针对以上两点,该文的motivation就是能否设计一个自适应的且不需要超参数的reweighting方法,即找到一种从loss到weight的映射关系。 三 文章方法 Meta-Weighting-Net (MW-Net) 3.1 key idea 为了提出这样一个自适应的且不需要超参数的reweighting方法,文章的主要想法是用MLP来充当weight fucntion的作用,即让MLP自动学习...

一个共现网络定义为边加权的网络图 G = (V, E),其中 V (node) 代表 特征(ASV/OTU/species), E (edge)代表网络中推测的连接。E 的权重(weight)代表了连接的强度。边的符号 (+ or -) 代表推测的正的或负的关联。本文出现的网络均为无向的网络。
