All models are incorrect, but some of them are useful.
The root cause of data analysis is to properly resolve the problem, set appropriate mental and statistical models for the data, and make correct judgments. However, it is not guaranteed that the correct answer is obtained for the next time.

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.

I. Background Introduction
Why do we have the best and most experienced staff to leave prematurely. The data came from the Kaggle and tried to predict what the next valuable employee would leave. Analyze the data to see what factors affect the resignation of employees, as well as the main reasons for predicting which outstanding employees will leave. Variable Description:

Deep and simple data analysis is one of the "deep and simple" series of American o'reilly press. This series is characterized by a lot of thoughts on how to make readers more comfortable to read and remember more content in the book. Although the book is thick, there are many illustrations. Illustrations and texts are often mixed together without obvious boundaries. It is really easy to read. It is easier t
production environment. Some other workarounds are used, and the operation steps are cumbersome. How to quickly add a data column with default values and minimize the impact on the existing production environment is a goal we hope to achieve.
This article starts with operations, discusses the problem of adding default data columns, and finally introduces the "revolutionary" optimization of Oracle 11g.
