Latent Dirichlet Allocation (Part 1 of 2) 

The first time ever I got what Dirichlet distribution does. Thank you. Very useful explanation.

I literally laughed out loud when "lions" suddenly appeared in one of the corners! You're videos are sheer genius, Dr. Serrano.

BEST LDA videos out there. Stop looking , watch this one and you will finally be happy.

It can't be more perfect. Thanks, Luis for the hard work you put on this video.

I finally understand how does the LDA work. Thank you, lifesaver!

Explaining hard concepts in simple visual representation is a unique genius. Thank you for creating such beautiful contents Dr. Serrano

Luis, you are an absolute gem of a teacher, a complete pedagogical inspiration. In my wildest dreams I couldn't have come up with such a clear way to demonstrate LDA. It's like watching a genius at work :)

Love your explanations! Some of the best out there and really shows what, for most people, the mathematics obfuscates...good stuff!💪🏼🎓👍🏼

I started watching this just for fun, but it's been a while since I last seen something so nicely explained . Congratulations, top quality stuff!

It was awwwwwwwwwwesome....... It's the first time I properly understand that blueprint. Eagerly waiting for part 2

The best description I've ever found on LDA! Thank you very much. The visualization helped a lot.

Super easy to follow. This is honestly the best video on Latent Dirichlet Allocation out there!

Thank you for the visual descriptions! It was extremely difficult to understand beforehand, but your video made it seem so much easier.

I have watched more than 8 videos about LDA on RU-vid. This is the best-explained video about LDA I have watched. Thank you very much.

absolute gem. Can't find any clearer and intuitive explanation of LDA than this.

Thank you so much! I loved your explanation using the analogy of a machine with settings and gears to explain the math! This is amazing.

Hands down the best video on LDA! Great job, Serrano!

Thank you for giving us a so vivid, intuitive illustration for LDA. It is really helpful for me as a newby who just encountered this topic recently.

The best explanation of LDA I have EVER seen ! Thank you so much !

Dr Serrano, you just have put me over the moon. Thank you for your elegant explanation of this complex generative model topic.

Thank you very much for this video. I have watched many similar videos on youtube about the working of LDA. Your explanation is by far - I say by a long way - the most comprehensive and easy to follow. You are a great teacher. I have told my students and friends about your fantastic video.

after all the abstract articles I have read and confusing math symbols I have counted, here's the perfect explaining video and amazing visuals! thank you very very much man!

It was amazing and feel like continuing even after I completed the same in nanodegree. Please do more videos on Probabilistic models for NLP

I loved the way you gave the intuition gently by using the analogies. Great teaching and explanation of the topic.

This is one of the best and concise explainations of this topic that I have seen. Thanks!

This made visualizing each step of topic modeling very clear! Thank you

This is such a great explanation! I’ve only taken one stats class and no computer science but I was able to follow it easily👍🏻

thnak you so much...been reading for months and you sorted out my queries in 26 minutes...wish you well and keep up the great work you've done!

This video is fantastic. Thankyou so much for the interpretation. This is incredibly handy for someone who is very new to data science!! keep doing more!

Best LDA explanation on the internet. Thank you!

legendary explanation, absolutely wonderful

Awesome explanation!!! Now I understand how topic modeling with LDA works, All doubts cleared. Thank you very much

All I can say is I'm just starting this and am very grateful to have the topic explored more, so thank you in advance.

Very intuitive and clear explanation. Thanks a lot, Mr. Serrano!

omg this was the crystal clear explanation even a high school kid can understand the concepts. one great man said "if you can't explain in simple then you haven't understood properly". Big thanks to the channel.

Luis que pasada de video, increíble. Me ha encantado con la facilidad que has explicado este tema que para mí era imposible de planteármelo, estoy deseando seguir con lo que haces es oro.

What an amazing video! The math is what scares me most of the time, but you made it so much more easier. Thanks!

Best video on Dirichlet by a long shot. Thanks!

You are a great teacher! Thank you very much for the detailed and well illustrated explanation!

the quality of this teaching is amazingly good!

Clear, concise and intuitive. Thank you!

