This illustrates the `datasets.make_multilabel_classification` dataset generator. Each sample consists of counts of two features (up to 50 in total), which are differently distributed in each of two classes.Points are labeled as follows, where Y means the class is present: 【数据集生成器“data...

multi-label-classification 基于tf.keras,实现多标签分类CNN模型。 如何使用 快速上手 run.py同目录下新建logs文件夹,存放日志文件;训练完毕会出现models文件夹,存放模型; 查看configs.py并进行修改,此为参数配置文件; 实际用自己的数据训练时,可能需要执行以下utils/check_label_file.py,确保标签文件中的图片真实可用...
