2023.8DataWhale_cv夏令营第三期笔记_逻辑回归需要训练很多轮么-程序员宅基地
文章浏览阅读257次。使用官方提供的脑PET数据集，构建逻辑回归模型来进行脑PET图像的疾病预测，数据集被分为两类，分别为轻度认知障碍（MCI）患者的脑部影像数据和健康人（NC）的脑部影像数据，图像数据格式为nii，因此本赛题可抽象为一个二分类问题。nii是一种常用的医学图像数据格式，主要用于存储和交换神经影像数据。以下是一些主要特点：1.主要用于存储3D（三维）医学图像数据，如MRI（磁共振成像）和CT（计算机断层扫描）图像。2.支持多种数据类型，使得其可以支持不同类型的数据处理和分析。_逻辑回归需要训练很多轮么
