http://www.tuicool.com/articles/MBBbeeQ 在AlphaGo与李世石比赛期间,谷歌天才工程师Jeff Dean在Google Campus汉城校区做了一次关于智能计算机系统的大规模深度学习(Large-Scale Deep Learning for Intelligent Computer Systems)的演讲.本文是对他这次演讲的总结. 如果你无法理解信息里包含的内容,那么就会很难将其组织起来. 自从AlphaGo与李世石的比赛——这是约翰·亨利对战蒸汽锤…

CNN介绍 与之前的神经网络不同之处在于,CNN明确指定了输入就是图像,这允许我们将某些特征编码到CNN的结构中去,不仅易于实现,还能极大减少网络的参数. 一. 结构概述 与一般的神经网络不同,卷积神经网络尤其特殊之处.一般的神经网络每一层与前一层之间采用全连接:一层中的神经元之间也是互相独立的,并不共享权值:最后一层全连接层陈伟输出层,在分类任务中出表示类别得分.CIFAR-10中图像是32*32*3=3072,所以,与输入相连的第一个隐层的每个神经元的参数都有3072个,如果图像尺寸更大,那…

迁移学习两种类型: ConvNet as fixed feature extractor:利用在大数据集(如ImageNet)上预训练过的ConvNet(如AlexNet,VGGNet),移除最后几层(一般是最后分类器),将剩下的ConvNet作为应用于新数据集的固定不变的特征提取器,输出特征称为CNN codes,如果在预训练网络上是经过ReLUd,那这些codes也要经过ReLUd(important for performance):提取出所有CNN codes之后,再基于新数据集训练一个…

Competing in a data science contest without reading the data Machine learning competitions have become an extremely popular format for solving prediction and classification problems of all sorts. The most famous example is perhaps the Netflix prize.…

26 THINGS I LEARNED IN THE DEEP LEARNING SUMMER SCHOOL In the beginning of August I got the chance to attend the Deep Learning Summer School in Montreal. It consisted of 10 days of talks from some of the most well-known neural network researchers. Du…

Today I troubleshooted an Elasticsearch-cluster-down issue. Several lessons were learned: When many elasticsearch cluster nodes are restarted, to avoid HEAP spike, better to temporarily stop all connection attempts; Avoid setting allow_primary=true w…
