Rewrite the below paragraph in academic style.
The author tries to solve the problem of unsupervised domain adaptation by proposing a learning termed Joint Causality-invariant Feature Learning (JCFL) which exploits both distribution-level and causality-level invariance. Additionally a new Joint Hilbert-Schmidt Independence Criterion (JHSIC) - a kernel based measure was derived to quantify independence between two distributions. Using JCFL as loss objective into several UDA methods shows an improvement in the score of 4 UDA benchmarks as well as in source free DA.
