Analysis of the Accuracy Level of the Fuzzy Sugeno and Tsukamoto Inference Model in Predicting the Inflation Rate in North Sumatra

Introduction

Fuzzy logic is a powerful tool in handling uncertain data, making it an ideal choice for various applications, including predicting inflation rates. In this study, we aim to analyze the accuracy level of two fuzzy inference models, namely the Fuzzy Sugeno and Tsukamoto models, in predicting the inflation rate in North Sumatra. The prediction results of the two models are then compared with actual data to determine which model is more accurate.

Background of Fuzzy Logic and Fuzzy Inference Models

Fuzzy logic is an extension of traditional reasoning that allows an element to become a member of a set with a certain degree of membership (μ). This ability to map uncertain values makes it an ideal tool in the fuzzy inference model. The fuzzy inference model is often used in various cases to produce clear and certain outputs from uncertain data. The two fuzzy inference models used in this study are the Fuzzy Sugeno and Tsukamoto models.

Fuzzy Sugeno Model

The Fuzzy Sugeno model is a type of fuzzy inference model that uses a linear combination of the input variables to produce the output. This model is widely used in various applications, including control systems and decision-making systems. The Fuzzy Sugeno model is known for its simplicity and ease of use, making it a popular choice among researchers and practitioners.

Fuzzy Tsukamoto Model

The Fuzzy Tsukamoto model is another type of fuzzy inference model that uses a non-linear combination of the input variables to produce the output. This model is known for its ability to handle complex relationships between the input variables and the output. The Fuzzy Tsukamoto model is widely used in various applications, including control systems and decision-making systems.

Methodology

This study aims to analyze the accuracy level of the Fuzzy Sugeno and Tsukamoto models in predicting the inflation rate in North Sumatra. The prediction results of the two models are then compared with actual data to determine which model is more accurate. The analysis shows that the level of accuracy of the Fuzzy Sugeno model is influenced by multiple linear regression values. That is, the Fuzzy Sugeno model is more accurate in predicting the inflation rate if the data used to train the model has a strong correlation with variables that affect inflation.

On the other hand, the level of accuracy of the Fuzzy Tsukamoto model is influenced by the accuracy of the input value. The Fuzzy Tsukamoto model is more accurate in predicting the inflation rate if the input data given has a more appropriate value.

Results

From the test results of the inflation rate case in North Sumatra, the Fuzzy Tsukamoto model shows a higher accuracy compared to the Fuzzy Sugeno model. This indicates that the Fuzzy Tsukamoto model is more effective in predicting the inflation rate in North Sumatra, especially if the input data given has a high level of accuracy.

Conclusion

This study shows that the Fuzzy Tsukamoto inference model is more accurate in predicting the inflation rate in North Sumatra compared to the Fuzzy Sugeno model. These results are important in determining a more effective model to predict the rate of inflation in the future.

Suggestion

Researchers are advised to examine more in the influence of significant economic variables on the rate of inflation in North Sumatra to increase the accuracy of the Fuzzy Tsukamoto model.
It is important to ensure that the input data used to train the fuzzy model has high accuracy so that the model can produce accurate predictions.
Subsequent research can be done by comparing the Fuzzy Tsukamoto model with other predictive models, such as multiple linear regression models or Arima models, to get a more comprehensive understanding of inflation rate predictions in North Sumatra.

Implications

By understanding the factors that influence the accuracy of the fuzzy inference model, as well as by utilizing the right data, the fuzzy model can be an effective tool in predicting the rate of inflation and helping decision makers in developing more effective economic strategies.
