 ## `MLNI`
 MLNI is a python package that performs various tasks using neuroimaging data: i) binary classification for disease diagnosis, following good practice proposed in [AD-ML](https://github.com/aramis-lab/AD-ML); ii) regression prediction, such as age prediction; and iii) semi-supervised clustering with [HYDRA](https://github.com/evarol/HYDRA).
