LDA Topic Models is a powerful tool for extracting meaning from text. In this video I talk about the idea behind the LDA itself, why does it work, what are the free tools and frameworks that can be used, what LDA parameters are tuneable, what do they mean in terms of your specific use case and what to look for when you evaluate it.

Superb presentation you made. Simply beautiful. The transformation from a distributional bar graph to a DNA strand ... amazing. So many designs and thinkings imbued throughout the presentation. Also, the color choice is great. To be skilled at both the science and the presentation is quite rare IMHO.

@andriusknispelis8627 7 лет назад
Thank you! I really appreciate it. As for the design of it, i just wanted to keep it clean and simple. Also since i made everything in Keynote i took advantage of it's "magic move" effect (that's what's happening there in that slide) :)

Wow! Thank you, this was so immensely helpful, with a real-life example used to illustrate the whole way. Even the things that were highly technical were grounded in the ASDA magazine example and it really helped my comprehension, because everything I'd read before this was very abstract. Keep the videos coming!!
@andriusknispelis8627
@andriusknispelis8627 5 лет назад
Thank you! I have to admit that reason I chose ASDA magazine was because I like their covers :). And the reason I went for that particular issue is because of the green color, since it went well with the rest of the slides :)

Straightforward and elegant explanation. I'm recently venturing into topic modelling for my research work and I was a little bit confused with the differences between keyword extraction and topic modelling and I stacked up many articles to read to learn more about that. However, thanks to my time here, I saved a whole lot of effort and time just by watching this video. This seems to be a good path to follow for splitting documents into conceptual and meaningful segments. Thanks, once again.

@@andriusknispelis8627 I consider your presentation near perfect and more in detail about the process of LDA is probably left to the auditor to inform himself.

When it comes to LDA I'd definitely recommend to watch/read anything from David M. Blei (the author himself) One of his video lectures (1 hour 20 min long) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DDq3OVp9dNA.html When I studied it I haven't watched the videos myself, I just read articles. Here's one I can recommend from him: www.cs.columbia.edu/~blei/papers/Blei2012.pdf I also like this one very much, also I think the title is spot on accurate :) Reading Tea Leaves: How Humans Interpret Topic Models pdfs.semanticscholar.org/3a99/da22b1658695d95a764169e030cc40e2fb95.pdf
