predictable, the algorithm generates a separate decision tree for each predictable column.The principle of the algorithm:The Microsoft decision tree algorithm generates a data mining model by creating a series of splits in the tree. These splits are represented as "nodes". Whenever an input column is found to be closely related to a predictable column, the algorithm adds a node to the model. The algorithm

Spatial Data Mining refers to the process of extracting hidden knowledge and spatial relationships from spatial databases and discovering useful Theories, Methods, and technologies of features and patterns. The process of spatial data mining and knowledge discovery can be roughly divided into the following steps:Data p

business predictive analytics. According to a poll by Kdnuggets in 2013, the software is more notch above than the R language in terms of utilization. Because of its GUI features, it is suitable for beginners in data mining.This course chapters around the actual mining and analysis of business needs, mining work commonly use
category or establish an analysis model or mine classification rules. Then, this classification rule is used to classify records in other databases. ④ Cluster Analysis Clustering analysis inputs a group of unclassified records, and these records should be divided into several categories without prior knowledge. By analyzing the record data in the database, according to certain classification rules, rationa

Scientific research direction: in universities, research units, enterprise research institutes and other high-level scientific research institutions to study the new algorithm efficiency improvement and future application. Second, talk about the skills required in each area of work.(1). Data
Data How do data mining tools accurately tell you important information that is hidden in the depths of the database? And how do they make predictions? The answer is modeling. Built Modulo is actually creating a model when you know the results and applying the model to situations that you don't know about. For example,
features can effectively prevent the customer churn. ⑥ Change and Deviation Analysis. Deviations include a large amount of potentially interesting knowledge, such as abnormal instances in classification, exceptions to patterns, and expected deviations from observed results, the objective is to find a meaningful difference between the observed results and the reference volume. Managers are more interested in unexpected rules in enterprise crisis management and early warning.

Data", for large-scale graph mining, tens node, billion-level edge(GB), also "big data"; For image data, millions images(TB)Can be called "Big Data" completely. So, to do the scalability of the algorithm must be used in parallel
difference between classification and prediction is that the former is to find a series of models that describe or differentiate between categories of data or concepts, while the latter predicts missing or hard-to-obtain, usually numeric-type data values. The similarity is that they are both predictive tools: categories are
models, such as Bayesian, time series, and association rules, are common models. Different model algorithms can be applied based on different problem features. For example, the product recommendation mentioned in this article is typically suitable for solving with association rules. The typical beer and diapers problems in data mining are basically based on this method. Create a
