Deep Neural Networks for Stochastic Optimization via Robust Estimation


Deep Neural Networks for Stochastic Optimization via Robust Estimation – We present a technique to classify noisy object images at low-level semantic similarity, based on the notion of unsupervised feature-level classification. We analyze the two main features of images: their spatial resolution and their intrinsic similarity. Then, we design a neural network algorithm that can efficiently and accurately predict their semantic similarity according to their spatial resolution with strong training in terms of both their geometric and spatial similarity. Such a method effectively combines both spatial resolution and visual similarity in the training data. To show their effectiveness and their superiority, we compare their performance to a deep learning based semantic image retrieval method. We show that the proposed method significantly outperforms both techniques for both classification and categorization tasks. In addition to this, we further propose a deep convolutional neural network architecture to learn the semantic cues from images. The proposed framework is able to perform semantic classification and categorization tasks effectively for both semantic and spatial information in image datasets.

We propose a method of estimating the objective function using the covariance matrix of the coefficients. The covariance matrix has many special characteristics such as the coefficient’s normality, its independence, and the coefficients’ relationship to the variable. We present a method of exploiting and refining the covariance matrix in the form of a sparse coding scheme. In particular, we derive a generalization assumption to obtain a simple algorithm to learn the covariance matrix, known as the covariance coding scheme. In this scheme, the covariance matrix is represented by a latent function whose latent variable is assumed to be a covariance matrix. The latent variable is assumed to be of a Gaussian process. The covariance matrix is then learned by a supervised learning algorithm. We provide an efficient algorithm based on a Bayesian Bayesian approach to learning the covariance matrix. The framework makes use of a model of the covariance matrix to approximate the covariance matrix. To verify our method, we present extensive experiments on synthetic and real data.
