Inference with minimal Gibbs free energy in information field theory
Non-linear and non-gaussian signal inference problems are difficult to tackle. Renormalization techniques permit us to construct good estimators for the posterior signal mean within information field theory (IFT), but the approximations and assumptions made are not very obvious. Here we introduce the simple concept of minimal Gibbs free energy to IFT, and show that previous renormalization resu...
متن کاملComment on "Inference with minimal Gibbs free energy in information field theory".
Enßlin and Weig [Phys. Rev. E 82, 051112 (2010)] have introduced a "minimum Gibbs free energy" (MGFE) approach for estimation of the mean signal and signal uncertainty in Bayesian inference problems: it aims to combine the maximum a posteriori (MAP) and maximum entropy (ME) principles. We point out, however, that there are some important questions to be clarified before the new approach can be ...
متن کاملComment on "Minimal energy cost for thermodynamic information processing: measurement and information erasure".
The fundamental lower bounds on the thermodynamic energy cost of measurement and information erasure are determined. The lower bound on the erasure validates Landauer's principle for a symmetric memory; for other cases, the bound indicates the breakdown of the principle. Our results constitute the second law of "information thermodynamics," in which information content and thermodynamic variabl...
متن کاملGradient field microscopy of unstained specimens: reply to comment.
We reply to the comment written by Ferrari and Ayubi on our recent paper, Kim et al. [Opt. Express, 20, 6737 (2012)]. We maintain that our use of Fourier filtering methods lead to valuable intrinsic contrast live cell imaging. Judging by their comments regarding the limit sin(x)~x, it seems that the authors overlooked Fig. 2 in our paper, where we show results with sinusoidal masks of different...
