在"What Language Model Architecture and Pretraining Objective Work Best for Zero-Shot Generalization?"一文中,论文分别对encoder-only,encoder-decoder,decoder-only三种结构在50亿参数1700亿tokens预训练的模型上排列组合做了各种对比实验。结论如下: decoder-
Seq2Seq model个人小记 Seq2Seq模型在许多自然语言处理的任务中表现良好,比如:机器翻译,聊天机器人等。它主要由两个RNN(经常使用LSTM或者GRU)模块构成,分别充当encoder和decoder的角色,encoder有序的读取不同长度的输入,每个timestep读取一个symbol(word),encoder把不同长度的句子(inputs)转换为固定长度的向量c,decode...
This module gives you a synopsis of the encoder-decoder architecture, which is a powerful and prevalent machine learning architecture for sequence-to-sequence tasks such as machine translation, text summarization, and question answering. You learn about the main components of the encoder-decoder archit...
The encoder was modified using the lightweight MobileNetV3 feature extraction model. Subsequently, we studied the effect of the short skip connection (inverted residual bottleneck) and the NAS module on the encoder. In the proposed architecture, the skip connection connects the encoder and decoder ...

then it can model the distribution of any target vector sequence given the hidden stateccby simply multiplying all conditional probabilities. So how does the RNN-based decoder architecture modelpθdec(yi|Y0:i−1,c)pθdec(yi|Y0:i−1,c)?
The encoder-decoder model for recurrent neural networks is an architecture for sequence-to-sequence prediction problems. It is comprised of two sub-models, as its name suggests: Encoder: The encoder is responsible for stepping through the input time steps and encoding the entire sequence into a ...
如果直接从输入层往上看transformer的结构或许会比较复杂,可以先把Transformer结构的左右两边分别看成一个整体,左边的模块我们称为编码器encoder,右边称为解码器decoder。 Encoder & Decoder encoder负责处理来自输入层的序列,提取序列中的语义特征,而decoder负责生成输出。
