Revisiting Representation Degeneration Problem in Language Modeling (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Language modeling is a fundamental task in natural language processing, applications include machine translation, image captioning and speech recognition. |
| Approach: | They propose a cosine regularization method to solve the representation degeneration problem by analyzing the limitations of the proposed method and then propose an alternative regularization technique to tackle the problem. |
| Outcome: | The proposed method is effective in language modeling and image captioning. |
Weight Tying Biases Token Embeddings Towards the Output Space (2026.findings-acl)
Copied to clipboard
| Challenge: | Weight tying is a common practice in language model design, but its impact on learning embedding space remains unclear. |
| Approach: | They show that weight tying optimizes the embedding matrix for output prediction . they also show that tied embeddable matrices align more closely with output embedders . |
| Outcome: | The proposed weight tying approach harms performance at scale and has implications for training smaller LLMs. |
