Transportation mode detection (TMD) is a context-aware computing technology with significant potential in several applications. However, the development of TMD technologies for real-world scenarios remains challenging, including user-independent evaluations and multimodal analyses. In this study, our team (HYU-CSE) suggested a TMD model as part of the Sussex-Huawei Locomotion (SHL) recognition challenge, and we used the SHL motion and location data. The proposed TMD model was based on the DenseNet architecture, and post-processing using voting schemes was applied to refine the detection performance. The results suggested that the proposed method achieved 94.13% of an F1 score with userindependent analysis. We hope that our study will ultimately help in the design of better TMD applications.

With the assistance of deep learning (DL), website fingerprinting (WF) attacks, which enable a local passive attacker to ascertain the website visited by a user, even when utilizing an anonymous network such as Tor, have become increasingly effective. Nevertheless, the majority of these attacks necessitate a substantial amount of labeled data, posing a practical burden. Recent attempts at mitigating this issue involve the utilization of auxiliary data. However, these methods either require the auxiliary data to be labeled or fail to achieve satisfactory results. In this study, we propose a novel approach that leverages autoencoders to better exploit the unlabeled auxiliary data. Through the reconstruction task, the network learns to extract representative features, thereby enhancing the classifier's performance. We validate the efficacy of our method, which outperforms competing algorithms in the majority of our experimental setups, encompassing both closed-world (CW) and open-world (OW) scenarios.

Quantum computing, taking advantage of its parallel computing, is expected to provide exponential acceleration on some difficult problems. It is one of the important directions for the leapfrog development of computing power in the future. However, due to the limitation of the number of quantum bits, coherence time, fidelity and other factors, the computing power of quantum computers has not been fully utilized at the current stage. In recent years, researchers have proposed a variety of quantum computing performance benchmarks to evaluate and research the performance of quantum computers from the bit, circuit, system, application and other levels. However, the existing performance benchmarks cannot directly evaluate the ability of quantum computers to solve specific problems. Considering the above problems, this paper proposes a VQA-classification-algorithm-oriented performance benchmarks for quantum computing, which takes the classification effect under different data scales as one of the evaluation indicators. This benchmark can comprehensively evaluate the ability of quantum computers to solve data classification problems from the three dimensions of scale, speed, and quality. The benchmark was used to evaluate the superconducting quantum computer and simulator of the IBM and Huawei quantum platform, and its effect was verified experimentally.
In this paper, we study how to optimize the resource allocation and scheduling in art data recognition task by AI algorithm to improve the recognition efficiency and accuracy. This study first analyzes the main challe...

The convergence of SGD based distributed training algorithms is tied to the data distribution across workers. Standard partitioning techniques try to achieve equal-sized partitions with per-class population distribution in proportion to the total dataset. Partitions having the same overall population size or even the same number of samples per class may still have Non-IID distribution in the feature space. In heterogeneous computing environments, when devices have different computing capabilities, even-sized partitions across devices can lead to the straggler problem in distributed SGD. We develop a framework for distributed SGD in heterogeneous environments based on a novel data partitioning algorithm involving submodular optimization. Our data partitioning algorithm explicitly accounts for resource heterogeneity across workers while achieving similar class-level feature distribution and maintaining class balance. Based on this algorithm, we develop a distributed SGD framework that can accelerate existing SOTA distributed training algorithms by up to 32%.
