通俗理解Xgboost 为了简化计算，XGBoost采用了一阶导数（梯度）和二阶导数（Hessian）来近似损失函数的变化，从而推导出叶子节点值的更新公式。其中 z 就是所有树的叶子节点分数之和。通过这两个正则化项，XGBoost能够在优化目标函数时，不仅考虑损失函数的最小化，还考虑了模型的复杂度，从而达到更好的泛化性能。正则化项通常包括两个部分：一个是与叶子节点数量相关的项，另一个是与叶子节点输出值大小相关的项。通过这种方式，XGBoost能够有效地计算出每个叶子节点的值，同时通过正则化项来平衡模型的复杂度和泛化能力。阅读详情

2.record of the stand-up meeting

a. Meeting content

In this meeting, we mainly discussed what we want to optimize and what functions we want to implement. In the end, we summarized some solutions to optimize and designed the general method of writing functions.

b. Meeting process

3.Progress of the development

a. Github

b. Screenshots

Web pages before UI optimization

UI optimized web page

c. Progress

So far, we have implemented most of the basic functions, such as recipes, calorie queries, random food selection, etc. We fixed some UI errors and improved the mobile ledger functionality.
