Title: "LOS/NLOS Classification for UAV Communications: A Time-Frequency Multimodal Learning Approach"
Authors: Mingze Pan, Ying Wang
Date: Feb 2025
Accepted: 59th Annual Conference on Information Science and Systems (CISS)
In communication networks, distinguishing between line-of-sight (LOS) and non-line-of-sight (NLOS) is critical for optimizing signal quality, coverage and network reliability. It influences network design, frequency band selection, and technology choices to ensure efficient and reliable communications. In this paper, we design an noval multimodel detection method to distinguish LOS and NLOS communication scenarios. This method combines time-domain channel characterization with frequency-domain spectrogram analysis, Time-Frequency Multimodal Detection (TFMD).
Title: "FiCo: A Fingerprinting-based Two-step Learning-to-learn Approach Combing Vibration and 5G Communication for UAV Classification"
Authors: Xinyi Li, Yifeng Peng, Ying Wang
Date: January 2025
Publication: 2025 IEEE International Conference on Communications (ICC)
Unmanned Aerial Vehicles (UAVs) are widely utilized across industries, necessitating robust security measures. RF fingerprinting based UAV identification can enhance UAV authentication and authorization by identifying unique RF signals, bypassing vulnerabilities of software-based methods. However, its effectiveness can be limited by environmental factors such as distance, interference, and multi-path propagation. To address the challenges of UAV identification, we propose a novel lightweight two-step learning-to-learn classification approach, FiCo, which integrates multiple data sources from diverse domains, including mechanical vibration and 5G communications. In the first step, we employ two Extreme Gradient Boosting (XGBoost) models to separately analyze communication and vibration data from UAVs. In the second step, a Logistic Regression meta-network is utilized to jointly learn from the predictions of these two XGBoost models. Experimental results show that the FiCo method boosts the AUC to 0.9792 and the accuracy to 92.59%. This represents a 2% accuracy increase over the Data Combined method and it improves accuracy by 9.3% with communication data alone and by 5.6% with vibration data alone, raising the AUC by 0.088 and 0.029, respectively. This approach reduces computational complexity and requires fewer training samples, enabling faster and more agile UAV identification in practice.
Title: "Qsco: A Quantum Scoring Module for Open-Set Supervised Anomaly Detection"
Authors: Yifeng Peng, Xinyi Li, Zhiding Liang, Ying Wang
Date: December 2024
Publication: The Thirty-Ninth AAAI Conference on Artificial Intelligence (AAAI-25)
Open set anomaly detection (OSAD) is a crucial task that aims to identify abnormal patterns or behaviors in data sets, especially when the anomalies observed during training do not represent all possible classes of anomalies. The recent advances in quantum computing in handling complex data structures and improving machine learning models herald a paradigm shift in anomaly detection methodologies. This study proposes a Quantum Scoring Module (Qsco), embedding quantum variational circuits into neural networks to enhance the model's processing capabilities in handling uncertainty and unlabeled data. Extensive experiments conducted across eight real-world anomaly detection datasets demonstrate our model's superior performance in detecting anomalies across varied settings and reveal that integrating quantum simulators does not result in prohibitive time complexities. At the same time, the experimental results under different noise models also prove that Qsco is a noise-resilient algorithm. Our study validates the feasibility of quantum-enhanced anomaly detection methods in practical applications.

To ensure the security and reliability of 5G wireless communication protocols, formal verification is employed to guarantee protocol correctness. Given the complexity and scale of 3GPP protocols, automating the formal modeling process is essential, as it can help security experts extract formal properties and dependencies and subsequently build the formal code. This paper introduces a novel Cross-Attention Large Language Model (CAL), a unique classification model specifically designed for this purpose. The study highlights the strengths, weaknesses, and optimal application scenarios for each model. The results demonstrate the feasibility of automating formal verification for complex communication protocols, ensuring their trustworthiness.

Title: "QRNG-DDPM: Enhancing Diffusion Models through Fitting Mixture Noise with Quantum Random Number "
Authors: Yifeng Peng, Xinyi Li, Ying Wang
Date: August 2024
Publication: IEEE International Conference on Quantum Computing and Engineering (QCE)
Recent research has demonstrated that the denoising diffusion probabilistic model (DDPM) can generate high-quality images in artificial intelligence (AI), showing its distinctive capabilities. However, despite this, the diversity of generated images is often limited by the predictability of traditional pseudo-random number generators in the stochastic process. To address this problem, this paper proposes a new mixed noise model based on quantum random numbers QRNG-DDPM. By operating on single qubits, we generate quantum random numbers and apply a self-developed encoding scheme to convert the quantum random numbers into distributions suitable for noise models. Due to the inherent unpredictability of quantum phenomena, quantum random numbers offer a higher level of randomness and diversity compared to traditional pseudo-random numbers.

Publication: IEEE Access (Accepted)
Chest X-rays have played an indispensable part in medical diagnosis for several decades. However, there is a scarcity of experts who can interpret these images to diagnose critical illnesses, which can lead to preventable fatalities. This paper introduces a novel Rapid AI Diagnosis at Edge using Ensemble Models for Radiology (RAIDER) designed to leverage the advantages of cross-geolocation meta-learning models. We can generate local machine learning models at individual locations and distribute them across other locations for diagnosing diseases at the edge or on-premises if required before they become worldwide pandemics, significantly enhancing the rapid or near-real-time identification of fast-spreading respiratory diseases through online learning. This novel approach allows for geo-distributed multi-fold model training, harnessing the unique strengths of diverse geographical data sources to improve diagnostic accuracy and speed by leveraging edge computing. Using the existing Convolutional Neural Network (CNN) models and distributed training at the edge, we can enhance the accuracy and cost-effectiveness of diagnosis. The proposed architecture allows for distributed training and independently verified performance metrics on the MIMIC-CXR and COVIDGR chest X-ray datasets with accuracy, sensitivity, specificity, F1-score, and AUC of 97.80%, 97.06%, 98.48%, 96.51%, and 0.9739, respectively. Our proposed RAIDER architecture marks the first implementation of a collaborative framework that facilitates seamless interaction across different geographic locations and edge computing, enabling a more effective and efficient response to emerging health threats.
