潜在通道网络

Latent Channel Networks

Clifford Anderson-Bergman, Phan Nguyen, Jose Cadena Pico

摘要:

潜在欧几里得嵌入通过在欧几里得空间中表示每个节点来对给定网络进行建模,其中两个节点共享边缘的概率是节点之间距离的函数。这意味着两个节点要以高概率共享一条边,它们必须在所有维度上相对接近。该约束对于描述现代网络可能是过度限制性的,其中在至少一个区域中具有相似性可能足以具有高边缘概率。我们引入了一个新的模型,我们称之为潜在通道网络,它允许网络的这些功能。我们提出了一个EM算法来拟合模型,其中的计算复杂性是线性的边缘数和通道数,并应用该算法的合成和经典的网络数据集。

英文摘要:

Latent Euclidean embedding models a given network by representing each node in a Euclidean space, where the probability of two nodes sharing an edge is a function of the distances between the nodes. This implies that for two nodes to share an edge with high probability, they must be relatively close in all dimensions. This constraint may be overly restrictive for describing modern networks, in which having similarities in at least one area may be sufficient for having a high edge probability. We introduce a new model, which we call Latent Channel Networks, which allows for such features of a network. We present an EM algorithm for fitting the model, for which the computational complexity is linear in the number of edges and number of channels and apply the algorithm to both synthetic and classic network datasets.
