About this Course This course will teach you the "magic" of getting deep learning to work well. Rather than the deep learning process being a black box, you will understand what drives performance, and be able to more systematically get good res…
While it's great to use the RxJS built-in operators, it's also important to realize you now have the knowledge to write them by yourself if needed. The mapoperator turns out to be a simple MapSubscriber which takes a function and applies it to the va…
Author: Emmanuel Goossaert 翻译 This article is a short guide to implementing an algorithm from a scientific paper. I have implemented many complex algorithms from books and scientific publications, and this article sums up what I have learned while se…

对抗网络是14年Goodfellow Ian在论文Generative Adversarial Nets中提出来的. 原理方面,对抗网络可以简单归纳为一个生成器(generator)和一个判断器(discriminator)之间博弈的过程.整个网络训练的过程中, 两个模块的分工 判断网络,直观来看就是一个简单的神经网络结构,输入就是一副图像,输出就是一个概率值,用于判断真假使用(概率值大于0.5那就是真,小于0.5那就是假) 生成网络,同样也可以看成是一个神经网络模型,输入是一组随机数Z,输出是…
A Complete Tutorial to Learn Data Science with Python from Scratch Introduction It happened few years back. After working on SAS for more than 5 years, I decided to move out of my comfort zone. Being a data scientist, my hunt for other useful tools w…

XAF ships with the Business Class Library that contains a number of persistent classes ready for use in your applications. All these classes derive from the BaseObject base persistent class declared in the same library. This is a recommended-to-use f…
In this lesson, you will learn how to implement business classes from scratch. For this purpose, the Position business class will be implemented. This class will be used in the Contact class, implemented previously. You will also learn the basics of…

Improving Supervised Seq-to-seq Model 有监督的 seq2seq ,比如机器翻译.聊天机器人.语音辨识之类的 . 而 generator 其实就是典型的 seq2seq model ,可以把 GAN 应用到这个任务中. RL(human feedback) 训练目标是,最大化 expected reward.很大的不同是,并没有事先给定的 label,而是人类来判断,生成的 x 好还是不好.   简单介绍一下 policy gradient.更新 encode…
目录 Prepare 在上篇博客(AN网络之入门教程(四)之基于DCGAN动漫头像生成)中,介绍了基于DCGAN的动漫头像生成,时隔几月,序属三秋,在这篇博客中,将介绍如何使用条件GAN网络(conditional GAN)生成符合需求的图片. 做成的效果图如下所示,"一键起飞". 项目地址:Github 在阅读这篇博客之前,首先得先对GAN和DCGAN有一部分的了解,如果对GAN不是很了解的话,建议先去了解GAN网络,或者也可以参考一下我之前的博客系列. 相比较于普通的GAN网络,c…

Implement a trie with insert, search, and startsWith methods. Note:You may assume that all inputs are consist of lowercase letters a-z. 这道题让我们实现一个重要但又有些复杂的数据结构-字典树, 又称前缀树或单词查找树,详细介绍可以参见网友董的博客,例如,一个保存了8个键的trie结构,"A", "to", "tea&quo…

八. 构建LFS系统 1. 准备虚拟内核文件系统 内核会挂载几个文件系统用于自己和用户空间程序交换信息.这些文件系统是虚拟的,并不占用实际磁盘空间, 它们的内容会放在内存里. mkdir -pv $LFS/{dev,proc,sys,run} mknod -m 600 $LFS/dev/console c 5 1 mknod -m 666 $LFS/dev/null c 1 3 mount -v --bind /dev $LFS/dev mount -vt devpts devpts $LFS/…
一. 准备工作 1. 需要一个Linux宿主系统,例如早先版本的 LFS,Ubuntu/Fedora,SuSE 或者是在你的架构上可以运行的其它发行版 如果想实现Win7与Linux双系统,可参考我的上一篇博文:Win7下硬盘安装Ubuntu 12.04.3双系统 2. 参考网址:Linux From Scratch Version 7.7-systemd (简体中文版) 3. 参考文档:LFS-BOOK-7.7-systemd.pdf 4. 参考命令:lfs-7.4-command.txt 二…
