A Novel Time Series Prediction Approach Based on a Hybridization of Least Squares Support Vector Regression and Swarm Intelligence

Abstract EN

This research aims at establishing a novel hybrid artificial intelligence (AI) approach, named as firefly-tuned least squares supportvector regression for time series prediction ( F L S V R T S P ) .

The proposed model utilizes the least squares support vector regression (LS-SVR) as a supervised learning technique to generalize the mapping function between input and output of time series data.

In order to optimize the LS-SVR’s tuning parameters, the F L S V R T S P incorporates the firefly algorithm (FA) as the search engine.

Consequently, the newly construction model can learn from historical data and carry out prediction autonomously without any prior knowledge in parameter setting.

Experimental results and comparison have demonstrated that the F L S V R T S P has achieved a significant improvement in forecasting accuracy when predicting both artificial and real-world time series data.

Hence, the proposed hybrid approach is a promising alternative for assisting decision-makers to better cope with time series prediction.
