SPECTRAL-SPATIAL CLASSIFICATION OF HYPERSPECTRAL REMOTE SENSING IMAGES USING VARIATIONAL AUTOENCODER AND CONVOLUTION NEURAL NETWORK
Hyperspectral classification feature extraction spectral channels deep learning
2019/2/28
In this paper, we propose a spectral-spatial feature extraction framework based on deep learning (DL) for hyperspectral image (HSI) classification. In this framework, the variational autoencoder (VAE)...
Error Estimation of Practical Convolution Discrete Gaussian Sampling
Discrete Gaussian Sampling convolution theorem lattice
2018/4/4
Discrete Gaussian Sampling is a fundamental tool in lattice cryptography which has been used in digital signatures, identify-based encryption, attribute-based encryption, zero-knowledge proof and full...
ETALON IMAGES: UNDERSTANDING THE CONVOLUTION NEURAL NETWORKS
CNN deep learning manifold learning affine transformations graphs etalons
2018/6/4
In this paper we propose a new technic called etalons, which allows us to interpret the way how convolution network makes its predictions. This mechanism is very similar to voting among different expe...
Optimizing polynomial convolution for NTRUEncrypt
Quantum-safe cryptography NTRUEncrypt security estimation
2018/3/5
NTRUEncrypt is one of the most promising candidates for quantum-safe cryptography. In this paper, we focus on the NTRU743 paramter set. We give a report on all known attacks against this parameter set...

FEATURE DESCRIPTOR BY CONVOLUTION AND POOLING AUTOENCODERS
Image Matching Representation Learning Autoencoder Pooling Learning Descriptor Descriptor Evaluation
2015/4/1
In this paper we present several descriptors for feature-based matching based on autoencoders, and we evaluate the performance of these descriptors. In a training phase, we learn autoencoders from ima...

2013/4/27
In a recent paper Birke and Bissantz (2008) considered the problem of nonparametric estimation in inverse regression models with convolution-type operators. For multivariate predictors nonparametric m...
An extension of solutions to convolution equations with the loss of smoothness
Homogeneous convolution equations mean periodic functions zeros of entire functions
2012/6/19
In the present paper the smoothness loss of an extension of solutions to convolution equations is studied. Also examples for some kinds of convolvers are given.
Identifying High-Impact Sub-Structures for Convolution Kernels in Document-level Sentiment Classification
High-Impact Sub-Structures Convolution Kernels Document-level Sentiment Classification
2013/4/22
Convolution kernels support the modeling of complex syntactic information in machine-learning tasks. However, such models are highly sensitive to the type and size of syntac-tic structure used. It is ...
Exact Parameterized Multilinear Monomial Counting via k-Layer Subset Convolution and k-Disjoint Sum
Parameterized MultilinearConvolution
2012/12/3
We present new algorithms for exact multilinear k-monomial counting which is to compute the sum of coefficients of all degree-k multilinear monomials in a given polynomial P over a ring R described by...
Multiplicative noise, fast convolution, and pricing
Computational Finance Stochastic Processes Non-Gaussian Option Pricing Numerical Methods for Option Pricing
2011/7/19
In this work we detail the application of a fast convolution algorithm computing high dimensional integrals to the context of multiplicative noise stochastic processes. The algorithm provides a numeri...
Abstract: In a convolution semigroup over a locally compact group, measurability of the translation by a fixed element implies continuity. In other words, the measurable centre coincides with the topo...

2011/9/9
Abstract: We consider the framework of an operator-valued noncommutative probability space over a unital C*-algebra B. We show how for a B-valued distribution \mu one can define convolution powers wit...

2011/9/1
Abstract: Given a locally compact quantum group $\G$, we study the question of when completely bounded homomorphisms $\pi:L^1(\mathbb G)\rightarrow\mathcal B(H)$ are similar to *-homomorphisms. By ana...
