# garbage_calssify-by-resnet50-
#### 参考项目 :https://github.com/zrongcheng/huaweicloud_garbage_classify
根据该项目修改了预处理方式,并用了其中的一些小tricks:比如label smooth,random crop等。测试的地方使用了random crop,然后集成。
#### 项目描述
1. 任务是对垃圾图片进行分类,即首先识别出垃圾图片中物品的类别(比如易拉罐、果皮等),然后查询垃圾分类规则,输出该垃圾图片中物品属于可回收物、厨余垃圾、有害垃圾和其他垃圾中的哪一种。垃圾类别共40类。
2. [训练数据集下载地址](https://developer.huaweicloud.com/competition/competitions/1000007620/circumstances)
#### 准确率
1. 在官方测试集上有0.893513。
2. 我们团队也在网站上收集了每类20张左右的垃圾图片,共40类,800张。在该测试集上,模型准确率有0.86125。测试集名字是test_data。
#### 改进过程
模型名称 | 主要内容 | 训练轮次 | 得分
---|--- | --- | ---
官方baseline | Resnet50 | 50|67
model1 | 数据集进行图片增强,添加dropout |50| 77
model2 | 在model1的基础上,增加迁移学习和微调 | 3 | 71
model3 | 在model2的基础上,修改预处理方式(采用resnet50自带的) | 5 | 85
model4 | 在model3的基础上,进行图片增广,每类1000张左右 | 5 | 85
model5 | 在model4的基础上修改预处理方式(resize成( 256,256)),并将图片增强和图片遮挡写入代码 | 5 | 89
#### 总结
在该项目中,主要使用迁移学习将resnet50用于垃圾分类,迁移学习可以大大地节约训练时间,并在短时间内达到更高的准确率。这个分数是在我们团队努力一周改进后的结果,希望能对您有参考价值。该结果并不完美,还有很大的改进空间,下一步将继续对该项目进行改进,争取提高准确率。

温馨提示
人工智能(Artificial Intelligence,简称AI)是一种前沿的计算机科学技术,其核心目标是通过模拟、延伸和拓展人类智能来构建智能机器与系统。它融合了计算机科学、数学、统计学、心理学、神经科学等多个学科的知识,并利用深度学习、机器学习等算法,使计算机能够从数据中学习、理解和推断。 在实际应用中,人工智能体现在诸多领域:如机器人技术,其中机器人不仅能执行预设任务,还能通过感知环境自主决策;语言识别和语音助手技术,如Siri或小爱同学,它们能理解并回应用户的语音指令;图像识别技术,在安防监控、自动驾驶等领域实现对视觉信息的精准分析;自然语言处理技术,应用于搜索引擎、智能客服及社交媒体的情感分析等。 此外,专家系统能够在特定领域提供专业级建议,物联网中的智能设备借助AI优化资源分配与操作效率。人工智能的发展不断改变着我们的生活方式,从工作场景到日常生活,智能化正以前所未有的方式提升生产力、便捷性和生活质量,同时也在挑战伦理边界与社会规则,促使我们重新审视人与技术的关系及其长远影响。