The best teacher ever! Excellent job dear Luis :)

This is really good! Great Explanation bro... These videos might take time to prepare, It will stand for a long time to come!

A very clear and easy-to-understand explanation. Thank you so much.

really thanks for your training. every thing is just clear for me now with your video about LDA .

Fantastic explanation. Very clear, excellent use of diagrams. Thank you!

I've been spending years (as a hobby in my free time, not really studying in depth) trying to gain better insight into Bayesian reasoning. Dirichlet distributions and similar topics tend to come up but they are so *loaded* with overly-abstract explanations and overly-formal proofs and such that it is a rare that I actually gain much insight from them. So, just want to say that I really appreciated your use of everyday life and human intuition to explain stuff in this video. I just subscribed to your channel based on this video (and some other vids too, but mainly this one), in the hopes you may continue with topics like this and providing your intuitive examples and such in the future. Thanks a lot, and looking forward to your next vids. 😎👍 P.S.: For a future 'foundational' topic, may I suggest/request the Beta distribution (Dirichlet is like a multi-dimensional extension of the Beta, AFAIUI), and also the Gamma distribution. Indeed, one of the questions that has been bugging me for ages is how on Earth one can write one's own Beta/Gamma/Dirichlet distribution functions that are both accurate and half-decently efficient (not super-efficient, just 'good enough'). And this seems to involve having a working Gamma function (function not distribution), which I'd also like to know how one could write one's own. All the stuff I've read on the Gamma function either a) doesn't explain how to actually implement the function (just theoretical stuff like reflection formulas or whatever), or b) just shows an unintuitive version with all sorts of optimization tricks but without providing understanding. I need something in the middle, with both conceptual and practical together.

This guy is amazing. He made LDA so intuitive.

Amazing. Very well explained. The good thing is you start with the very origin of running LDA, which is Dirichlet distribution. Thank you so much for your effort. Keep it up 👍

I have been looking for this topic all over the internet but couldn't find any, where it is explained this clearly. Thank you :)

I'm currently researching distributed representations, and I wanted to learn about LDA, but I didn't even know what LDA was to begin with. Your video really helped me understand it. Thank you, and I'm eager to keep going and learn more.

Brilliant video. Thanks for your effort! You've made it seem trivial and it's not. Very well explained.

Thank you so much, it's extremely helpful. I'm moving right away to the next video. You're a hero.

Extremely clear, thank you for your teaching!

You are a really good teacher! I really like your illustration and graphs! Thank you very much!

This is the most helpful tutorial on LDA.

Great Video Dr. Serrano. It was really useful for my sentiment analysis!

It takes a genius to make complex things easy. Thanks

a beautiful piece of work. Now I got what LDA is all about

The best explanation on LDA model.

This is an excellent explanation on the topic, thanks so much!

Best explanation of Latent Dirichlet Allocation superb :)

This so beautifully explained, that I wonder why people go to models that are so uninterpretable. Great animation, really, I usually cant focus on videos but this one got me through :)

Very clear! Thank you for the great explanation for Dirichlet distribution. The graphs are really a great way to think of the distribution. Although it might be better to explain the meaning of the subscripts in the formula.

Amazing and very intuitive explanation, thanks for the video!

Thank you for this video. I was able to understand properly with this visualization.

The legend is still alive!!!

Better than all of mit Stanford and Ivy League money monsters combined...gem of an explaination

This is SUCH a good explanation. Thank you!!!

Clear as crystal explanation! Thank you very much

lots of intuition which is greatly appreciated. I spotted the same presenter as a couple of years ago during my ML training with udacity: cool

Perfect and very clear explanation! Good job and thank you very much ^^

this is really a great video! thanks, Luis!

Beautiful explaination to an extremely beginner unfriendly model. Thank you!

This video is pure art.

Very nice explanation of Dirichlet Distribution. Thanks.

Your explanation is an outlier compared with other RU-vidrs for LDA, because it's tooooo goood.

very very very clear explanation, awesome work

awesome! The first time i understand LDA!

Fantastic, Serrano!! Thank you very much!

Absolutely fantastic presentation! Thank you so much!
