即双向Transformer的Encoder。整体是一个自编码语言模型（Autoencoder LM），并且其设计了两个任务来预训练...
早期RNN auto encoder结构虽然相比于传统模型取得了巨大成功,但encoder,decoder之间的信息传播仅仅时由单一的一个隐层链接完成的,这样势必会造成信息丢失,因此,Bahdanau, Dzmitry, Kyunghyun Cho, and Yoshua Bengio. “Neural machine translation by jointly learning to align and translate.” arXiv preprint arXiv:1...

AE (AutoEncoder) AE 模型作用是提取数据的核心特征(Latent Attributes),如果通过提取的低维特征可以完美复原原始数据,那么说明这个特征是可以作为原始数据非常优秀的表征。 AE 模型的结构如下图: 训练数据通过 Encoder 得到 Latent,Latent 再通过 Decoder 得到重建数据,通过重建数据和训练的数据差异来构造训练 Loss,代码...
Mask autoencoders:将输入图像切分为patch后进行随机mask掉部分patch,并重建移除像素。 # Mask Token---@tf.keras.utils.register_keras_serializable()classMaskToken(layers.Layer):"""Append a mask token to encoder output."""def__init__(self,*args,**kwargs):super(MaskToken,self).__init__(*args...
the rise of supervised learning and the increasing availability of annotated datasets have allowed DL models to leverage sample labels for more accurate cancer subtype classification. For instance, MOSAE [1] and DeepOmix [10] utilize autoencoders (AEs) to produce omics-specific representations that ...
A novel individual identification model was proposed in this paper, which concludes the autoencoder based on LSTM to obtain the meaningful latent representation from the raw recording directly, further, embedded self-attention and putted forward a combined training mode to achieve distinctive latent ...
对比了静态方法的node2vec,graphSage,graph autoencoders。在GraphPage中使用不同的聚合器进行实验,即GCN、平均池、最大池和LSTM,以报告每个数据集中性能最好的聚合器的性能。为了与GAT进行公平比较,GAT最初只对节点分类进行实验,论文在GraphSAGE中实现了一个图形注意层作为额外的聚合器,用GraphSAGE+GAT表示。本文还将...
