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…

Lessons learned from manually classifying CIFAR-10 Apr 27, 2011 CIFAR-10 Note, this post is from 2011 and slightly outdated in some places. Statistics. CIFAR-10 consists of 50,000 training images, all of them in 1 of 10 categories (displayed left). T…

What we learned in Seoul with AlphaGo March 16, 2016 Go isn’t just a game—it’s a living, breathing culture of players, analysts, fans, and legends. Over the last 10 days in Seoul, South Korea, we’ve been lucky enough to witness some of that incredibl…

翻译 | Improving Distributional Similarity with Lessons Learned from Word Embeddings 叶娜老师说:"读懂论文的最好方法是翻译它".我认为这是很好的科研训练,更加适合一个陌生领域的探索.因为论文读不懂,我总结无非是因为这个领域不熟悉.如果是自己熟悉的领域,那么读起来肯定会比较顺畅. 原文 摘要 [1] Recent trends suggest that neural-network-inspired wor…

17年的旧文,最近因为SageDB论文而重读. 文章主要思路是通过学习key的顺序.结构等来预测record在位置.存在与否等.效果方面,据称部分场景下,相对b-tree可以优化70%的内存占用. 最大价值其实在于使用ML来优化(索引)系统这个新的方向. Range Index 审视下btree查找完成的功能:输入一个key,每次选出一个可能的范围(分支节点),直到最后命中(叶子节点).这其实跟ML中模型类似. 换句话说,若能估算出数据的累积分布(记作F),那么查询key所在位置,也可以看成是…

Lessons Learned from Developing a Data Product For an assignment I was asked to develop a visual ‘data product’ that informed decisions on video game ratings taking as an indicator their ranking on the MetaCritic site. I decided to use RStudio’s Shin…

TILDE: A Temporally Invariant Learned DEtector Yannick Verdie1,∗ Kwang Moo Yi1,∗ Pascal Fua1 Vincent Lepetit2 作者基于LeNet-5 网络设计一个用于特征点检测的框架. 框架结构: 输入:图像块(image patch) 处理:神经网络-卷积,池化,全连接 输出:一个回归值 对于整张图像需要裁剪成不同小块(patch)送入网络,从而得到该图像的特征点响应值,如下图所示: 最终根据响应值来…

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…

I go to the gym and lift weights because I like the feeling of getting stronger and better. Two months ago, I started to feel a throbbing pain in my knees, yet I continued to go to the gym. I wanted so badly to keep getting stronger that I neglected…
