The previous article introduced the ARFF format, which is a proprietary WEKA format. Generally, We need to extract or obtain data from other data sources. WEKA supports conversion from CVS or from databases. The interface is shown in figure
The WEKA installation directory contains a data directory containing some test data for testing and learning.
Importing data is just the beginning. We also need to pre-process the data. Data preprocessing)

Learning to hash with its application to big data retrieval and mining
Overview
Nearest Neighbor (NN) Search plays a fundamental role in machine learning and related areas, such as information retrieval and data mining. hence, there has been increasing interest in NN search in massive (large-scale) data sets in this big data era. in actual real applications, it'

A data mining project is a project that involves a lot of links and is highly dependent on data. So it's just too normal to encounter a pit in one of these processes.Unclear demand is the first big hole. Unclear demand will take the back of the analysis of the direction of the ditch ditch inside, it is easy to be forced to accept some of the impossible to complete the excavation goals and business objectives.

Chapter 3 issues
Data mining is not easy because the algorithms used become very complex and data is not always available in one place. It needs to be integrated from a variety of heterogeneous data sources. These factors also cause problems. In this tutorial, we will discuss the main issues:
Mining Methods and user interaction
Performance problems
Various data types
