What is Logistic Regression?
Logistic regression is a supervised learning algorithm that is used to predict the probability of categorical dependent variable.
Logistic regression is a supervised learning algorithm that is used to predict the probability of categorical dependent variable.
Some of the popular use cases of the bag of words model are document similarity, text classification, feature generation, text clustering
Elastic net uses a weighted combination of the L1 and L2 penalties that are used in both LASSO and Ridge regression, respectively.
LASSO performs feature selection by shrinking the coefficients of variables to zero
If a primary interest is to conduct automatic variable selection, only LASSO can do that.
L2, or Ridge regularization, is a form of regularization in which the penalty is based on the squared magnitude of the coefficients.
L1 regularization, or LASSO (Least Absolute Shrinkage and Selection Operator), is a kind of regularization
Regularization involves adding a penalty for complexity to the model objective function to improve a model’s generalization performance.
When the vocabulary size is small, and the binary occurrence of given words are strong features
If the documents in the corpus are of varying sizes, the larger documents are more likely to have higher word counts
