Cheng, Y. (author), Krishnakumari, P.K. (author)To analyze inherent and diverse patterns within line-based public transport daily delay occurrences, we introduce a data-driven exploratory analysis focused on the spatial-temporal distribution of these delays. Our approach relies on the utilization of the image pattern recognition technique and k-means clustering algorithm. We extract daily...journal article 2024

Chen, Xi (author), Gao, C. (author), Wang, Zuowen (author), Cheng, Longbiao (author), Zhou, Sheng (author), Liu, Shih Chii (author), Delbruck, Tobi (author)Recurrent Neural Networks (RNNs) are useful in temporal sequence tasks. However, training RNNs involves dense matrix multiplications which require hardware that can support a large number of arithmetic operations and memory accesses. Implementing online training of RNNs on the edge calls for optimized algorithms for an efficient deployment on...journal article 2024

Cheng, Ji (author), Xue, Bo (author), Jiaxiang, Y. (author), Zhang, Qingfu (author)Multi-objective Stochastic Linear bandit (MOSLB) plays a critical role in the sequential decision-making paradigm, however, most existing methods focus on the Pareto dominance among different objectives without considering any priority. In this paper, we study bandit algorithms under mixed Pareto-lexicographic orders, which can reflect...journal article 2024
