Randomizing Quantum Walk

2020 · arXiv (Cornell University)

The evolution of a walker in standard "Discrete-time Quantum Walk (DTQW)" is determined by coin and shift unitary operators. The conditional shift operator shifts the position of the walker to right or left by unit …

Cross-cluster precision-guided knowledge fusion for fair and personalized federated learning

2025 · Alexandria Engineering Journal

We propose a Personalized Precision-Centric Clustered Federated Learning (PPCFL) framework to address statistical heterogeneity and model personalization challenges in Federated Learning. PPCFL introduces a layer-wise, angular dissimilarity-based clustering mechanism that groups nodes with similar optimization …
