参考sampled softmax 模型中的 logQ 去偏,我们对每个logits进行了纠正,其中pjpj是每个item的估计采样概率(item j在一个随机batch内被采样到的概率)。 这里引入pjpj的作用是:降低热门商品的得分,提高冷门样本的得分。 训练用SGD: 关键的挑战是:item集合是动态的,item的频率也是动态的,因此本文最大的贡献是在一个...

论文中提到,softxmax分母中的 D 为所有可能的文档集合,这样的话候选文档集合非常大,所以论文中做了近似,训练时使用当前batch中文档这个子集来代替全集 D ,这种方法称为Sample Softmax。 TensorFlow中也有这个方法的API实现,但是我一直不是很能理解代码中到底应该怎么实现,突然这几天读到了文本匹配的开山之作 DSSM,...
labels, #标签,简单理解为正样本的id inputs, #输入,简单理解为一个batch中用户的表征$e_{i_{u_1}},...,e_{i_{u_N}}$。 num_sampled, #负样本的数量,即$I_M$ num_classes, #负样本是根据类别采样的,这里就是定义有多少类别,方便负样本从不同的类别中采样。这里每个item就是一个类别,所以这里...

Column and batch leaching experiments were performed to quantify leaching of heavy metals (Pb, Cu, Cd and Zn) from scrap dirt representing different activities at two iron scrap and metal recycling facilities. The scrap dirt is often found directly upon the bare unprotected soil at recycling facil...
Overall, the sLGE model yields statistical relationships that may be leveraged to identify the in situ growth phase of a bacterial population sampled at a regular period from a quasi-batch-culture, flow-through, steady-state ecosystem, like the human gut. To assess our model predictions, we ...
