上午上课在稿纸上画了半天，整理下思路，下午动手写的，所有模块已大概成型，本着照顾后学者，以及资源共享的原则，贴上核心的bp算法部分，已经封装好了，使用可以直接调用。三层，基本三层就可以解决我们的这些简单的问题，输入为8×8，输出4，隐层数目conts num=8 还可进一步封装，const输入层节点，输出层节点。-Morning class in the writing paper drew a long time, under the idea of finishing the afternoon hands-on writing, and all modules have been roughly in shape, in line with care, academics, and the principle of resource sharing, the core of the bp algorithm is part of the paste has a good package, and the use of can be directly invoked. Three, the basic three layers can be resolved by these simple questions to our input for the 8 × 8, the output 4, the number of hidden layers conts num = 8　can be further packaged, const input layer nodes, output layer nodes.
