Kernelized Linear Autoencoder

Neural Processing Letters, 2021
This work proposes a new representation learning model called kernelized linear autoencoder. Instead of modeling non-linearity by the non-linear activation functions, we employ linear activations but account for non-linearity by the kernel trick. We propose four variants. The first one is the basic unsupervised kernelized linear autoencoder. The second

Dimension of Kernels of Linear Operators

American Journal of Mathematics, 1992
The basic question addressed in this paper is one of expressing the dimension of the intersection of kernels of linear operators that arise naturally in multivariate approximation theory in terms of the more easily computable dimensions of some basic blocks.

A Linear-Time Graph Kernel

2009 Ninth IEEE International Conference on Data Mining, 2009
The design of a good kernel is fundamental for knowledge discovery from graph-structured data. Existing graph kernels exploit only limited information about the graph structures but are still computationally expensive. We propose a novel graph kernel based on the structural characteristics of graphs. The key is to represent node labels as binary arrays

Linear Replicator in Kernel Space

2010
This paper presents a linear replicator [2][4] based on minimizing the reconstruction error [8][9] It can be used to study the learning behaviors of the kernel principal component analysis [10], the Hebbian algorithm for the principle component analysis (PCA) [8][9] and the iterative kernel PCA [3].

Kernel Density Estimation on a Linear Network

Scandinavian Journal of Statistics, 2016
AbstractThis paper develops a statistically principled approach to kernel density estimation on a network of lines, such as a road network. Existing heuristic techniques are reviewed, and their weaknesses are identified. The correct analogue of the Gaussian kernel is the ‘heat kernel’, the occupation density of Brownian motion on the network.

Kernel linear regression for face recognition

Neural Computing and Applications, 2013
Linear regression uses the least square algorithm to solve the solution of linear regression equation. Linear regression classification (LRC) shows good classification performance on face image data. However, when the axes of linear regression of class-specific samples have intersections, LRC could not well classify the samples that distribute around ...
