1–4 of 4The Radio-Frequency Transformer for Signal Separation
We study a problem of signal separation: estimating a signal of interest (SOI) contaminated by an unknown non-Gaussian background/interference. Given the training data consisting of examples of SOI an...
MERLIN: Building Low-SNR Robust Multimodal LLMs for Electromagnetic Signals
The paradigm of Multimodal Large Language Models (MLLMs) offers a promising blueprint for advancing the electromagnetic (EM) domain. However, prevailing approaches often deviate from the native MLLM p...
Reservoir Subspace Injection for Online ICA under Top-n Whitening
Reservoir expansion can improve online independent component analysis (ICA) under nonlinear mixing, yet top-$n$ whitening may discard injected features. We formalize this bottleneck as \emph{reservoir...
A 1/R Law for Kurtosis Contrast in Balanced Mixtures
Kurtosis-based Independent Component Analysis (ICA) weakens in wide, balanced mixtures. We prove a sharp redundancy law: for a standardized projection with effective width $R_{\mathrm{eff}}$ (particip...
