Summary: Convolutional Neural Networks (CNNs) can achieve state of the art results for visual recognition problems when the data distributions are the same between train and test sets and all test set classes are present in the training data. However, in the real world, where data evolves and new classes emerge, traditional neural networks fail to identify unknown classes. Open-Set Classification research field provides potential solutions for this problem. In this study, a system called DeepStreamOS is proposed, which combines deep neural network activations with a stream-based outlier detection method to quickly identify instances belonging to unknown classes. Experimental results demonstrate that DeepStreamOS outperforms other open-set classification methods in most scenarios and significantly improves the speed of classification.

Summary: The development of mobile and wearable devices has enabled various applications that measure and improve our daily lives, such as activity tracking, wellness monitoring, and human-computer interaction. Many of these applications rely on low-power sensors in these devices to perform human activity recognition (HAR). In recent years, deep learning has made significant advancements in HAR on mobile and wearable devices. This paper categorizes and summarizes existing work on deep learning methods for wearables-based HAR, and provides an analysis of the current advancements, developing trends, and major challenges.

Summary: This article proposes a new paradigm for automatically designing a suitable CNN architecture for remote sensing scene classification. The more efficient RS-DARTS search framework is adopted to find the optimal network architecture, with new strategies introduced in the search phase, noise added to suppress skip connections, and sampling to reduce redundancy in exploring the network space. Extensive experiments demonstrate the effectiveness of the proposed method in classification performance and search cost compared to other methods.

Summary: This study evaluates the influence of image contrast, human anatomy, sampling pattern, undersampling factor, and noise level on the generalization of a deep cascade of convolutional neural network (DC-CNN) for image reconstruction from undersampled k-space data. The results show that reconstruction quality is highly sensitive to sampling pattern, undersampling factor, and noise level, and less sensitive to image contrast. Deviation in human anatomy between training and test data leads to reduction in image quality, particularly for brain datasets. Transfer learning shows potential for image reconstruction from different datasets than those used for training.

Summary: Evolutionary Neural Architecture Search (ENAS) is an automated method for designing deep network architecture, which has gained extensive attention in the field of automated machine learning. This paper proposes improvements in two aspects: the introduction of efficient CNN-based building blocks and a triplet attention mechanism to enhance the effectiveness and classification performance of the generated architectures, and the use of a random forest-based performance predictor to reduce computation in training. Experimental results demonstrate that the proposed algorithm significantly reduces computational resources while achieving competitive classification performance on the CIFAR dataset.
