After calibrating the models to fit quoted prices, we analyze bid-ask spreads in terms of correlations across markets. Results are presented for a double-trigger Weather vs. Natural Gas call option.doi:10.48550/arXiv.cond-mat/0305417Rene' Carmona...

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...

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 fact, a simple cross-country analysis suggests a negative correlation between tax progressivity and informality (a powerful predictor of weak tax enforcement and high levels of tax evasion). As shown in Fig. 1, the income tax schedule is more progressive in Western economies, such as Austria...

With reference to the intact soil case (i.e., no shear band), the PGA contours of the horizontal component (Figure 5) are approximately parallel to the ground surface in the central zone of the slope, thus indicating a prevalent 1D behaviour expected due to the correlation between the ...
