I. Concepts Association Rule Mining: discovering interesting and frequent patterns, associations, and correlations between item sets of a large amount of data, such as the food database and relational database. Measurement of the degree of interest of association rules:Support,Confidence K-item set: a set of K items Frequency of the item set: number of transactions that contain the item set Frequent Item Se

transaction by user shell+ip+ hostname according to different user's login (all three are the same user) Based on this, the basic principle of mining 2 algorithm for user input command sequence frequent pattern is realized. The fp-growth algorithm mainly solves the collection of frequent items where the number of occurrences reaches a certain threshold in multiple sets. A FP tree is a compressed representation of input

In today's big data era, data is money. With the transition to an application-based domain, data shows exponential growth. However, 80% of the data is unstructured, so it requires a program and method to extract useful information and convert it into an understandable and available structured form. A large number

. Pruning, satisfying the support and credibility of these 1-itemsets move to the next round of processes, and then look for the 2-itemsets that appear. Repeat, the itemsets for each level are repeated, knowing the size of the itemsets we defined earlier. is the algorithm supervised or unsupervised? Apriori is generally considered an unsupervised method of learning, as it is often used to excavate and discover interesting patterns and relationships.But, wait, there is ... The Aprior

only 1. So the count of conditional pattern bases is determined by the minimum count of nodes in the path.Depending on the conditional pattern base, we can get the conditional FP tree for that commodity, for example i5:According to the conditions of the FP tree, we can do a full array of combinations, to get the frequent patterns excavated (here to the commodity itself, such as i5 also counted in, each commodity mining out of the frequent pattern mus

and visualize data. Through various examples, the reader can learn the core algorithm of machine learning, and can apply it to some strategic tasks, such as classification, prediction, recommendation. In addition, they can be used to implement some of the more advanced features, such as summarization and simplification.I've seen a part of this book before, but the internship involves working with the data

First talk about the problem, do not know that everyone has such experience, anyway, I often met.Example 1, some websites send e-mails to me every few days, each e-mail content is something I do not interest at all, I am not very disturbed, to its abhorrence.Example 2, add a feature of a MSN robot, a few times a day suddenly pop out a window, recommend a bunch of things I don't want to know, annoying ah, I had to stop you.Every audience just want to see what he is interested in, rather than some

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
