In this chapter the strength of electronic correlations in the normal phase of Fe-superconductors is discussed. It will be shown that the agreement between a wealth of experiments and DFT+DMFT or similar approaches supports a scenario in which strongly-correlated and weakly-correlated electrons ...

其实在和这个问题下,引申出来的一点就是,这种weak-to-strong的训练模式,会对模型的OOD test带来什么影响,比如weak labels里存在一些noise,是不是会导致strong model的OOD test变差。 Last Layer Re-Training is Sufficient for Robustness to Spurious Correlations[5]:神经网络经常会依赖spurious features进行分类,那么...

Interpretation of correlation is often based on rules of thumb in which some boundary values are given to help decide whether correlation is non-important, weak, strong or very strong. This article shows that such rules of thumb may do more harm than good, and instead of supporting interpretati...
In addition, by the ground state energy, we estimate the phase transition derived by the strong correlation effect. When the density decreases, the electronic correlation effect changes from weak to strong and we observe a sudden phase transition from paramagnetic to full spin polarization occurring ...
In this paper, we introduce a sequence of discrete Fourier transforms and define new versions of bent functions, which we shall call (weak and strong) octa/hexadeca and, in general, 2k-bent functions. We investigate relationships between these classes and completely characterize the octabent and ...
