基本的regression算法有四种方法可以实现,分别是下面四种 LinearRegression Ridge (L2 regularization) Lasso (L1 regularization) ElasticNet (L1+L2 regularization) 这个Kaggle notebook有详细的代码, 在此向作者 juliencs 致敬! Reference: 【机器学习】正则化的线性回归 —— 岭回归与Lasso回归 还有更高级的算法可以...
That's the heart of linear regression and an algorithm really only figures out the values of the slope and intercept. It uses the values ofxandythat we already have and varies the values ofaandb. By doing that, it fits multiple lines to the data points and returns the line that is clos...

(x) can be derived through matrices to perform least square linear regression. However this beyond the scope of this tutorial, if you'd like to learn how to derive regression lines here is a good link . Also, X can be a tensor with any number of dimensions. A 1D tensor is a vector...
1. Logistic regression (logistic.py) 2. Perceptron (perceptr on.py) 3. SVM (svm.py) 4. Softmax (softmax.py) For the logistic regression classifier, multi-class prediction is difficult, as it requires a one-vs-one or one-vs-rest classifier for every class. Therefore, you only need ...

When you build a simple linear regression model, the goal is to find the parameters B0 and B1. To find the best parameters, we use gradient descent. Imagine your model finds that the best parameters are B0 = 10 and B1 = 12.
