Extremely helpful! Thank you! Also thank you for the blog post link (by the way, the latex isn't rendering)
Hi The blog belongs to Andre Wibisono, you should contact him. I guess he is not maintaining the site anymore. The site is working and showing latex in my machine.
I figured out how to play false tones better
Impressing with the attachment
Very well and clearly explained!, the slides and notes on your website are very useful as well! Thank You!
Thank you for sharing this.
Thanks a lot ;Please i need your help to understand "clustering with Binary Matrix Factorization" My question is ..Why they often put : CT *1=0 as a constraint ; knowing that C is a centroid matrix and G is indicator matrix and B is our binary data matrix.
Thanks for sharing your great research paper! Is that possible to customize the proposed extrapolated alternating algorithms to solve other types of problems, not just approximate canonical polyadic decomposition? Thanks
@@AndersenAng Thanks for your anwser!
Thank you for the presentation. My question, what is the mathematical reason and intuitive reason that can explain why NMF can successfully factorize/decompose the features e.g., roof, grass, tree?
@Man Shun Ang I am sorry, but I still don't get it. All of the roof, grass, and tree are non negative, what is the reason the NMF can separate those? I cannot find any paper that explain this intuitively and mathematically.
