PrefaceRecently on the data mining learning process, learn to naive Bayesian operation Roc Curve. It is also the experimental subject of this section, the calculation principle of ROC curve and if statistic TP, FP, TN, FN, TPR, FPR, ROC area and so on. The ROC area is often used to assess the accuracy of the model, generally think the closer to 0.5, the lower the accuracy of the model, the best state is clo

RapidMiner provides more than 500 operators for the main machine learning process, and combines a learning program with a property evaluator for the Weka learning environment. It is a standalone tool that can be used for data analysis as well as a data

referred to as the target variable variable or the dependent variable dependent variable. The attribute used to make the prediction is called the description variable explanatory variable or the independent variable of the argument. Description Task: The goal is to export patterns (correlations, trends, clusters, trajectories, and exceptions) that summarize the potential links in the data. In essence, descriptive

worth mentioning that the tool is ranked top of the data Mining tool list.In addition to data mining, RapidMiner also provides features such as data preprocessing and visualization, predictive analysis and statistical modeling, evaluation, and deployment. What's more, it al
necessary to provide a well-categorized training data set, so the cart is a supervised learning algorithm. Why use a cart?Most of the reasons for using C4.5 also apply to cart, as they are all methods of decision tree learning. The reasons for this type of explanation are also applicable to the cart. As with C4.5, they are computationally fast, the algorithms are generally popular, and the output is readable. Scikit-learn implements the CART algori

This classification of the learning phase is only my personal advice, and perhaps there are some resources in the pre-and post-classification phases that are appropriate for the current phase. I think it is very helpful to have a holistic understanding of machine learning, and I would like to hear your thoughts and tell me through the comments below! Beginner Stage Beginners
