前言 问题:尽管Encoder-Decoder结构听起来更复杂,能做更多的事情,但许多流行的模型(如 GPT)都只使用Decoder-Only结构,这样是否更好呢? 1、Decoder-Only 模型 Decoder和Encoder结构之间有什么区别?关键区别在于输入注意力是否(因果)被掩码mask掉。Decoder结构使用的是基于掩码mask的注意力。 设想我们有一个输入句子,
在深度学习和自然语言处理(NLP)领域,模型架构可以大致分为三种类型:Encoder-only、Decoder-only 和 Encoder-Decoder。这些架构各有其特点、优势和应用场景。以下是对这三种模型的比较和当前的趋势分析: 1. En…
decoder-only有个值得说的特点是推理可以使用KV-cache技术,原因是casual attention mask可以让历史不可改变,只需要把past的attention矩阵存下来,新来token只需要计算新的一行,列直接填充-inf即可。(当然这个也带了灾难性的低计算访存比,增加了部署加速难度) decoder-only attention mask GPT从3.5开始才真正的大放异彩,...

Encoder也會在數據區塊結尾保留尾端的字元,並在下一個編碼作業中使用尾端字元。 例如,數據區塊的結尾可能是不相符的高 Surrogate,而相符的低 Surrogate 可能位於下一個數據區塊中。 因此,GetDecoder和GetEncoder對於網路傳輸和檔案作業很有用,因為這些作業通常會處理數據區塊,而不是完整的數據流。

It is shown that treating encoders as a between-subjects factor and decoders as a within-subjects factor can yield tests of significance that differ markedly from those obtained from analyses regarding decoders as a between-subjects factor and encoders as a within-subjects factor. Although these...
Besides, adding left- right flipped inputs doubles the computation complexity with only marginal performance improvement. Adding Decoder: The second row block in Table 3 contains the results when adopting the proposed decoder structure. The performance is improved from 77.21% to 78.85% or 78.51% to...
