原创 nrm报错解决（ERR_INVALID_ARG_TYPE）方法

好些年不碰开发，变化很大，安装nrm的时候报错，如下：internal/validators.js:120throw new ERR_INVALID_ARG_TYPE(name, ‘string’, value);^[TypeError [ERR_INVALID_ARG_TYPE]: The “path” argument must be of type string. Received undefinedat validateString (internal/validators.js:120:

原创 tensorflow常用保存

1、tf.concat([tensor1, tensor2, tensor3,...], axis)t1 = [[1, 2, 3], [4, 5, 6]] t2 = [[7, 8, 9], [10, 11, 12]] tf.concat([t1, t2], 0) # [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]] tf.concat...

原创显著性测试，p-value/p值

p-value的意义就是当前模型要显著的好于别的模型，先计算chi-square值，然后根据值去查卡方图，得到p-value值，大于0.05（经验值），则说明拒绝假设H0的概率小，H0成立。比如硬币真假，如果7次反面，3次正面，计算chi-square的值为1.7，根据卡方图，p值介于0.25~0.1之间，大于0.05，则为真币。算法模型中，可以比较logloss，auc，如果p-value远...

转载【转】自动特征工程-隐式和显式特征交互的区别

https://blog.youkuaiyun.com/wydbyxr/article/det自动特征工程　　自动工程的三个方向，隐式特征组合（如NN，FM），半显式特征组合（如GBDT）与显式特征组合（显式特征叉乘）。隐式特征组合　　主要特点是对连续值特征非常友好，最成功的应用场景是语音和图像但是深度神经网络并不是万能的，在深度学习中，高维离散特征的变量处理非常复杂，同时缺乏可解释性，过于黑盒化...
