The paper presents a new technique, Layerwise Importance Sampled AdamW (LISA), for fine-tuning large language models (LLMs) that addresses the issue of high memory consumption. LISA utilizes importance sampling and freezing of middle layers during optimization, resulting in improved performance compared to existing techniques such as Low-Rank Adaptation (LoRA). Experimental results show that LISA outperforms LoRA and full parameter training in various settings, making it a promising alternative for efficient LLM fine-tuning. This technique has the potential to significantly impact academic research in the field of machine learning and natural language processing.
The paper presents the OPTIN framework, a one-shot pruning technique for transformer architectures that increases efficiency without requiring re-training. This technique leverages intermediate feature distillation to maintain competitive accuracy and improved throughput. OPTIN has shown promising results in natural language, image classification, transfer learning, and semantic segmentation tasks, making it a potential tool for efficient and wide-scale adoption of transformer architectures in academic research.
This paper presents a comprehensive evaluation dataset and strategy, Ch3Ef, for assessing the alignment of Multimodal Large Language Models (MLLMs) with human values. The dataset contains 1002 human-annotated data samples covering 12 domains and 46 tasks. The results of the evaluation provide key insights into the capabilities and limitations of MLLMs, guiding future advancements in the field and potentially creating a lasting impact in academic research.
This paper explores the potential of using large language models (LLMs) for data augmentation to mitigate high confidence errors in natural language processing (NLP) models. The study compares the effectiveness of synthetic data generated by LLMs with that of human data and finds that LLMs can significantly reduce the number of misclassifications while being more cost-effective and scalable. This technique has the potential to create a lasting impact in academic research by improving the performance of NLP models and reducing the need for human data.
This paper presents a layer-pruning strategy for pretrained LLMs that shows minimal performance degradation until a large fraction of layers are removed. The use of parameter-efficient finetuning methods suggests potential for reducing computational resources and improving memory and latency of inference. This highlights the potential for layer pruning to have a lasting impact on academic research by improving the efficiency and effectiveness of LLMs.
This paper explores the impact of model compression on the subgroup robustness of BERT language models. It investigates 18 different compression methods and settings and shows that the worst-group performance is not solely dependent on model size, but also on the compression method used. The findings suggest that model compression has the potential to improve subgroup robustness and can contribute to further research in this area.
The paper presents a mechanistic architecture design (MAD) pipeline for simplifying the resource-demanding process of developing deep learning architectures. Through a suite of synthetic tasks, the MAD pipeline identifies and tests new hybrid architectures, resulting in improved performance compared to state-of-the-art architectures. The use of MAD and synthetic tasks has the potential to significantly impact and improve the efficiency of deep learning architecture design in academic research.
The paper introduces ArabicaQA, the first large-scale dataset for machine reading comprehension and open-domain question answering in Arabic. Along with the first dense passage retrieval model trained on the Arabic Wikipedia corpus, this dataset and benchmarking of large language models offer significant advancements in the field of Arabic NLP. The publicly accessible dataset and code have the potential to create a lasting impact in academic research of these techniques.
The paper presents ChroniclingAmericaQA, a large-scale question answering dataset based on historical American newspaper pages. This dataset, containing 485K question-answer pairs, offers a unique and valuable resource for advancing QA and MRC tasks. It overcomes the limitations of previous datasets by utilizing archival document collections and providing options for testing with raw and corrected content, as well as scanned images. This has the potential to greatly impact academic research in these techniques.
TWOLAR is a two-step passage reranking method that utilizes Large Language Models (LLM) to improve document reranking. It introduces a new scoring strategy and a diverse training dataset of 20K queries and documents from four retrieval methods. The results show that TWOLAR significantly enhances the reranking ability of the underlying model, potentially creating a lasting impact in academic research on document reranking techniques.
