Spark Machine Learning Library Tutorial Binary classificationaims to divide items into two categories: positive and negative. MLlib supports two linear methods for binary classification: linear support vector machines (SVMs) and logistic regression. For both methods, MLlib supports L1 and L2 regularized variants. The training data set is represented by an RDD of LabeledPoint in MLlib. […]

Im solving a classification problem with sklearns logistic regression in python. My problem is a general/generic one. I have a dataset with two classes/result (positive/negative or 1/0), but the set is highly unbalanced. There are ~5% positives and ~95% negatives. I know there are a number of ways to deal with an unbalanced problem like […]

model. This model generalizes logistic regression to classification problems where the class labelcan take on more than two possible values. This will be useful for such problems as MNIST digit classification, where the goal is to distinguish between 10 different numerical digits. Softmax regression is a supervised learning algorithm, but we will later be using […]
