So, this is a scattered diagram, every point here is a data point.and I am taking the simple case,So, I am only taking digits that are 1's or 5's,so, when you put all the 1's,and all the 5's in a scattered diagram,you realized for example, that the intensity on the 5,is...
The only random fellow in this entire operation is\nu.Now,the way you are using the inequality is to infer\mu, the sample here,from\nu.That is not the cause and effect that actually takes place.The cause and effect is that\muaffects\nu, not the other way around.But we are using it...
Approximation-Generalization tradeoff VC维分析需要选择在训练数据上接近目标函数f和在unseen data上泛化良好这两个变现之间取得平衡的假设.当在假设空间H中选择假设函数时,需要在两个矛盾的目标之间进行权衡:在假设空间中选择可以接近f的假设,同时保证训练数据上学的模型能泛化到整个输入空间上.VC维泛化边界就是一种两者...
Learning from data 今年2月的时候开始学习台大林轩田老师的机器学习课程,感觉讲的非常好,课程的参考教材是learning from data,网上查阅资料的时候发现关于这本书的笔记几乎没有,所以想自己做一个学习笔记,记录教材中的习题的解法,一来可以加深自己的理解,而来也可以给后来学习的小伙伴一些参考。这份笔记主要以learning ...

不管你在数据科学的哪一个方向研究,可能数据不平衡(imbalanced data)都是一个常见的问题。很多人总是会强调极端状况下的数据不平衡,如医疗数据,犯罪数据等。但在实际中,更多的不平衡并不会显得那么极端。如果你关注过kaggle上的比赛冠军的分享,你会发现观察数据尤其是了解不平衡情况经常会是第一步(当然还会有其他的...

The economic viability of using artificial intelligence for mammography screening remains unclear. Here, the authors evaluate the economic viability of various human-AI integration strategies using data from a mammography crowdsourcing challenge and find that a selective allocation of tasks between radiologist...
