The computational complexity of the Apriori algorithm can be influenced by the following factors which are as follows −Support Threshold − Lowering the support threshold results in higher itemsets being stated as frequent. This has an unfavorable effect on the computational complexity of the algorithm because higher candidate itemsets should ... Read More

Support counting is the procedure of deciding the frequency of appearance for each candidate itemset that survives the candidate pruning step of the apriori-gen function.One method for doing this is to compare each transaction against each candidate itemset and to refresh the support counts of candidates included in the transaction. ...

Support is a substantial measure because a rule that has very low support can appear easily by chance. A low support rule is also feasible to be tedious from a business viewpoint because it cannot be profitable to enhance items that users seldom purchase together.An association rule is an implication ...

Sampling is a broadly used method for handling the class imbalance problem. The concept of sampling is to change the distribution of examples so that the rare class is well defined in the training set. There are various techniques for sampling such as undersampling, oversampling, and a hybrid of both ... Read More

Random forest is a class of ensemble approaches particularly designed for decision tree classifiers. It integrates the predictions made by several decision trees, where each tree is created based on the values of a separate set of random vectors.The random vectors are produced from a constant probability distribution, unlike the ...

The concept is to build multiple classifiers from the initial data and then aggregate their predictions when describing unknown examples. The ensemble of classifiers can be constructed in several methods which are as follows −By manipulating the training set − In this method, multiple training sets are generated by resampling ...

A classification approach that has received considerable scrutiny is the support vector machine (SVM). This approach has its roots in statistical learning theory and has displayed promising empirical outcomes in several practical applications, from handwritten digit identification to text classification.SVM also operates with high-dimensional data and prevents the curse of ...

An artificial neural network is a system placed on the functions of biological neural networks. It is a simulation of a biological neural system. The feature of artificial neural networks is that there are several structures, which required several approaches of algorithms, but regardless of being a complex system, a ... Read More

An artificial neural network has a more complicated mechanism than that of a perceptron model. There are several methods in multilayer artificial neural networks which are as follows −The network can include multiple intermediary layers between its input and output layers. Such intermediary layers are known as hidden layers and ... Read More
