A classifier is a Supervised function (machine learning tool) where the learned (target) attribute is categorical ("nominal") in order to classify. It is used after the learning process to classify new records (data) by giving them the best target attribute (prediction). Rows are classified into buckets.get price
About Classification Classification is a data mining function that assigns items in a collection to target categories or classes. The goal of classification is to accurately predict the target class for each case in the data. For example, a classification model could be used to identify loan applicants as low, medium, or high credit risks.get price
A large number of algorithms for classification can be phrased in terms of a linear function that assigns a score to each possible category k by combining the feature vector of an instance with a vector of weights, using a dot product. The predicted category is the one with the highest score. This type of score function is known as a linear predictor function and has the following general form: $${\displaystyle \operatorname {score} (\mathbf {X} _{i},k)={\boldsymbol {\beta }}_{k}\cdget price
A large number of algorithms for classification can be phrased in terms of a linear function that assigns a score to each possible category k by combining the feature vector of an instance with a vector of weights, using a dot product. The predicted category is the one with the highest score. This type of score function is known as a linear predictor function and has the following general form: $${\displaystyle \operatorname {score} (\mathbf {X} _{i},k)={\boldsymbol {\beta }}_{k}\cdot \mathbf {X} _{i},}$$where Xi is the feature vector for instance i, βk is the vector of weights corresponding to category k, and score(Xi, k) is the score associated with assigning instance i to category k. In discrete choice theory, where instances represent people and categories represent choices, the score is considered the utility associated with person i choosing category k. Algorithms with this basic setup are known as linear classifiers. What distinguishes them is the procedure for determining (training) the optimal weights/coefficients and the way that the score is interpreted. Examples of such algorithms are • Logistic regression and Multinomial logistic regression• Probit regression• The perceptron algorithm• Support vector machinesget price
A classifier identifies an instance’s class, based on a training set of data. Weka makes it very easy to build classifiers. There are many different kinds, and here we use a scheme called “J48” (regrettably a rather obscure name, whose derivation is explained at the end of the video) that produces decision trees.get price
