What is the main purpose of data filtering? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The main purpose of data filtering is to find out the kind of data you need. Under the environment of big data, the amount of data accumulates rapidly. in order to analyze the value of massive data, it is very important to screen out valuable data. Data filtering plays an important role in the whole data processing process.

Data screening plays an important role in mathematical modeling. It is the first step of mathematical modeling, only when we get good data can we ensure the authenticity and accuracy of the results. In practical problems, the amount of data we encounter is often huge.

In order to ensure that the method we use can be implemented with the support of the original data, we must filter the data to simplify the solution. At the same time, we should ensure that the screened data are representative and make the results more accurate and true. The ultimate goal of data filtering applied to the computer industry is to prepare for data mining.

Data filtering includes three parts: data extraction, data cleaning and data loading.

Purpose

The purpose of data filtering is to improve the availability of the relevant data collected and stored before, which is more conducive to later data analysis.

The value of data lies in the information it can reflect. However, when collecting data, we do not fully take into account the future use, and only collect data as much as possible.

The second is that in order to obtain the information contained in the data at a deeper level, it may be necessary to aggregate different data sources and extract the required data from them. however, it is necessary to solve the problems that may arise, such as different data structures in different data sources, different names or different representations of the same data.

It can be said that the main purpose of data filtering is to find out some kind of data needed; the ultimate goal is to prepare for data mining.

This is the end of the answer to the question about what is the main purpose of data filtering. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
