Parameter estimation with cluster states

Parameter estimation in differential equation models with constrained states

We introduce a method to estimate parameters and states from a differential equation model while enforcing interpretability constraints such as monotone or non-negative states. We motivate the methodology using a real data chemical engineering example and show that a variety of restrictive constraints from earlier analyses do not address the problem of interpretability. Our proposed method esti...

Cluster Spatial Localization from High-resolution Parameter Estimation

In this contribution we propose an algorithm to identify the spatial location of clusters from high resolution multi-dimensional parameter estimation results. The localization is important in both channel modelling as well as in giving a physical interpretation to the results of parameter estimation techniques, namely identifying which physical objects were involved in the propagation of the es...

Trouble for cluster parameter estimation from blind SZ surveys?

The Sunyaev-Zel’dovich (SZ) effect of galaxy clusters is a tool to measure three quantities: Compton parameter, electron temperature, and cluster peculiar velocity. However, a major problem is non-removed contamination by astrophysical sources that emit in the SZ frequencies. This includes interstellar dust emission, infra-red (IR) galaxies, and radio sources in addition to primary Cosmic Micro...
