A Riemannian-Stein Kernel Method

open access: yesBernoulli, 2018
This paper presents a theoretical analysis of numerical integration based on interpolation with a Stein kernel. In particular, the case of integrals with respect to a posterior distribution supported on a general Riemannian manifold is considered and the

Kernel methods

open access: yes, 2023
This chapter introduces a powerful class of machine learning approaches called kernel methods, which present an alternative to arguably more widely known neural network approaches. Kernel methods can learn even highly nonlinear problems by making an implicit transformation from a low-dimensional input space into a higher-dimensional feature space. This

Synthesis of neural networks for spatio-temporal spike pattern recognition and processing

open access: yesFrontiers in Neuroscience, 2013
The advent of large scale neural computational platforms has highlighted the lack of algorithms for synthesis of neural structures to perform predefined cognitive tasks.

Convergence rates of Kernel Conjugate Gradient for random design regression [PDF]

open access: yes, 2016
We prove statistical rates of convergence for kernel-based least squares regression from i.i.d. data using a conjugate gradient algorithm, where regularization against overfitting is obtained by early stopping.

Enumeration of convex polyominoes using the ECO method [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
ECO is a method for the enumeration of classes of combinatorial objects based on recursive constructions of such classes. In the first part of this paper we present a construction for the class of convex polyominoes based on the ECO method.

Analytic Combinatorics of Lattice Paths: Enumeration and Asymptotics for the Area [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
This paper tackles the enumeration and asymptotics of the area below directed lattice paths (walks on $\mathbb{N}$ with a finite set of jumps). It is a nice surprise (obtained via the "kernel method'') that the generating functions of the moments of the ...

A novel approach to attention mechanism using kernel functions: Kerformer

open access: yesFrontiers in Neurorobotics, 2023
Artificial Intelligence (AI) is driving advancements across various fields by simulating and enhancing human intelligence. In Natural Language Processing (NLP), transformer models like the Kerformer, a linear transformer based on a kernel approach, have ...

Attributed Relational SIFT-Based Regions Graph: Concepts and Applications

open access: yesMachine Learning and Knowledge Extraction, 2020
In the real world, structured data are increasingly represented by graphs. In general, the applications concern the most varied fields, and the data need to be represented in terms of local and spatial connections.
