Shrinkage covariance estimation: LedoitWolf vs ...
When working with covariance estimation, the usual approach is to use a maximum likelihood estimator, such as the EmpiricalCovariance. It is unbiased, i.e. it converges to the true (population) cov...scikit-learn.org/stable/auto_examples/covariance/plot_covariance_estimation.html -
