[x] LinearSVC 13 | - [x] KernelSVC 14 | - [x] NuSVC 15 | - [x] LinearSVR 16 | - [x] KernelSVR 17 | - [x] NuSVR 18 | - [x] OneClassSVM 19 | 20 | 2021.11.05 : 加入了高斯核函数的RFF方法。 21 | 22 | 2022.01.27 : 通过向量化运算对算法进行提速,加入性能对比。 23 | 24 | 2022.01.28 : 加入缓存机制,解决大数据下Q矩阵的缓存问题,参考。 25 | 26 | 2022.01.30 : 删除Solver类,设计针对特定问题的SMO算法。 27 | 28 | 2022.02.01 : 修改SVR算法中的错误。 29 | 30 | 2022.05.27 : 重构代码,将SMO算法求解和SVM解耦,更容易解读。 31 | 32 | ## 主要算法 33 | 34 | Python(NumPy)实现SMO算法,用于求解对偶问题 35 | 36 | $$ 37 | \begin{aligned} 38 | \min_{\pmb\alpha}\quad\frac12\pmb\alpha^T\pmb Q\pmb\alpha+\pmb p^T\pmb\alpha\\ 39 | \text{s.t.}\quad \begin{aligned}\pmb y^T\pmb\alpha&=0\\ 40 | 0\leq\alpha_i&\leq C,\forall i 41 | \end{aligned} 42 | \end{aligned} 43 | $$ 44 | 45 | 和 46 | 47 | $$ 48 | \begin{aligned} 49 | \min_{\pmb\alpha}\quad\frac12\pmb\alpha^T\pmb Q\pmb\alpha+\pmb p^T\pmb\alpha\\ 50 | \text{s.t.} 51 | \begin{aligned}\quad \pmb y^T\pmb\alpha&=\delta_1\\ 52 | \pmb e^T\pmb\alpha&=\sum_{i}\alpha_i=\delta_2\\ 53 | 0\leq&\alpha_i\leq C,\forall i 54 | \end{aligned} 55 | \end{aligned} 56 | $$ 57 | 58 | 从而实现支持向量机分类、回归以及异常检测。 59 | 60 | ## Framework 61 | 62 | 我们实现了线性SVM,核SVM,用于分类,回归和异常检测: 63 | 64 | ```mermaid 65 | graph LR 66 | PySVM --> LinearSVM 67 | PySVM --> KernelSVM 68 | PySVM --> NuSVM 69 | LinearSVM --> LinearSVC 70 | LinearSVM --> LinearSVR 71 | KernelSVM --> KernelSVC 72 | KernelSVM --> KernelSVR 73 | KernelSVM --> OneClassSVM 74 | NuSVM --> NuSVC 75 | NuSVM --> NuSVR 76 | ``` 77 | 78 | 设计框架: 79 | 80 | ```mermaid 81 | graph LR 82 | cache(LRU Cache) --> Solver 83 | Solver --> LinearSVM 84 | LinearSVM --> KernelSVM 85 | Kernel --> KernelSVM 86 | RFF --> Kernel 87 | mc(sklearn.multiclass) --> LinearSVM 88 | mc --> NuSVM 89 | NuSolver --> NuSVM 90 | Kernel --> NuSVM 91 | cache --> NuSolver 92 | ``` 93 | 94 | 其中RFF表示随机傅里叶特征,LRU Cache缓存机制用于处理极大数据的场景。 95 | 96 | ## Install 97 | 98 | ```bash 99 | pip install pysvm 100 | ``` 101 | 102 | 或源码安装 103 | 104 | ```bash 105 | git clone https://github.com/Kaslanarian/PySVM 106 | cd PySVM 107 | python setup.py install 108 | ``` 109 | 110 | 运行一个简单例子 111 | 112 | ```python 113 | >>> from sklearn.datasets import load_iris 114 | >>> from pysvm import LinearSVC 115 | >>> X, y = load_iris(return_X_y=True) 116 | >>> X = (X -
