英文摘要:
  We present a new method for the separation of superimposed, independent, auto-correlated components from noisy multi-channel measurement. The presented method simultaneously reconstructs and separates the components, taking all channels into account and thereby increases the effective signal-to-noise ratio considerably, allowing separations even in the high noise regime. Characteristics of the measurement instruments can be included, allowing for application in complex measurement situations. Independent posterior samples can be provided, permitting error estimates on all desired quantities. Using the concept of information field theory, the algorithm is not restricted to any dimensionality of the underlying space or discretization scheme thereof.

中文摘要:
我们提出了一种从噪声多通道测量中分离叠加、独立、自相关分量的新方法。所提出的方法同时重构和分离组件,同时考虑所有信道,从而显著提高有效信噪比,即使在高噪声区域也允许分离。可以包括测量仪器的特性,以便在复杂的测量情况下应用。可以提供独立的后验样本,允许对所有所需量进行误差估计。该算法利用信息场理论的概念,不局限于底层空间的任何维数或其离散化方案。
