The most part of the experimental dependences can be presented as the sum of the temperature-independent susceptibility and the susceptibility obeying the Curie law. The both susceptibilities are described in a single manner at E 1 < 0. In some cases, the comparison of the calculated and ...
pytorch中通过 torch.nn.TripletMarginLoss 类实现，也可以直接调用 F.triplet_margin_loss 函数。 size_average 与 reduce 已经弃用。reduction有三种取值 mean , sum , none ，对应不同的返回 。 默认为 mean ，对应于一般情况下整体 的计算。该类默认使用如下距离函数， 默认为2，对应...
The sum of the first and second OR triplet cross sections agrees well with a recent approximate experimental determination of the cross section for the electron-impact dissociation of Hinto 2H. More accurate experiments are now needed to further test the OR approximation. 展开 ...
In conventional superconductors, electrons of opposite spins are bound into Cooper pairs. However, when the superconductor is in contact with a non-uniformly ordered ferromagnet, an exotic type of superconductivity can appear at the interface, with elect
In contrast, in the 3He-B phase33, L and S are combined into J 5 0; and in the 3He-A phase, L and S are decoupled and J is not well- defined32,34. There are two competing pairing possibilities in this J- triplet channel with different values of Jz: the helical polar state (...
`Learning shallow convolutional feature descriptors with triplet losses` by V. Balntas, E. Riba et al. Default: ``False``. reduction (string, optional): Specifies the reduction to apply to the output: ``'none'`` | ``'mean'`` | ``'sum'``. ``'none'``: no reduction will be appl...

When considering a large number of interacting oscillators with complex interacting network structure and random natural frequency distribution, there are rich dynamics and patterns in the processes that the coupled system 1School of Science, Beijing University of Posts and Telecommunications, Beijing ...

sum over all triplets. The two objectives would be equal as long as the standard logarithmic function is applied. However, when defining the satisfaction probabilities using a t-Gaussian distribution, the triplet embedding system substitutes the standard logarithmic function with the logtfunction to ...
