Evaluation of shallow and deep learning models for multi-step-ahead time series prediction

We present an evaluation study that compares the performance of deep learning models for multi-step ahead time series prediction. The deep learning methods comprise simple recurrent neural networks, long-short-term memory (LSTM) networks, bidirectional LSTM networks, encoder-decoder LSTM networks,and convolutional neural networks. We provide a further comparison with simple neural networks that use stochastic gradient descent and adaptive moment estimation (Adam) for training. We focus on univariate time series for multi-step-ahead prediction from benchmark time-series datasets and provide a further comparison of the results with related methods from the literature.

Code

We have a unified code for all datasets with proper comments.

• The python notebook for implementation can be found here: Code

Data

We use a combination of benchmark problems that include simulated and real-world time series. The simulated time series are Mackey-Glass, Lorenz, Henon, and Rossler. The real-world time series are Sunspot, Lazer and ACI-financial time series. The dataset used in experiments can be found here: Data

Also we had to pre-process the datasets for our experiments.

• The python notebook for preprocessing can be found here: Preprocessing

Experiments

Overall results (30 runs) for different datasets using different models and training strategies can be found here: Results
