It was important work because it allowed for achieving better accuracy of the smaller singular values. But lots of work is now available that improves this accuracy.

Thanks for the helpful article.

Where does the “object” local come from, as in “object.class” and “object.errors”? I’m just learning Ruby and Rails, but I can’t make any sense of how this variable is set. Thanks!

very interesting and informative. If you also post its used in information retrieval in the process of latent semantic indexing it will be very helpful for me. Thank you again for the post.

Thank you for a feedback. It is really nice! Unfortunately second part is still in my folder with unfinished stuff… but I promise I will invest some time to finish it and ping you as soon as it is available. Once again… thank you for a kind words!

This was brilliant. Is there a second part somewhere - I want more of this sort of stuff?

Thanks for putting this together!
