In corpus linguistics, part-of-speech tagging (POS tagging or POST), also called grammatical tagging or word-category disambiguation, is the process of marking up a word in a text (corpus) as corresponding to a particular part of speech, based on bot…

背景 [作者:DeepLearningStack,阿里巴巴算法工程师,开源TensorFlow Contributor] 在分布式训练时,提高计算通信占比是提高计算加速比的有效手段,当网络通信优化到一定程度时,只有通过增加每个worker上的batch size来提升计算量,进而提高计算通信占比.然而一直以来Deep Learning模型在训练时对Batch Size的选择都是异常敏感的,通常的经验是Large Batch Size会使收敛性变差,而相对小一点的Batch Size才能收敛的更好…

Introduction To Monte Carlo Methods I’m going to keep this tutorial light on math, because the goal is just to give a general understanding. The idea of Monte Carlo methods is this—generate some random samples for some random variable of interest, th…

History of Monte Carlo Methods - Part 1 Some time ago in June 2013 I gave a lab tutorial on Monte Carlo methods at Microsoft Research. These tutorials are seminar-talk length (45 minutes) but are supposed to be light, accessible to a general computer…

Stochastic Optimization Techniques Neural networks are often trained stochastically, i.e. using a method where the objective function changes at each iteration. This stochastic variation is due to the model being trained on different data during each…

本文是对文献 <Graph Neural Networks: A Review of Methods and Applications> 的内容总结,详细内容请参照原文. 引言 大量的学习任务都要求能处理包含丰富的元素间关联关系的图数据,例如物理系统建模.疾病分类以及文本和图像等非结构数据的学习等.图形神经网络(GNNs)是一种连接模型,通过图形节点之间的消息传递捕获图形的依赖性. 图(Graph)是一种对一组对象(node)及其关系(edge)进行建模的数据结构.由于图结构的强大表示能力,近…
