nsfw-clip's Introduction

基于clip的一个模型分类

model可以自己任意改全连接
主要做一些数据更新的一些事情,背景是实际nsfw数据集移植到业务时,很容易存在某些类型的大量的误识别

框架

train 训练

clip_data_augment

基于新的数据集查看clip结果,通过标注新增数据(主要是看正常图片是不是被分类为黄色)
通过逐步标注训练来提高准确率
    先去小数据集,大概百万左右找出badcase(3k左右量级即可),更新数据集
    再增加数据集大小,再找出对应大小的badcase,再增加数据集训练
    最后再在一个自己的数据集上测试,可以千万级别左右的,可以下定一个准确率的结论
    这样可以快速有效的提升针对业务内容下,误识别率高的问题
    初步的话大概误识别可以从0.2%降到0.02%,让模型可用性提高
