English(EN) On the Efficacy of Self-Supervised Point Cloud Encoders for Efficient 3D Large Language Models

自监督编码器在高效3D大语言模型方面展现出潜力

研究人员调查了低成本自监督点云编码器(特别是PCP-MAE和Point-MAE)作为3D大语言模型(3D-LLMs)昂贵的多模态编码器替代品的有效性。他们在MiniGPT-3D测试平台上的实验表明,一个端到端训练的随机初始化编码器可以实现具有竞争力的开放词汇准确率和字幕生成分数。该研究还强调了编码器架构和预训练目标之间的显著相互作用,其中PCP-MAE与MaskTransformer配对在自监督性能方面表现最佳,尽管纯粹的几何编码器在闭集分类任务上与多模态基线相比表现不佳。 AI

影响 通过评估自监督编码器,为经济高效的3D-LLM设计提供了实用指南。
