Table 6
The strength and weakness of the models of deep machine learning.
| Methodology | Advantages | Disadvantages |
| Convolutional neural networks | (i) Capable of learning features from local connections and composing them into high-level representation. | (i) Computationally expensive as a huge kernel is needed for feature extraction. | (ii) Classification is less time-consuming. | (ii) A vast dataset is required. | (iii) Can automatically extract features. | (iii) Traffic data needs to be converted to an image. | ā | (iv) No available strategies are available on CNN model depth and parameter selection. | Recurrent neural network | (i) Shows excellent performance in processing sequential data flow. | (i) Long-term dependency results in bad performance. | (ii) Efficient in sequence classification. | (ii) No available firm guideline in dependency elimination. | (iii) Efficient in processing time-series with long intervals and postponements. | ā | Extreme learning machine | (i) Fast learning speed | (i) Training time increases with the hidden node rise. | (ii) Can avoid local minima. | (ii) Unlabelled data problem. | (iii) Modified models are available to deal with an unlabelled data problem. | (iii) May produce less accurate results. |
