Regularized autoencoders have unique properties like robustness to missing inputs, sparse representation, and nearest value to derivatives in presentations. To use effectively, keep minimum code size and shallow encoder and decoder. They discover a high capacity of inputs and do not need any extra ...
The first approach involves the development of a Deep Stacked Sparse Wavelet Autoencoder (DSSWAE), while the second method focuses on creating a Deep Wavelet ELM Autoencoder (DW‐ELM‐AE). To enable a comprehensive comparison, experiments were conducted using different datasets, ...
The autoencoder has other variations, such as sparse autoencoder and denoising autoencoder. The autoencoder also applies backpropagation and sets the target output equal to the input. The components and process of the autoencoder are shown in Fig. 20; after the autoencoder is fully trained, ...
不完全AE限制潜在特征z的维度低于x,这可以迫使网络提取最显著的特征。也可以从其他方面进行限制:sparse autoencoder对潜在编码施加稀疏约束以获得稀疏表示 4.Reconstruction loss 一般的AE只考虑输入和输出之间的重构loss,但各层的重构loss也可以共同优化 基于AE的deep clustering优化目标为: L=\lambda L_{res} + (1...
Examples include sparse auto-encoders (SAEs) [64] and denoising auto-encoders (DAEs) and their stacked versions [65]. In an SAE model, regularization and sparsity constraints are adopted in order to enhance the solving process in the training network, while “denoising” is used as a ...

a set of TSB (target shadow background-mask) images of the first set of objects;receive, at an auto-encoder, a set of real images of the first set of objects;generate, using the auto-encoder, one or more artificial images of the target object based on the set of TSB images, wherein...
The proposed framework, called RaSeedGAN (RAndomly-SEEDed super-resolution GAN), is designed to evaluate field quantities from randomly sparse sensors without relying on full-field high-resolution training. By utilizing random sampling, the algorithm gains fragmentary perspectives of the high-resolution ...
In the context of image restoration, Suganuma et al. [15] em- ployed evolutionary search to convolutional autoencoders. Subsequently, Zhang et al. developed HiNAS [16], which utilized gradient-based search strategies and introduced a hierarchical neural archi...
The sub-band decomposition can also introduce a high degree of sparsity in the sub-bands, specifically in the non-basebands containing mostly edge information. This sparsity is introduced at the very input of the sub-band CNNs. Sparse inputs can help to reduce CNN complexity. ...
