Autonomous robot delivery systems promote sustainable urban development and consumption. To study users’ intentions to switch over or resist autonomous robot delivery systems, this study has applied the integrated user resistance model and innovation resistance theory to develop a model. Surveys were distributed to 637 residents residing in Singapore and analyzed using structural equation modeling. The findings support all nine hypotheses and confirm the proposed relationships between the variables in the proposed model. Therefore, this study enriches understanding of consumers’ decision-making processes pertaining to switching costs and switching benefits and allows for a more in-depth understanding of switching and resistance behaviors. Furthermore, the total effect analysis indicates that switching costs have the highest total effect on resistance while switching benefits have the highest total effect on intentions to switch to autonomous robot delivery systems. This information can be used in businesses’ marketing strategies to reach a bigger audience.

The electricity generation through wind energy is rapidly expanding, primarily due to its priorities of lower carbon emissions and sustainability. Precise wind speed forecasting is essential for renewable energy conversions as it mitigates the randomness of wind power, therefore aiding in more effective control and strategic planning for power system dispatch. However, the inherent fluctuation of wind speed challenges accurate and consistent time series forecasting. In this paper, we develop a novel parsimonious channel mixing ensemble deep random vector functional link (pcm-edRVFL) network to anticipate future wind speeds. The ensemble deep random vector functional link network (edRVFL) utilizes deep feature extraction and ensemble learning to improve forecasting performance. We refined the standard edRVFL model by incorporating a parsimonious channel mixing selection approach for input data, focusing on crucial historical observations, and strengthening the representation of each explanatory variable. We conduct extensive evaluations on four wind speed datasets using the proposed model, and the comparative experiment results demonstrate its superiority over other baseline models. Our proposed pcm-edRVFL network provides a practical approach for precise and efficient wind speed forecasting, proving to be an instrumental resource in wind energy design and operation systems.

This paper proposes a three-stage online deep learning model for time series based on the ensemble deep random vector functional link (edRVFL). The edRVFL stacks multiple randomized layers to enhance the single-layer RVFL's representation ability. Each hidden layer's representation is utilized for training an output layer, and the ensemble of all output layers forms the edRVFL's output. However, the original edRVFL is not designed for online learning, and the randomized nature of the features is harmful to extracting meaningful temporal features. In order to address the limitations and extend the edRVFL to an online learning mode, this paper proposes a dynamic edRVFL consisting of three online components, the online decomposition, the online training, and the online dynamic ensemble. First, an online decomposition is utilized as a feature engineering block for the edRVFL. Then, an online learning algorithm is designed to learn the edRVFL. Finally, an online dynamic ensemble method, which can measure the change in the distribution, is proposed for aggregating all layers' outputs. This paper evaluates and compares the proposed model with state-of-the-art methods on sixteen time series.

Hospitals can predetermine the admission rate and facilitate resource allocation based on valid emergency requests and bed capacity estimation. The excess unoccupied beds can be determined with the help of forecasting the number of discharged patients. Extracting predictive features and mining the temporal patterns from historical observations are crucial for accurate and reliable forecasts. Machine learning algorithms have demonstrated the ability to learn temporal knowledge and make predictions for unseen inputs. This paper utilizes several machine learning algorithms to forecast the inpatient discharges of Singapore hospitals and compare them with statistical methods. A novel ensemble deep learning algorithm based on random vector functional links is established to predict inpatient discharges. The ensemble deep learning framework is optimized in a greedy layer-wise fashion. Several forecasting metrics and statistical tests are utilized to demonstrate the proposed method's superiority. The proposed algorithm statistically outperforms the benchmark with a ranking of 1.875. Finally, practical implications and future directions are discussed.
