Superfluorescence spectra of excitons in quantum wells
P. Grünwald, G. K. G. Burau, H. Stolz +1
We study the fluorescence light emitted from GaAs excitons in semiconductor quantum wells. The excitons are modeled as interacting bosons. By combining quantum optical methods for…
Optimal Squeezing in the Resonance Fluorescence of Single Photon Emitters
P. Grünwald, W. Vogel
Annual Review of Astronomy and Astrophysics, Volume 51, page 511e studied for coherently driven single photon sources, such as atoms and quantum dots. Maximal squeezing is realized…
Horizon-Independent Optimal Prediction with Log-Loss in Exponential Families
Peter Bartlett, Peter Grunwald, Peter Harremoes +2
We study online learning under logarithmic loss with regular parametric models. Hedayati and Bartlett (2012b) showed that a Bayesian prediction strategy with Jeffreys prior and seq…
Follow the Leader If You Can, Hedge If You Must
Steven de Rooij, Tim van Erven, Peter D. Grünwald +1
Follow-the-Leader (FTL) is an intuitive sequential prediction strategy that guarantees constant regret in the stochastic setting, but has terrible performance for worst-case data.…
Maximum Entropy and the Glasses You Are Looking Through
Peter D. Grunwald
We give an interpretation of the Maximum Entropy (MaxEnt) Principle in game-theoretic terms. Based on this interpretation, we make a formal distinction between different ways of {e…
