如何将数据帧的字符串值映射到某个数字以绘制集群？
how to map string value of dataframe to some number to plot Cluster?
我想通过我知道的唯一方法绘制我的数据集的集群是将字符串映射到某个整数值。喜欢
data_mapped=data.copy()
data_mapped['Language']=data_mapped['Language'].map({'English':0,'French':1,'German':2})
data_mapped
但是在这个例子中，我只有 3 个唯一的语言值可以通过这种方法映射
现在我不知道如何将多个唯一字符串值转换为整数值并绘制簇？
我想按某些列进行聚类，例如 (Color,fabric,dress_type)
我想对整个数据进行聚类？
现在我的数据集是：
file_list=glob.glob('json_file/[!Merg_all]*json')
merg_all_list=[]
for file in file_list:
print(file)
raw_data=pd.read_json(str(file))
raw_data.head()
for i in raw_data['product']:
merg_all_list.append(i)

为您的数据选择合适的可视化技术。
对于分类数据，条形图比散点图更合适，因为您不需要 x 轴是数字。
还要选择合适的算法... K-means 仅对 连续 变量有意义。将类别编码为 k-means 的整数只是 错误 。在您的情况下，k-means 会假设英语和德语的平均值正好是法语。
