bert之类的预训练模型在NLP各项任务上取得的效果是显著的,但是因为bert的模型参数多,推断速度慢等原因,导致bert在工业界上的应用很难普及,针对预训练模型做模型压缩是促进其在工业界应用的关键,今天介绍三篇小型化bert模型——DistillBert, ALBERT, TINYBERT. 一,DistillBert 论文:DistilBERT, a distilled version of BERT: smaller, faster, cheaper and lighter GitHub
Albert是A Lite Bert的缩写,确实Albert通过词向量矩阵分解,以及transformer block的参数共享,大大降低了Bert的参数量级.在我读Albert论文之前,因为Albert和蒸馏,剪枝一起被归在模型压缩方案,导致我一直以为Albert也是为了优化Bert的推理速度,但其实Albert更多用在模型参数(内存)压缩,以及训练速度优化,在推理速度上并没有提升.如果说蒸馏任务是把Bert变矮瘦,那Albert就是把Bert变得矮胖.最近写的文本分类库里加入了Albert预

Einstein always appeared to have a clear view of the problems of physics and the determination to solve them. He had a strategy of his own and was able to visualize the main stages on the way to his goal. He regarded his major achievements as mere st
项目的挣值管理(Earned Value Management,EVM),是用与进度计划.成本预算和实际成本相联系的三个独立的变量,进行项目绩效测量的一种方法. 有三个比较重要的参数,用这三个参数能够算出成本偏差.进度偏差.成本绩效指数和进度绩效指数等. 1. 计划值 (PV,Plan Value)又叫计划工作量的预算费用(BCWS,Budgeted Cost for Work Scheduled ). 是指项目实施过程中某阶段计划要求完成的工作量所需的预算工时(或费用).也就是当前进度下的活,
