This paper presents an audio visual (AV) person identification system using Linear Regression-based Classifier (LRC) for person identification. Class specific models are created by stacking q-dimensional speech and image vectors from the training data. The person identification task is considered a li...

可以将 logistic regression models 多个 cascading 起来,让机器自己找 feature transformation 机器找出来的情况如下: 可以把这些Logistic Regression叠在一起,某一个Logistic Regression可以是其他Logistic Regression的output。 可以给这个Model一个新名字:Neural Network (Deep learning)...
Predicting political affiliation based on a person’s income level and years of education (logistic regression or some other classifier) Predicting drug inhibition concentration at various dosages (nonlinear regression) There are all sorts of applications, but the point is this:If we have a dataset...
Logistic Regression (aka logit, MaxEnt) classifier. In the multiclass case, the training algorithm uses the one-vs-rest (OvR) scheme if the 'multi_class' option is set to 'ovr', and uses the cross-entropy loss if the 'multi_class' option is set to 'multinomial'. (Currently the 'mult...
最后,我们建一个LogisticRegression实例来训练模型。和LinearRegression类似,LogisticRegression同样实现了fit()和predict()方法。最后把结果打印出来看看: classifier =LogisticRegression() classifier.fit(X_train, y_train) predications=classifier.predict(X_test)fori, predicationinenumerate(predications[-5:]):#从...
GLRC classifier uses the test sample vector and whole train space (all the class subspaces) to calculate the global linear regression coefficient. Then GLRC computes the signed square sum of the linear regression coefficients belonging to the same class, and the result will be used for ...
