FedMAP: Personalised Federated Learning for Real Large-Scale Healthcare Systems

A recent study critically examines the finite sample conformal prediction theory in medical applications, highlighting that while conformal prediction (CP) offers statistical guarantees for uncertainty estimates, its practical utility is significantly influenced by the size of calibration samples. This raises questions about the reliability of CP in real-world healthcare settings.

The introduction of FADTI, a novel framework for multivariate time series imputation, leverages a Fourier Bias Projection module combined with self-attention and gated convolution to address the pervasive issue of missing values in datasets from sectors like healthcare and traffic forecasting. This approach enhances the model's ability to adapt to both stationary and non-stationary patterns, improving its generalization capabilities under structured missing patterns.

A recent study published on arXiv investigates the statistical properties of min-max normalized eigenvalues in random matrices, a key area in random matrix theory that has implications for machine learning and data science. The research evaluates a scaling law of the cumulative distribution and derives the residual error during matrix factorization, supported by numerical experiments.

A new technical report presents a hierarchical defense framework for Open Radio Access Networks (O-RAN), focusing on enhancing cybersecurity through quantum-augmented AI and machine learning. The framework consists of three coordinated layers: anomaly detection, intrusion confirmation, and multiattack classification, all aligned with O-RAN's telemetry stack. Extensive benchmarking shows the framework achieves near-perfect accuracy and strong class separability.

The Internet of Vehicles (IoV) is undergoing significant advancements in transportation due to enhanced connectivity and intelligent systems. However, this increased connectivity also exposes vehicles to cyber threats such as Denial-of-Service (DoS) and message spoofing. A new project aims to develop a machine learning-based intrusion detection system to classify malicious traffic on the Controller Area Network (CAN) using the CiCIoV2024 benchmark dataset.

A new framework has been introduced to explore quantum advantage in machine learning, linking the structure of parametrized quantum circuits to the functions they can learn. This analysis reveals how properties like circuit depth and gate count influence the potential for efficient classical simulation versus robust quantum performance.

Recent advancements in low-rank tensor decompositions have been highlighted as crucial for understanding the theoretical foundations of deep neural networks (NNs). These mathematical tools provide unique guarantees and polynomial time algorithms that enhance the interpretability and performance of NNs, linking them closely to signal processing and machine learning.

A new study has introduced a randomized block Kaczmarz method (RBK) that samples data uniformly, addressing the limitations of previous algorithms that required expensive preprocessing. This method shows that iterates converge to a weighted least-squares solution, although bias and variance can be significant. Regularization is proposed to control these issues effectively.
