Leveraging Key Information Modeling to Improve Less-Data Constrained News Headline Generation via Duality Fine-Tuning (2022.aacl-main)

Copied to clipboard

Challenge: Recent language generative models are mostly trained on large-scale datasets, while in some real scenarios, the training datasets are often expensive and would be small-scale.
Approach: They propose a novel duality fine-tuning method to capture more information from limited data and build connections between tasks.
Outcome: The proposed method can capture more information from limited data, build connections between separate tasks, and is suitable for less-data constrained generation tasks.
Retentive or Forgetful? Diving into the Knowledge Memorizing Mechanism of Language Models (2024.lrec-main)

Copied to clipboard

Challenge: Pre-trained language models have shown remarkable memory formation, but vanilla networks without pre-training suffer catastrophic forgetting problem.
Approach: They conduct experiments to investigate the retentive-forgetful contradiction between vanilla and pre-trained language models by controlling the target knowledge types, learning strategies and learning schedules.
Outcome: The results show that pre-trained language models are forgetful and pre-training leads to retentive models .
