Since sequential information plays an important role in modeling user behaviors, various sequential recom- mendation methods have been proposed. Methods based on Markov assumption are widely-used, but independently com- bine several most recent components. Recently, Recurrent Neural Networks (RNN) based methods have been successfully applied in several sequential modeling tasks. However, for real- world applications, these methods have difficulty in modeling the contextual information, which has been proved to be very important for behavior modeling. In this paper, we propose a novel model, named Context-Aware Recurrent Neural Net- works (CA-RNN). Instead of using the constant input matrix and transition matrix in conventional RNN models, CA-RNN employs adaptive context-specific input matrices and adap- tive context-specific transition matrices. The adaptive context- specific input matrices capture external situations where user behaviors happen, such as time, location, weather and so on. And the adaptive context-specific transition matrices capture how lengths of time intervals between adjacent behaviors in historical sequences affect the transition of global sequential features. Experimental results show that the proposed CA- RNN model yields significant improvements over state-of-the- art sequential recommendation methods and context-aware recommendation methods on two public datasets, i.e., the Taobao dataset and the Movielens-1M dataset.

吐血推荐C++开源框架，增加对C++的熟悉程度 cJSON是C语言中的一个JSON编解码器，非常轻量级，C文件只有500多行，速度也非常理想。UNIX V6 的内核源代码包括设备驱动程序在内 约有1 万行，这个数量的源代码，初学者是能够充分理解的。 libevent ：事件通知库

linux命令是对Linux系统进行管理的命令。对于Linux系统来说，无论是中央处理器、内存、磁盘驱动器、键盘、鼠标，还是用户等都是文件，Linux系统管理的命令是它正常运行的核心，与之前的DOS命令类似。linux命令在系统中有两种类型：内置Shell命令和Linux命令。

Hibernate+Servlet+Bootstrap 简易论坛系统前端写的比较多，用的原生的html+css+js，用到了bootstrap、jquery、ajax，实现了较多的一些小功能，后端只是使用了hibernate和原生的servlet!

图论知识的综合讲解，很适合初学者，对于ACM和ICPC的人也还好，比较基础的东西，毕竟基础很重要，基础不牢，地动山摇
