Precision: Percentage of correct positive predictions relative to total positive predictions. 2. Recall: Percentage of correct positive predictions relative to total actual positives. 3. In machine learning, binary classification is a supervised learning algorithm that categorizes new observations into one of two classes. The following are a few binary classification applications, where the 0 and 1 columns are two possible classes for each observation: Application Observation 0 1; Medical Diagnosis: Patient: Healthy:

Machine Learning Classification Models. We use Classification algorithms to predict a discrete outcome (y) using independent variables (x). The dependent variable, in this case, is always a class or category. For example, predicting whether a patient is likely to develop heart disease based on their risk factors is a classification problem:Classification predictive modeling involves predicting a class label for a given observation. An imbalanced classification problem is an example of a classification problem where the distribution of examples across the known classes is biased or skewed. The distribution can vary from a slight bias to a severe imbalance where there is one …If the substance being measured is liquid water, then 12 grams of water will occupy 12 ml because the density of liquid water is 1 g/ml.
