Prefixing Attention Sinks can Mitigate Activation Outliers for Large Language Model Quantization (2024.emnlp-main)
Copied to clipboard
| Challenge: | Recent advances in activation quantization methods cause outliers in tokens, causing extra overhead and speedup . a method to quantize per-tensor activation is currently challenging due to the outlier activation outlier. |
| Approach: | They propose a method to find a set of key-value cache which mitigates outliers in subsequent tokens when inserted as a prefix. |
| Outcome: | The proposed method surpasses the established baseline of per-tensor activation quantization and can be seamlessly integrated with the recent activation quantitative method. |

| Challenge: | minimizing reconstruction error is not always ideal and can overfit calibration data. |
| Approach: | They propose a method to prune large language models by divide and conquer . they propose minimizing reconstruction error by more than 90% by using calibration data . |
| Outcome: | The proposed pruning approach generates high reconstruction errors . the proposed technique reduces reconstruction error by more than 90% . |
Breaking ReLU Barrier: Generalized MoEfication for Dense Pretrained Models (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to convert pretrained dense models to MoEs are limited to ReLU-based models with natural sparsity. |
| Approach: | They propose a G-MoEfication approach for arbitrary dense models where activation sparsity assumptions no longer hold. |
| Outcome: | The proposed method reduces the inference cost associated with dense models by sparsely activating experts. |
LCIRC: A Recurrent Compression Approach for Efficient Long-form Context and Query Dependent Modeling in LLMs (2025.naacl-long)
Copied to clipboard
| Challenge: | Large language models excel in generating coherent and contextually rich outputs, but their capacity to handle long-form contexts is limited by fixed-length position embeddings. |
| Approach: | They propose a method that enables the efficient processing long-form sequences beyond the model’s length limit through recurrent compression without retraining the entire model. |
| Outcome: | The proposed method significantly improves LLM’s ability to manage extended contexts, making it well-suited for tasks that require both comprehensive context understanding and query relevance. |
