Maximum likelihood estimation for tensor normal models via castling transforms
Harm Derksen, Visu Makam, Michael Walter
In this paper, we study sample size thresholds for maximum likelihood estimation for tensor normal models. Given the model parameters and the number of samples, we determine whethe…

Maximum likelihood estimation for matrix normal models via quiver representations
Harm Derksen, Visu Makam
In this paper, we study the log-likelihood function and Maximum Likelihood Estimate (MLE) for the matrix normal model for both real and complex models. We describe the exact number…
