The Hybrid Grid Partition and Rough Set Method for Generating Fuzzy Rules in Data Set Classification: Overcoming High Dimensional Data Challenges

In the realm of data classification, the fuzzy rule-based system with a grid type fuzzy partition method has proven to be an effective approach in dealing with low-dimensional data patterns. This system offers good classification capabilities and satisfying interpretation. However, in high-dimensional data, the problem of increasing the number of rules still arises, thereby reducing interpretation and accuracy of system classification. This study aims to develop new methods in producing fuzzy rules for data set classification, focusing on overcoming the challenges posed by high-dimensional data.

The Need for a Hybrid Approach

The conventional grid fuzzy partition method has been widely used in data classification due to its simplicity and effectiveness in low-dimensional data. However, as the dimensionality of the data increases, the number of rules generated by this method also increases exponentially, leading to a decrease in interpretation and accuracy. This is because the grid partition method divides the input space into a fixed number of regions, resulting in a large number of rules that are often redundant and difficult to interpret.

The Hybrid Grid Partition and Rough Set Method

To address the challenges posed by high-dimensional data, this study proposes a hybrid method that combines the grid partition method and the rough set method. The hybrid method works as follows:

Formation of Grid Structure

The grid partition method is modified to form a more efficient grid structure. This involves dividing the input space into a smaller number of regions, while still maintaining the ability to capture the underlying patterns in the data.

Reduction of Attributes with Rough Set

The rough set method is used to produce attribute reduction sets based on the level of precision or variable errors. This involves identifying the most relevant attributes that contribute to the classification of the data, and reducing the number of attributes to a smaller set.

Data Reduction

The data in the post-reduct information system table is analyzed to identify the redundancy pattern of the condition and target attribute value. This allows a reduction in the number of attributes and objects, resulting in a more efficient and accurate classification system.

Promising Results: Increase Accuracy and Reduce the Number of Rules

The results of this study showed that the Grid and Rough Set partition hybrid method was able to produce a number of rules that did not increase exponentially, with higher classification accuracy. The accuracy of the hybrid method was 83.33%, which is far better than the conventional grid fuzzy partition method, which only reached 66.67% accuracy.

Benefits of the Hybrid Method

The hybrid method offers several benefits, including:

Increased Accuracy

The hybrid method has succeeded in increasing classification accuracy compared to traditional Grid Fuzzy partition methods. This is because the rough set method is able to identify the most relevant attributes and reduce the number of attributes, resulting in a more accurate classification system.

Reduction of the Number of Rules

The rough set method is effective in reducing the number of attributes and objects, thereby reducing the number of rules that need to be raised. This results in a more efficient and easier-to-interpret classification system.

Better Interpretation

With a smaller number of rules, the interpretation of the classification system becomes easier and more transparent. This is because the hybrid method is able to identify the most relevant attributes and reduce the number of attributes, resulting in a more interpretable classification system.

Conclusion

The Grid and Rough Set partition hybrid method offers an innovative approach in dealing with high-dimensional data classification problems. This method succeeded in combining the strength of the two methods to produce a more efficient, accurate, and easily interpreted fuzzy classification system. The results of this study demonstrate the effectiveness of the hybrid method in increasing accuracy and reducing the number of rules, making it a promising approach for data classification in high-dimensional data.

Future Directions

Future research directions include:

Application of the hybrid method to real-world data sets: The hybrid method should be applied to real-world data sets to demonstrate its effectiveness in practical applications.
Comparison with other classification methods: The hybrid method should be compared with other classification methods, such as decision trees and support vector machines, to demonstrate its superiority.
Extension to other domains: The hybrid method should be extended to other domains, such as image classification and text classification, to demonstrate its versatility.

By addressing the challenges posed by high-dimensional data, the hybrid Grid Partition and Rough Set method offers a promising approach for data classification in a wide range of applications.
