SVM
SVM: 一种分类器,采用最大化分类间隔进行优化参数。
关于这个分类器两点比较重要:
1)SMO优化算法需要掌握, 可以具体参看两篇文章,John Platt的文章
以及“Improvements to Platt s SMO algorithm for SVM Classifier Design”
2)核函数的使用,如何将核函数使用到SVM中,核函数就是空间转换的函数,
说白了就是距离计算函数,如何将同类之间的距离计算的比较近,如何将低维空间转换到易于分类的高维空间。
我自己看书写的程序,采用Python实现,注释比较多(SVM: a classification, a classification intervals to maximize the use of optimization parameters.
About this classifier is more important points:
1) SMO optimization algorithms need to know, you can see the specific two articles, John Platt article
And "Improvements to Platt s SMO algorithm for SVM Classifier Design"
2) the use of nuclear function, how to use the SVM kernel function, the kernel function is a function space conversion,
That white is the distance calculation function, how relatively close distance between similar calculations, how to convert low-dimensional space to a high-dimensional space is easy classification.
I see myself writing program, using Python, notes more)

线性回归-梯度下降
拟合线性函数y=mx+b,根据偏微分求导,梯度下降就是为了得到合适的线性参数,通过求导不断更新参数,来逐渐得到最接近的参数。先将系数随便设置一个数,将x带入,根据实际y值,调整系数。损失函数就是给定系数(一般初始值为0),得到预测值,将所有预测值减去真实值,就是损失函数。如果预测的很准,损失函数最小(为0)。
