A survey on Bayesian nonparametric learning for time series analysis

N Vélez-Cruz - Frontiers in Signal Processing, 2024 - frontiersin.org
Time series analysis aims to understand underlying patterns and relationships in data to
inform decision-making. As time series data are becoming more widely available across a …

Probabilistic estimation of instantaneous frequencies of chirp signals

Z Zhao, S Särkkä, J Sjölund… - IEEE Transactions on …, 2023 - ieeexplore.ieee.org
We present a continuous-time probabilistic approach for estimating the chirp signal and its
instantaneous frequency function when the true forms of these functions are not accessible …

Markovian Gaussian Process: A Universal State-Space Representation for Stationary Temporal Gaussian Process

W Li, Y Wang, C Li, A Wu - arXiv preprint arXiv:2407.00397, 2024 - arxiv.org
Gaussian Processes (GPs) and Linear Dynamical Systems (LDSs) are essential time series
and dynamic system modeling tools. GPs can handle complex, nonlinear dynamics but are …

Stochastic filtering with moment representation

Z Zhao, J Sarmavuori - arXiv preprint arXiv:2303.13895, 2023 - arxiv.org
Stochastic filtering refers to estimating the probability distribution of the latent stochastic
process conditioned on the observed measurements in time. In this paper, we introduce a …

Hilbert Space Projection Methods for Numerical Integration and State Estimation

J Sarmavuori - 2024 - aaltodoc.aalto.fi
The aim of this thesis is to develop Hilbert space methods for approximation of integrals
appearing in filtering and smoothing of nonlinear state-space models. State-space models …

An Empirical Study of Scalable Gaussian Processes

A Sabelström - 2024 - diva-portal.org
Abstract Gaussian Processes (GPs) are a powerful Bayesian approach to regression and
classification problems in machine learning. A GP is a collection of random variables, in …
