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
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, ...
In addition, LOF treats a normal point of a sparse cluster as an outlier if the sparse cluster is close to a dense cluster. This paper proposes a novel autoencoder deep learning architecture to overcome the limitations of the aforementioned techniques. In the proposed approach, we identify the...
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 ...

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 ...
This survey is inspired by the symphonic poem,Thus Spake Zarathustra.We draw an analogy between the journey of extending the context of LLM and the attempts of humans to transcend its mortality.We also try to combine this survey and the symphonic poem, and makea 36-minute video with musicto...
