Zero-shot learning (ZSL), which focuses on transferring the knowledge from the seen classes to unseen ones, has attracted more and more attention in the computer vision community. Exploring the relationships among the spaces of visual representation, semantic description and label information is a key to the success of ZSL. In this paper, we propose a novel approach by using a two-layer stacked autoencoder (StAE) with manifold regularizations to construct the tight relations of different spaces, where the first-layer encoder aims to project a visual feature vector into the semantic space, and the second-layer encoder connects the semantic description of a sample with its label directly. Meanwhile, the decoders seek to reconstruct the visual representation from label information and semantic description successively. Besides, two manifold regularizers are integrated in the stacked autoencoder, which captures the manifold structures residing in the different spaces effectively. Compared with the previous related works, the proposed approach is a more general framework and has stronger transfer ability from seen classes to unseen classes. Extensive experiments on the benchmark datasets clearly demonstrate that our StAE performs significantly better than the state-of-the-arts.

stacked autoencoders enjoy their popularization with the prosperity of deep learning in recent years. However, relative studies seldom exploit the intrinsic information buried in the interrelations between the samples with respect to deep networks. Regarding this, the manifold regularization is introduced to analyze the neighborhood of each training sample, which leads to a manifold regularized stacked autoencoder hierarchical framework with deep multilayer substructures. A series of experiments are conducted upon MNIST and YaleFaces using locally linear embedding as the manifold regularization module. The results show that neighborhood analysis should be combined with stacked autoencoders to achieve some notable promotions of their performances.

The study of climatic variables that govern the Indian summer monsoon has been widely explored. In this work, we use a non-linear deep learning-based feature reduction scheme for the discovery of skilful predictors for monsoon rainfall with climatic variables from various regions of the globe. We use a stacked autoencoder network along with two advanced machine learning techniques to forecast the Indian summer monsoon. We show that the predictors such as the sea surface temperature and zonal wind can predict the Indian summer monsoon one month ahead, whereas the sea level pressure can predict ten months before the season. Further, we also show that the predictors derived from a combination of climatic variables can outperform the predictors derived from an individual variable. The stacked autoencoder model with combined predictors of sea surface temperature and sea level pressure can predict the monsoon (June-September) two months ahead with a 2.8% error. The accuracy of the identified predictors is found to be superior to the state-of-the-art predictions of the Indian monsoon.

Unsupervised feature learning with deep networks has been widely studied in the recent years. Despite the progress, most existing models would be fragile to non-Gaussian noises and outliers due to the criterion of mean square error (MSE). In this paper, we propose a robust stacked autoencoder (R-SAE) based on maximum correntropy criterion (MCC) to deal with the data containing non-Gaussian noises and outliers. By replacing MSE with MCC, the anti-noise ability of stacked autoencoder is improved. The proposed method is evaluated using the MNIST benchmark dataset. Experimental results show that, compared with the ordinary stacked autoencoder, the R-SAE improves classification accuracy by 14% and reduces the reconstruction error by 39%, which demonstrates that R-SAE is capable of learning robust features on noisy data.

In this paper, we proposed a stacked autoencoder (SAE)-based approach to ultra wide band (UWB) radar for sense-through-foliage target detection. As one of the widely used deep learning structures, SAE could learn representations of data with multiple levels of abstraction automatically. Processing the poor signal collections, in some positions, the SAE-based target detection approach performed well. While in other positions, a single radar target detection performed under satisfaction, RAKE structure was applied in radar sensor networks with maximum ratio combing and equal combine to integrate radar echoes from different radar cluster-members. The experimental results showed that the RAKE-SAE-based method could qualify the mission of target detection.

Network traffic classification is an important task in modern communications. Several approaches have been proposed to improve the performance of differentiating among applications. However, most of them are based on supervised learning where only labeled data are used. In reality, a lot of datasets are partially labeled due to many reasons and unlabeled portions of the data, which can also provide informative characteristics, are ignored. To handle this issue, we propose a semi-supervised approach based on deep learning. We deployed deep learning because of its unique nature for solving problems, and its ability to take into account both labeled and unlabeled data. Moreover, it can also integrate feature extraction and classification into a single model. To achieve these goals, we propose an approach using stacked sparse autoencoder (SSAE) accompanied by denoising and dropout techniques to improve the robustness of extracted features and prevent the over-fitting problem during the training process. The obtained results demonstrate a better performance than traditional models while keeping the whole procedure automated.

With the development of rapid technology, the similarity between plants is increasing, which will enhance the classified workload of botanists. Therefore, it is urge to find a quick automatic classification method. In recent years, the performance of autoencoder has become more and more prominent. Consequently, in this paper, we employ stacked autoencoder to classify three plants, including 630 images in total. The result of this experience shows that the accuracy of classification is 93.3%.

Sparse representation classification (SRC) is a new framework for classification and has been successfully applied to face recognition. However, in some cases it is not well to represent the test sample accurately, which tends to undermine the classification accuracy. In order to alleviate this issue, a deep sparse representation based classification (DSRC) method with a deep dictionary which learned by stacked autoencoder is proposed. Specifically, the proposed method trains a stacked autoencoders by pseudoinverse learning and used the hidden outputs to construct a deep dictionary. Given the deep dictionary, a hierarchical sparse representation based classification method is presented to determine the label for each test sample by a weighted residuals strategy. The experimental results show that the proposed method can achieve a comprehensively better performance compared with the state-of-the-art classification methods.

Indian summer monsoon has distinct behaviors in its early and late phase. The influencing climatic factors are also different. In this work we aim to predict the national rainfall in these phases. The predictors used by the forecast models are discovered using a stacked autoencoder deep neural network. A fitted regression tree is used as the forecast model. A superior accuracy to state of art method is achieved. We also observe that the late monsoon can be predicted with higher accuracy than early monsoon rainfall.

Many studies have shown that deep learning outperforms traditional machine learning methods in many applications. To prevent overfitting, a huge number of training samples is usually required in training process of deep learning. However, collecting such a large dataset is time-consumed and costly. Recently, several methods have been proposed to effectively learn the models with a limited number of training samples. In this paper, we experimentally evaluate the data augmentation and the transfer learning methods on the MNIST dataset with stacked autoencoders. The experiment results suggest that the transfer learning method can improve the performance of the SAE when training samples are insufficient.
