PiPs: a Kernel-based Optimization Scheme for Analyzing Non-Stationary 1D Signals

no code implementations21 May 2018 Jieren Xu, Yitong Li, Haizhao Yang, David Dunson, Ingrid Daubechies

This paper proposes a novel kernel-based optimization scheme to handle tasks in the analysis, e. g., signal spectral estimation and single-channel source separation of 1D non-stationary oscillatory data.

Recursive Diffeomorphism-Based Regression for Shape Functions

1 code implementation12 Oct 2016 Jieren Xu, Haizhao Yang, Ingrid Daubechies

This paper proposes a recursive diffeomorphism based regression method for one-dimensional generalized mode decomposition problem that aims at extracting generalized modes $\alpha_k(t)s_k(2\pi N_k\phi_k(t))$ from their superposition $\sum_{k=1}^K \alpha_k(t)s_k(2\pi N_k\phi_k(t))$.
