计算机系统结构（郑伟民）习题答案，答案很全(Computer System Architecture Exercise Answers)

说明：  A commented bash script to generate our final 2nd place solution can be found in make_kaggle_solution.sh. Running all the commands sequentially will probably take 7 - 10 days on recent consumer grade hardware. If you have multiple GPUs you can speed things up by doing training and feature extraction for the two networks in parallel. However, due to the computationally heavy data augmentation it may be far less than twice as fast especially when working with 512x512 pixel input images. You can also obtain a quadratic weighted kappa score of 0.839 on the private leaderboard by just training the 4x4 kernel networks and by performing only 20 feature extraction iterations with the weights that gave you the best MSE validation scores during training. The entire ensemble only achieves a slightly higher score of 0.845.

通过列举各种实际例子，既介绍了MATLAB的一般用法，包括常用命令、语法规则、矩阵运算、数学函数及二、三维图形的绘制，又介绍了比较复杂的数值计算、图形用户界面和工具箱函数回调的编写方法。本书重点阐述了如何利用MATLAB解决化学研究中的实际问题，介绍了数值计算、绘图及优化、统计、神经网络和模糊逻辑等工具箱函数的应用；通过介绍实例和实际编写MAT—LAB程序，使读者能够熟练应用MATLAB语言实现并改进各种算法。(Through some practical examples, it introduces the general usage of MATLAB drawing, including the commonly used commands, grammar rules, matrix operations, mathematical functions, and two 3D graphics, and introduces the numerical calculation, more complex graphical user interface and the toolbox function callback writing method. This book focuses on how to use the MATLAB to solve practical problems in chemical research, introduces the application of numerical calculation, drawing and optimization, statistics, neural network and fuzzy logic toolbox function; through the introduction of practical examples and the preparation of MAT - LAB program, so that readers can skilled application of MATLAB language and improved algorithms.)

ubuntu系统性能优化简单教程 关闭最小化动画 长期使用 Ubuntu 后有一种感觉，那就是在 GNOME 中启动应用程序时，速度越来越慢。在 Ubuntu 英文论坛那边看到一个技巧，可以对这个问题起到改善作用。打开 /etc/hosts 文件，可以看到类似下面的内容： 。。。。。。。。。。。。(Ubuntu system performance optimization simple tutorial Close minimize animation After long-term use of Ubuntu, it is a kind of feeling in the GNOME started in the application, the more and more slow. In English BBS there see a Ubuntu on this problem technique that can play improved. Open/etc/hosts file, can see similar the following content: )

说明：  ARM与51编写程序的区别 测试环境：KEIL ARM的空间统一编址，单片机的空间独立编址 ARM没有bool变量，单片机可采用bit变量(ARM write programs with 51 different test environment: KEIL ARM room for a unified addressing, single-chip ARM addressing space is not an independent bool variable, the variable bit microcontroller can be used)
