Automatic deep learning for trend prediction in time series data
This work addresses the need for stable and efficient model updates in dynamic systems, but it is incremental as it applies existing AutoML techniques to a specific domain.
The paper tackled the problem of automating deep neural network model development for trend prediction in time series data, using an AutoML tool to find optimal configurations that performed comparably to manual methods across four datasets.
Recently, Deep Neural Network (DNN) algorithms have been explored for predicting trends in time series data. In many real world applications, time series data are captured from dynamic systems. DNN models must provide stable performance when they are updated and retrained as new observations becomes available. In this work we explore the use of automatic machine learning techniques to automate the algorithm selection and hyperparameter optimisation process for trend prediction. We demonstrate how a recent AutoML tool, specifically the HpBandSter framework, can be effectively used to automate DNN model development. Our AutoML experiments found optimal configurations that produced models that compared well against the average performance and stability levels of configurations found during the manual experiments across four data sets.
