Finite-Time Observability of Oscillatory Instabilities in Synchronous p-bit Dynamics
Naoya Onizawa, Shunsuke Koshita, Takahiro Hanyu
Synchronous update schemes in p-bit annealing offer a natural route to massive parallelism, but they can also induce period-2 oscillations that degrade optimization performance. In…

Casewise and Cellwise Robust Multilinear Principal Component Analysis
Mehdi Hirari, Fabio Centofanti, Mia Hubert +1
Multilinear Principal Component Analysis (MPCA) is an important tool for analyzing tensor data. It performs dimension reduction similar to PCA for multivariate data. However, stand…

MacroPARAFAC for handling rowwise and cellwise outliers in incomplete multi-way data
Mia Hubert, Mehdi Hirari
Multi-way data extend two-way matrices into higher-dimensional tensors, often explored through dimensional reduction techniques. In this paper, we study the Parallel Factor Analysi…
