其实,可以将这种方式看作是一个lookup table:对于每个 word,进行 word embedding 就相当于一个lookup操作,在表中查出一个对应结果。 在Pytorch 框架下,可以使用torch.nn.Embedding来实现 word embedding: classEmbeddings(nn.Module):def__init__(self,d_model,vocab):super(Embeddings,self).__init__()self.lut...
嵌入层(embeddings layer)是 Transformer 架构的第一部分,创建嵌入层就像编写以下代码一样简单: *备注——请不要将此段代码及其约定视为好的编码风格,写这段代码的目的是为了便于理解。 代码Code import torch.nn as nn vocabulary_size = 2 num_dimensions_per_word = 2 embds = nn.Embedding(vocabulary_size,...

In contrast to traditional transformer blocks using a set of pre-defined parameters as positional embeddings, we propose the input-aware positional embedding (IPE) which is dynamically generated according to the input feature. We implement this idea by designing the IPE transformer, which enjoys ...
A device includes one or more processors configured to process first input time-series data associated with a first time range using an embedding generator to generate an input embedding. The input embedding includes a positional embedding and a temporal embedding. The positional embedding indicates a...
