Thank you for reaching out and for your interest in my project. I appreciate your efforts to communicate using Google Translate, and I'll do my best to help clarify your questions.
Regarding the dataset, specifically the age_level and new_user_class_level fields:
age_level: This field represents the age group of the users. Unfortunately, the dataset does not provide specific age ranges for each level, but it categorizes users into different age brackets. Typically, you might find levels like "1" for younger users and higher numbers for older age groups.
new_user_class_level: This field refers to the "city tier" or the classification of cities in China based on their economic development, population, and administrative importance. In China, cities are often categorized into tiers, with Tier 1 being the most developed cities (like Beijing, Shanghai) and higher tiers (e.g., Tier 2, Tier 3) representing smaller or less economically developed cities. This classification helps businesses tailor their strategies according to the different market environments in these cities.
I hope this explanation helps you better understand the dataset.
你好！
我是外国人，所以我用谷歌翻译来交流，如果措辞听起来很奇怪，请原谅我。
我也选择研究这个数据集，因为它很有趣，你的工作看起来做得很好，虽然我用谷歌翻译来理解它呵呵^^，但我有一些问题，因为一些变量不清楚，如果可能的话，我希望你能给我提供更多信息！
来自这里：https://tianchi.aliyun.com/dataset/56 我正在使用 user_profile 的子集，但我不明白 age_level 和 new_user_class_level 的值代表什么。特别是后者的解释是“城市级别”，我不知道这是什么意思，如果你知道，你能帮我吗？我将不胜感激！
谢谢！
