Transformer是在2017年由谷歌提出的，当时应用在机器翻译场景。从结构上来看，它分为Encoder 和Decoder两个...
The goal of the blog post is to give anin-detailexplanation ofhowthe transformer-based encoder-decoder architecture modelssequence-to-sequenceproblems. We will focus on the mathematical model defined by the architecture and how the model can be used in inference. Along the way, we will give so...
Encoder-Decoder 注意力机制:这是 Decoder 对 Encoder 输出的注意力计算,用于将输入句子的表示结合到生成的输出句子中。此部分没有单向或双向的掩码限制,因为它可以对 Encoder 的所有输出进行注意力计算。 2. BERT 和 GPT 对 Transformer 的改造 BERT仅使用 Encoder,并增加了双向掩码(Masked Language Model, MLM)策...
BERT(Bidirectional Encoder Representation Transformers)及其变体,例如RoBERTa和DistilBERT,都属于此类架构。在该架构中为给定 token 计算的表示取决于左侧(token之前)和右侧(token之后)的上下文。所以通常称为双向注意力(bidirectional attention)。 (2)Decoder-only...

A central hypothesis is that transformers can effectively translate code between languages, acting as a bridge between programming paradigms. We develop a custom transformer encoder-decoder model for program-to-program translation that is initialized with a dataset containing C++ programs and corresponding...
In this post, we introduce the encoder decoder structure in some cases known as Sequence to Sequence (Seq2Seq) model. For a better understanding of the structure of this model, previous knowledge on…
