Evaluating a binary classification model As with regression, when training a binary classification model you hold back a random subset of data with which to validate the trained model. Let's assume we held back the following data to validate our diabetes classifier: ...

Modern machine learning theory formulates training of a classifier as minimization of an objective function which is the sum of two terms: the empirical risk which characterizes how well the classifier performs on a training data set and the regularization which controls the classifier complexity. I...
so you want to train a binary classifier that identifies those rows in the data which pertain to product quality. A colleague of yours may be interested in something completely different, perhaps categorizing product reviews based on product category (e.g., clothing, sporting ...
More specifically, we consider a binary classification problem where, in addition to positive (P) and negative (N) samples, ambiguous (A) samples are available for training a classifier. Naively, we may consider employing 3-class classification methods for the P, N, and A classes. However, ...
The generic process of training classifiers for toponym interlinking is described in Sect.3.1. Here, we discuss the training features we introduce, for better capturing and exploiting the domain knowledge of toponyms. One of the major merits of training a classifier is the combinatorial exploitation ...
For example, the Credit Card Fraud Detection dataset used in this study has 29 different features with binary output y, such as Not Fraud and Fraud. We will use this data set to make a two-class decision using a machine learning algorithm. Typical machine learning algorithms for ...
