Jan 23, 2019· Abstract: Feature selection has been an important research area in data mining, which chooses a subset of relevant features for use in the model building. This paper aims to provide an overview of feature selection methods for big data mining. First, it discusses the current challenges and difficulties faced when mining valuable information from big data.
A cubicwise balance method Here, we propose a cubicwise balance method to provide privacy preserv ing range queries on data cubes. This method is based on data perturbation. However, unlike random data perturbation approaches, the cubicwise bal ance method provides a purposive perturbation on individual cells in a data cube.
The elbow method looks at the percentage of variance explained as a function of the number of clusters: One should choose a number of clusters so that adding another cluster doesn''t give much better modeling of the data. More precisely, if one plots the percentage of variance explained by the clusters against the number of clusters, the first clusters will add much information (explain a lot ...
Introduction to Data Mining Techniques. In this Topic, we are going to Learn about the Data mining Techniques, As the advancement in the field of Information technology has to lead to a large number of databases in various areas.

Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which ...
