Definition of Labeling Labeling: Labelling is the process of attaching a label, or name, to a particular instance of data. This can be done manually, or through automated means. Labels can be used to help identify and group data, as well as to track changes over time. How is Labeling used? Labeling is an important…
Definition of Support Vector Machines Support Vector Machines: A support vector machine (SVM) is a computer algorithm that is used to learn and predict patterns of behavior. SVM algorithms are used to create models that can be used to predict outcomes, or to classify data into discrete categories. It works by constructing a kernel matrix…
Definition of Logarithm The logarithm is a mathematical function that calculates the power to which a base number must be raised to produce a given number. It is written as log(x) and is read “log of x.” How is Logarithm used? Logarithm is a mathematical operation used to calculate the power or exponent that a…
