我正在处理以下情节:
对于我来说,我使用以下代码:
testy = [0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 1, 1, 0, 1, 1, 0, 0, 1, 1, 1, 0, 0, 1, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 1]
probs = [0. , 1. , 1. , 0. , 0. , 0.9, 0. , 0. , 0. , 0.1, 1. , 0. , 0. ,
0.9, 1. , 0. , 1. , 1. , 0. , 0. , 1. , 1. , 0. , 0. , 0.1, 1. ,
0. , 0. , 0.9, 0. , 0.9, 0. , 1. , 0. , 0. , 0. , 1. , 0. , 1. ,
0. , 0. , 0. , 0.9, 0. , 1. ]
def plot_roc_curve(testy, probs,data_dir=''):
fpr, tpr, thresholds = roc_curve(testy, probs)
fig, ax = plt.subplots()
ax.plot(fpr*100, tpr*100, color='black', marker='.')
ax.plot([0, 100], [0, 100], color='darkblue', linestyle='--')
ax.set_title('ROC Curve',fontweight='bold',loc='left')
ax.set_xlabel('False Positive Rate',fontweight='bold')
ax.set_ylabel('True Positive Rate',fontweight='bold')
plot_roc_curve(testy, probs,data_dir='')
我想修改绘图以将'%'符号添加为80%,100%...
为此,我有以下代码:
def plot_roc_curve(testy, probs,data_dir=''):
fpr, tpr, thresholds = roc_curve(testy, probs)
fig, ax = plt.subplots()
ax.plot(fpr*100, tpr*100, color='black', marker='.')
ax.plot([0, 100], [0, 100], color='darkblue', linestyle='--')
ax.set_title('ROC Curve',fontweight='bold',loc='left')
ax.set_yticklabels(['{:,.2%}'.format(x) for x in fpr])
ax.set_xticklabels(['{:,.2%}'.format(x) for x in fpr])
ax.set_xlabel('False Positive Rate',fontweight='bold')
ax.set_ylabel('True Positive Rate',fontweight='bold')
plot_roc_curve(testy, probs)
但这会破坏代码,因为标签与点不匹配:
