self-attention is widely applied in language inference tasks. Motivated by these observations, we propose a self-attention traffic matrix prediction (SATMP) model for long-term network TM prediction in IIoT scenarios. SATMP consists of three components: (a) a spatial–temporal encoding for obtaini...
一.概览: 大体上仍然是emb+mlp之类的架构,在一些细节上有所不同. 1.embed部分 常规的处理下,multHotFea用pooling扔进去 2.主体架构部分 类似DIN的思想,与target做attention,attention使用的是mlp作为小分类器 二.个人认为比较有趣的地方 时间:history click seq&unclick seq-->pctr 空间:item pos:pos1->click...
