σ(e)=1/(1+exp(−e)) is the logistic function. 4.3. Counterfactual instances-based optimization We wish our NCGCF to be robust to unseen (unknown) user preference shifts to further enhance the recommendatio
hv(0)=xv where xv is the initial feature vector for the node, σ denotes the logistic sigmoid function, and ∥ denotes vector concatenation. With the network structure and node content information as inputs, the outputs of GNNs can focus on various graph analytic tasks using one of the ...

Logistic regressions use Bernoulli distribution to model the occurrence of certain events such as the specific outcome of a dice roll. Bernoulli distribution is also used as a basis to derive several other probability distributions that have applications in the engineering, aerospace, and medical indust...
用的是logistic pairwise loss: 其实化简一下,就是 -ln(1+exp(phi - phi)), 这其实就是 soft-plus function。只不过前面的方法是 softplus(正样本)-softplus(负样本), 这里是 softplus(正样本-负样本)。 phi函数的话,用的就是简单的内积函数。

In this paper we propose a novel semi-supervised method, d-graph , which does not assume any predefined structure of clusters. We follow a discriminative approach and use logistic function to directly model posterior probabilities p ( k | x ) that point x belongs to k -th cluster. Making ...
Enzymes are crucial in numerous biological processes, with the Enzyme Commission (EC) number being a commonly used method for defining enzyme function. However, current EC number prediction technologies have not fully recognized the importance of enzyme
