Travel time analysis and prediction play critical roles in developing Intelligent Transportation systems (ITS), which have attracted significant interests from the research community. Deep learning-based methodologies have proven to be powerful tools in utilizing big data for predicting travel times. However, while most studies have focused on shortterm predictions, predicting travel times over longer periods is equally important for wide applications like traffic management and route planning. Long-term prediction, which often receives less attention due to its complexity, remains a gap in current researches. To address this challenge, we propose the Periodic Stacked Transformer (PS-Transformer), a novel Transformer-based framework designed to enhance both short and long-term traffic predictions. PS-Transformer consists of two primary modules: the Segment Encoding Integration (SEI) and the Periodic Stacked Encoder-Decoder (PSED). SEI module extracts periodic patterns from traffic data, while PSED effectively captures shortterm and long-term dependencies from temporal attributes. Additionally, PSED tackles error accumulation, a common issue in extended prediction periods, through its non-autoregressive decoder design. Our PS-Transformer is validated through a series of experiments on a real-world dataset, demonstrating its capability in multi-step predictions that provide forecasts over an extended duration. Empirical evaluation results show that PS-Transformer outperforms state-of-the-art methods in both short and long-term travel time predictions across various metrics, including MAE, RMSE, and SMAPE.

Recently, digital twins have been paid much attention as a major application towards Beyond 5G/6G network, and real-time object recognition methods are key technology to digitize the real world as a digital twin. However, it is challenging to make a fast and accurate decision on what the object is from real-time streaming information such as video because accurate object recognition algorithms require a huge computation. To satisfy delay requirement of digital twin applications, such computations have to be moved from cloud to edges or even small terminal devices, where computing capacity is very limited. Thus, recognition mechanisms have to be simplified for small devices but they would result in degraded accuracy. In this paper, we focus on the multimodal information processing mechanism of the brain, which makes decisions based on multiple types of uncertain observed information, to improve accuracy of simplified recognition mechanisms. We first propose a unimodal object recognition mechanism based on the Bayesian attractor model, which continuously recognizes objects from noisy streaming media data. Then, we extend the mechanism with Bayesian causal inference to fuse the results of unimodal media recognition. Through computer simulations, we show that our proposed method identifies an object accurately and quickly from uncertain observed information.

With the known vulnerability of neural networks to distribution shift, maintaining reliability in learning-enabled cyber-physical systems poses a salient challenge. In response, many existing methods adopt a detect and abstain methodology, aiming to detect distribution shift at inference time so that the learning-enabled component can abstain from decision-making. This approach, however, has limited use in real-world applications. We instead propose a monitor and recover paradigm as a promising direction for future research. This philosophy emphasizes 1) robust safety monitoring instead of distribution shift detection and 2) distribution shift recovery instead of abstention. We discuss two examples from our recent work.
