Special Issue Information

Dear Colleagues,

Machine learning combines high-performance computing, leading to unusual solutions for multi-model data analysis problems. Machine learning-empowered systems can today achieve performance levels in various data analysis tasks comparable to, or even exceeding, those of humans. These advancements have the potential to open new high-impact applications in different environments. In this Special Issue, the authors will use theoretical, methodological, and experimental contributions to fully exploit machine learning solutions in smart applications. The topics will include, but are not limited to:

  1. Lightweight machine learning models for visual and audio data analysis and applications.
  2. Machine learning models for efficient multimodal data analysis and fusion.
  3. Sensor data analysis based on machine learning.
  4. Efficient deep learning methodologies for the Internet of Things.
  5. Machine learning for applications in smart homes, smart lighting.

To address the recognition challenges faced by arrester pointer instruments’ dial scales in various scenarios, this paper introduces a deep learning-based recognition method for pointer instrument scales. An attention module is integrated into the YOLOv5 network architecture, enhancing the accuracy and robustness of the model. After correcting the dial, dial recognition is conducted with OpenCV to achieve precise identification of the instrument scales. The proposed method was tested using images of arrester pointer instruments against diverse backgrounds. The experimental results demonstrate that the method processes instrument data images in an average time of 0.662 s and achieves a successful recognition rate of 96% with an average error of 0.923%. This method provides a rapid and efficient approach for recognizing instrument scales and offers a novel solution for identifying similar types of instruments. Full article

This paper aims to propose an explainable and generalized chemical reaction representation method for accelerating the evaluation of the chemical processes in production. To this end, we designed an explainable coarse-fine level representation model that incorporates a small amount of easily available expert knowledge (i.e., coarse-level annotations) into the deep learning method to effectively improve the performances on reaction representation related tasks. We also developed a new probabilistic data augmentation strategy with contrastive learning to improve the generalization of our model. We conducted experiments on the Schneider 50k and the USPTO 1k TPL datasets for chemical reaction classification, as well as the USPTO yield dataset for yield prediction. The experimental results showed that our method outperforms the state of the art by just using a small-scale dataset annotated with both coarse-level and fine-level labels to pretrain the model.

Multiple station passenger flow prediction is crucial but challenging for intelligent transportation systems. Recently, deep learning models have been widely applied in multi-station passenger flow prediction. However, flows at the same station in different periods, or different stations in the same period, always present different characteristics. These indicate that globally extracting spatio-temporal features for multi-station passenger flow prediction may only be powerful enough to achieve the excepted performance for some stations. Therefore, a novel two-step multi-station passenger flow prediction model is proposed. First, an unsupervised clustering method for station classification using pure passenger flow is proposed based on the Transformer encoder and K-Means. Two novel evaluation metrics are introduced to verify the effectiveness of the classification results. Then, based on the classification results, a passenger flow prediction model is proposed for every type of station. Residual network (ResNet) and graph convolution network (GCN) are applied for spatial feature extraction, and attention long short-term memory network (AttLSTM) is used for temporal feature extraction. Integrating results for every type of station creates a prediction model for all stations in the network. Experiments are conducted on two real-world ridership datasets. The proposed model performs better than unclassified results in multi-station passenger flow prediction. Full article
