最近做Machine Learning作业,要在Jupyter Notebook上用Keras搭建Neural Network.结果连最简单的一层神经网络都运行不了,更奇怪的是我先用iris数据集跑了一遍并没有任何问题,但是用老师给的fashion mnist一运行服务器就提示挂掉重启.更更奇怪的是同样的code在同学的电脑上跑也是一点问题都没有,让我一度以为是我的macbook年代久远配置太低什么的,差点要买新电脑了>_< 今天上课经ML老师几番调试,竟然完美解决了,不愧是CMU大神!(这里…

I am using pybrain on my Linuxmint 13 x86_64 PC. As what it is described: PyBrain is a modular Machine Learning Library for Python. Its goal is to offer flexible, easy-to-use yet still powerful algorithms for Machine Learning Tasks and a variety of p…

之前我们介绍了Recurrent neural network (RNN) 的原理: http://blog.csdn.net/matrix_space/article/details/53374040 http://blog.csdn.net/matrix_space/article/details/53376870 这里,我们构建一个简单的RNN网络,激励函数我们用sigmoid 函数,利用这个网络,我们来测试二进制数的运算.网络重复模块的表达式是: ht=σ(Wh⋅ht−1+Wi⋅Xt)…
