Transformer: Transformer模型的结构图如下: 大模型结构 Encoder-only Encoder-Decoder Decoder-only 最近这段时间一直在研究这个大模型的能力到底来源于哪里?对于大模型的是否智能?有像图灵奖得主Yann LeCun这样持反对意见的,也有图灵奖得主Hinton持支持意见的,作为一名从业人员,我们先从模型架构的角度来解剖大模型,看看大...
而Decoder-Only架构避免了这种复杂的跨模块参数交互，使得模型内部的参数更新和优化相对更易于管理和实现，...
T5 是 Encoder-Decoder 架构，整个网络分为两大块，且 Encoder 和 Decoder 的 Transformer Layer 参数大...
Decoder-only transformer (no encoder). Simple 1-1 tokenization is used for encoding the input. Tracks validation loss during training. Training Details: Trained for 5000 iterations on a MacBook Pro M1. Validation loss converged from 4.4 to 1.8, making it a good example of how the validation...
Apart from the various interesting features of this model, one feature that catches the attention is its decoder-only architecture. In fact, not just PaLM, some of the most popular and widely used language models are decoder-only.

YOCO采用L块堆叠,其中前L/2层为自解码器,其余模块为交叉解码器,自解码器和交叉解码器都遵循与Transformer类似的块(即,交叉注意力和FFN)。 自解码器与交叉解码器的区别在于它们各自的注意力块不同,自解码器使用高效的自注意机制(例如,滑动窗口注意力)。而交叉解码器使用全局交叉注意力来关注自解码器输出产生的共享...
Decoder-only models, such as GPT, have demonstrated superior performance in many areas compared to traditional encoder-decoder structure transformer models. Over the years, end-to-end models based on the traditional transformer structure, like MOTR, have achieved remarkable performance in multi-object ...
This work examines whether decoder-only Transformers such as LLaMA, which were originally designed for large language models (LLMs), can be adapted to the computer vision field. We first "LLaMAfy" a standard ViT step-by-step to align with LLaMA's architecture, and find that directly applying...
完整的Transformer模型包括encoder和decoder,而GPT只使用了decoder部分,且因为少了encoder,所以和原始的Transformer decoder相比,不再需要encoder-decoder attention层,对比图如下: 4. 关于Decoder-only架构的思考 GPT为什么从始至终选择Decoder-only架构?GPT-1,包括之后的2,3系列全都如此。我不知道答案,ChatGPT给出的回答...
