Transformer Feed-Forward Layers Are Key-Value Memoriesarxiv.org/abs/2012.14913 1. Introduction 之前大部分研究关注的是self-attention,而FF层占据了模型的 23 的参数(对于每一层,self-attention的参数量为 4⋅d2 ,即 、、和WQ、WK、WV和WO∈Rd×d;FF层的参数量为 8⋅d2,即 ,W1∈Rd×4d,W2∈...
Recent work proposed that Feed Forward Network (FFN) in pre-trained language model can be seen as an memory that stored factual knowledge. In this work, we explore the FFN in Transformer and propose a novel knowledge fusion model, namely Kformer, which incorporates external knowledge through ...
图2 如图2所示,FFN sub-updates也就是\mathbf{v}_{i}包含的有效concepts在两个模型上均很高,作为对比,随机向量random sub-updates低了20%-30%,FFN updates即不分解为子更新,同样低了30%。 结论2:子更新可解释 图3 如图3,两个模型的所有层,由子更新得到的相关concepts占比在20%-70%之间。 4:FFN通过promo...
Each neuron will be represented by a node in the graph, and the edge weight between two nodes are their co-activation values. The co-activation value is computed by co-activation(n,m)=∑𝒙𝒉n(𝒙)𝒉m(𝒙)𝟙𝒉n(𝒙)>0,𝒉m(𝒙)>0, (6) where 𝒉n(𝒙),...
从实际的角度来看,feed-forward-only模型与视觉transformer相比有一个显著的优势,即它的复杂度相对于序列长度是线性的,而不是二次幂的。这种情况是由于应用于patches的feed-forward层的中间投影维数的大小不一定依赖于序列长度。通常中间维数被选择为输入特征数(即patches数)的倍数,在这种情况下它的模型确实是二次的,...
