The basics of Support Vector Machines and how it works are best understood with a simple example. Let’s imagine we have two tags: red and blue, and our data has two features: x and y. We want a classifier that, given a pair of (x,y) coordinates, outputs if it’s either red or...

经过替换,在SVM中一些式子的就可以如下表示。kernel trick是一个避免了在高纬度空间进行计算的方法。 更一般的kernel 称为线性核,就是普通的内积,在primal形式下也容易求解。模型选择的时候还是先从linear开始。 能不能对x做无限维的变换呢?有了kernel就能做到。
The support vector machine (SVM) and deep learning (e.g., convolutional neural networks (CNNs)) are the two most famous algorithms in small and big data, respectively. Nonetheless, smaller datasets may be very important, costly, and not easy to obtain in a short time. This paper proposes...

之前讲的hard-margin SVM,要做到把所有的点都正确分类,不允许有错误。这样的话会将noise也学进去。 我们可以退而求其次,能够允许一定程度的犯错(理解成放弃一些有可能noise的点),来增加模型的泛化能力 combination后,前半是希望w越小越好,后半是希望犯错越少越好,C用来控制两者的重要度。
we propose a new shellcode detection algorithm based on emulation and Support Vector Machine(SVM). One of the most prominent advantages is that by means of emulating, we can get the real executed path which includes key features to identify shellcode e.g. loop, xor, GetPC etc. Moreover,...
