Linear Decoders: 以三层的稀疏编码神经网络而言,在sparse autoencoder中的输出层满足下面的公式: 从公式中可以看出,a3的输出值是f函数的输出,而在普通的sparse autoencoder中f函数一般为sigmoid函数,所以其输出值的范围为(0,1),所以可以知道a3的输出值范围也在0到1之间。另外我们知道,在稀疏模型中的输出层应该是...
Masked auto-encoding for feature pretraining and multi-scale hybrid convolution-transformer architectures can further unleash the potentials of ViT, leading to state-of-the-art performances on image classification, detection and semantic segmentation. In this paper, our ConvMAE framework demonstrates that...
Recent work on generative modeling of text has found that variational auto-encoders (VAE) incorporating LSTM decoders perform worse than simpler LSTM language models (Bowman et al., 2015). This negative result is so far poorly understood, but has been attributed to the propensity of LSTM decode...

linear auto-encoders 这类的预测方式可以归结为 ¯su=¯ruB,(auto)(auto)s¯u=r¯uB, 其中B∈R|I|×|I|B∈R|I|×|I| 是可学习的参数. 训练目标是 minB∑u∥¯ru−¯ruB∥22.minB∑u‖r¯u−r¯uB‖22. 作者考虑如下的情况 (¯r=~rr¯=r~): minB∥~R−~RB∥2F...
DNN's ability will increase in solving problems when more layers are used. Another advantage of DNN is the variety of layer types used, including fully connected layers, convolution layers, softmax layers, recurrent layers, and others. Autoencoder is a type of ANN that trained to reconstruct ...
