( -z((x-y))^2-1x^2z+2xyz-1y^2z+2xyz-1y^2z+y-k=-y^2z) This is the form of a hyperbola. Use this form to determine the values used to find vertices and asymptotes of the hyperbola. ( (((x-h))^2)/(a^2)-(((y-k))^2)/(b^2)=1) Match the values in this h...
在Plotly中,可以使用X、Y和Z数组来绘制三维曲面。下面是一个完整的步骤: 导入所需的库和模块: 代码语言:txt 复制 import plotly.graph_objects as go import numpy as np 创建X、Y和Z数组: 代码语言:txt 复制 # 创建X和Y的网格 x = np.linspace(-5, 5, 100) y = np.linspace(-5, 5, 100) ...
X_pred = model.predict(np.array(X_train)) X_pred = pd.DataFrame(X_pred, columns=X_train.columns) X_pred.index = X_train.index scored = pd.DataFrame(index=X_train.index) scored['Loss_mae'] = np.mean(np.abs(X_pred-X_train), axis =1) plt.figure sns.distplot(scored['Loss_mae...
