage linguistic quantifiers and mimic humans in compositionally learning complex tasks. |
| Approach: | They propose a method that can learn zero-shot classifiers from language explanations by using three new strategies: (1) modeling the semantics of linguistic quantifiers in explanations; (2) aggregating information from multiple explanations using an attention-based mechanism; (3) model training via curriculum learning. |
| Outcome: | The proposed method outperforms previous work showing an absolute gain of up to 7% in generalizing to unseen real-world classification tasks. |
