decoder与encoder的唯一区别就是decoder使用的是masked-self-attention即每一个词向量表示的计算仅依赖于其之前的词向量。 next token prediction 对于next token prediction训练目标,decoder-only架构(masked self attention)是必须的。发布于 2024-05-26 17:00・上海
项目主页:MeshGPT: Generating Triangle Meshes with Decoder-Only Transformers 论文地址:nihalsid.github.io/mesh-gpt/static/MeshGPT.pdf 该文章的核心贡献就是给出了一种3D结构的sequence formulation,并成功使用Decoder-only Transformer实现了auto-regressive的生成模式。 该工作总共分为两个步骤: 从大量3D meshes中...
它主要适用于理解任务,如文本分类、情感分析等。代表模型是BERT(Bidirectional Encoder Representations from Transformers),通过双向注意力机制捕捉丰富的上下文信息。 工作原理:Encoder-Only架构利用编码器对输入序列进行编码,提取其特征和语义信息。在BERT模型中,采用双向注意力机制,能够同时关注序列中的前后词语,从而获得更...
Transformers. LLMs are primarily realized as decoder-only transformers (Vaswani et al., 2017; Touvron et al., 2023a,b), incorporating an input embedding layer and multiple decoder layers. Each layer contains a self-attention network and a feedforward network with normalization modules. Crucially,...
BERT(Bidirectional Encoder Representations from Transformers):一个预训练的语言表示模型,通过双向Transformer编码器来捕捉单词的上下文信息。 Decoder-Only(仅解码器) 1. 定义与用途 Decoder-Only模型则是指那些只包含解码器部分的模型。这类模型通常用于生成输出序列,但它们不依赖于显式的编码器来生成这个序列;相反,它...

与Transformers相比,YOCO具有更好的推理效率和竞争性能。实验结果表明,在各种设置下,YOCO在大型语言模型上取得了良好的效果,即扩大训练词元数量,扩大模型大小,将上下文长度扩大到1M词元。分析结果还表明,YOCO将推理效率提高了几个数量级,特别是对于长序列建模
This paper reveals a key insight that a one-layer decoder-only Transformer is equivalent to a two-layer Recurrent Neural Network (RNN). Building on this insight, we propose ARC-Tran, a novel approach for verifying the robustness of decoder-only Transformers against arbitrary perturbation spaces. ...
