numpy中的norm用法 np.linalg.norm()computes the norm of a NumPy array according to an order,ord, which specifies the metric by which the norm takes. For example, if we are given an array [𝑥1,...,𝑥𝑛] with numbers𝑥𝑖xi then we can compute theFrobenius Normor more commonly ...
norm.fit(generated) #用正态分布去拟合生成的数据,得到其均值和标准差。 #偏度(skewness)描述的是概率分布的偏斜(非对称)程度。偏度检验有两个返回值,其中第二个返回值为p-value,即观察到的数据集服从正态分布的概率,取值范围为0~1。 print "Skewtest", "pvalue", stats.skewtest(generated) #output #...

NumPy之:ndarray中的函数 简介 在NumPy中,多维数组除了基本的算数运算之外,还内置了一些非常有用的函数,可以加快我们的科学计算的速度。 简单函数 我们先看下比较常见的运算函数,在使用之前,我们先构造一个数组: arr = np.arange(10) array([0, 1, 2, 3
X_train = np.array([standardize(X_raw_train[row,:], X_scalers[row]) forrow in range(X_num_row)]) y_scalers = [get_scaler(y_raw_train[row,:]) for row inrange(y_num_row)] y_train = np.array([standardize(y_raw_train[row,:], y_scalers[row]) forrow in range(y_num_ro...
