It argues that encoder-decoder architectures offer superior efficiency and performance in resource-constrained environments, especially regarding latency and throughput on edge devices. The researchers introduce a knowledge distillation framework that allows encoder-decoder models to learn from larger decoder-only models while maintaining their architectural advantages. They also demonstrate the benefits of encoder-decoder models in vision-language tasks by integrating a vision encoder. Their findings suggest that focusing on architectural choices is crucial for creating efficient SLMs, especially for on-device deployment, rather than simply scaling down large models. They show that encoder-decoder models with knowledge distillation can outperform decoder-only models and reduce latency significantly. 该论文对当前以解码器（decoder-only）架构为主的语言模型趋势提出质疑，尤其针对小型语言模型（Small Language Models, SLMs）。研究表明，在资源受限环境（如边缘设备）中，编码器-解码器（encoder-decoder）架构在延迟和吞吐量方面表现更优，具备更高的效率和性能。为此，研究者提出了一种知识蒸馏（knowledge distillation）框架，使编码器-解码器模型能够从更大的解码器模型学习，同时保持其架构优势。此外，论文还通过集成视觉编码器（vision encoder），验证了编码器-解码器模型在视觉-语言任务中的优势。研究结果表明，优化架构选择比单纯缩小大模型规模更关键，尤其是在**端侧部署（on-device deployment）**的场景中。实验进一步证明，结合知识蒸馏的编码器-解码器模型不仅优于解码器模型，还能显著降低延迟。 原文链接：https://arxiv.org/abs/2501.16273 前往小宇宙评论区与主播互动
