| Title: | A sample-rebalanced outlier-rejected k-nearest neighbor regression model for short-term traffic flow forecasting | Authors: | Cai, LR Yu, YD Zhang, SY Song, Y Xiong, Z Zhou, T |
Issue Date: | 2020 | Source: | IEEE access, 2020, v. 8, p. 22686-22696 | Abstract: | Short-term traffic flow forecasting is a fundamental and challenging task due to the stochastic dynamics of the traffic flow, which is often imbalanced and noisy. This paper presents a sample-rebalanced and outlier-rejected k-nearest neighbor regression model for short-term traffic flow forecasting. In this model, we adopt a new metric for the evolutionary traffic flow patterns, and reconstruct balanced training sets by relative transformation to tackle the imbalance issue. Then, we design a hybrid model that considers both local and global information to address the limited size of the training samples. We employ four real-world benchmark datasets often used in such tasks to evaluate our model. Experimental results show that our model outperforms state-of-the-art parametric and non-parametric models. | Keywords: | Intelligent transportation systems Road transportation Time series analysis Stochastic processes |
