 ## Evaluating and Extending Unsupervised VideoSummarization Methods
 
 1. Reproduce unsupervised method CSNet and RL-method SUM-Ind.
-2. Evaluating SUM-GAN-AAE, SUM-GAN-sl, CSNet, and SUM-Ind using F1-score and rank correlation coefficients.
+2. Evaluating [SUM-GAN-AAE](https://core.ac.uk/download/pdf/286400027.pdf), [SUM-GAN-sl](http://doi.acm.org/10.1145/3347449.3357482), [CSNet](https://ojs.aaai.org//index.php/AAAI/article/view/4872), and [SUM-Ind](http://www.openaccess.hacettepe.edu.tr:8080/xmlui/handle/11655/11953) using F1-score and rank correlation coefficients.
 2. Extending CSNet with features variation by applying fusion techniques.
