Robust dimension-free estimation of simple random tensors: optimal guarantees under heavy tails and adversarial contamination

Roberto I. Oliveira, Zoraida F. Rico, Philip Thompson

We study robust estimation of simple random tensors of arbitrary order under finite-moment assumptions and adversarial contamination. We propose the first robust e…
