处理数据不平衡问题

• 预处理excel文件中的数据不平衡问题

data = pd.read_excel ("file)
list_label = []
train_list, dev_list, test_list = [],[],[]
data_value = data.value
for i in range(len(data_value)):
    if data_value[i][0] not in list_label:
        list_label.append(data_value[i][0])
for j in range(len(list_label)):
    s = data.loc[data["标签"] == list_label[j]]
　　 s = s.loc[:,['a','c']]            #选取'a','c'两列
    s = s.ix[:].value
    s = s.tolist()
    "接下来就是对自己训练、测试、验证进行取值了"
