I'm pretty sure you forgot to mention that starting terminal (S in this case) needs to be in the top row cell, otherwise the string is not part of the grammar.
@Gazi Mashrurif you are talking about 𝐴,𝑆 and 𝑆,𝐴 which are written in the grid they mean the same thing because the comma denotes OR and order doesn't matter. HOWEVER, if you are talking about 𝐴𝑆 and 𝑆𝐴 which are produced by the cartesian product then they are not the same, order matters in this case.
You are a legend. I tried to figure this out for hour and a half. You managed to basicaly explain it in 4 minutes. The rest was just you showing it for better understanding. i love it.
The best one simply because you showed the different substring combinations you could get and why we could represent those with the values we derived before. Also easier to connect this with why it has to be in Chomsky-normal-form because we need binary derivations for the cartesian products. Not sure everyone who made a video on this understands that. Thank you!
Important note: After you finish this CYK algorithm, if the starting symbol of the grammar (in this case S) is in the top-row (last row) of our procedure, then the given input string is part of the grammar, otherwise it is not. In this case S is part of {S, A, C} which means that the given input string "baaba" is part of the grammar defined by the production rules. The time complexity of the CYK algorithm is O(n^3) where n is the length of the input string (in this case "baaba", so n=5).
And I was trying to avoid this question from Unit 4 of my Pattern Recognition Course. Now I'm gonna attempt this specifically. Thanks for clarifying so well!
This is going to sound like a stupid question, but here goes... Isn't this algorithm supposed to find the most likely syntax structure of a sentence given its words? I've seen other tutorials using strings like "baaba", but I'm lost as to how that relates to the task at hand (parsing a sentence for noun phrase, verb phrase, etc etc.) This isn't a critique of your video, I'm just not seeing the connection yet!
It's rare to find a complex concept explained so clearly. Fantastic work. Hope your voice is better now :)

@Gazi Mashrur I have no idea what this video is at the moment. But I will check tomorrow or the day after and will let you know, if I find out.
@@dofkaw It has been 2 years since you first saw it, probably because of uni, do you actually use this?:p

@Gazi Mashrur yes it is . idk f im too late but it is for anyone concerned
It's called start variable tho, not terminal
absolutely the best, I watched three videos before this one but none of them explained this clearly as you did
You sound truly miserable in this video but now I understand the CYK algorithm, so thanks!
lmao
he sounds like he's being held at gunpoint to explain this
Lol
You are a legend. I tried to figure this out for hour and a half. You managed to basicaly explain it in 4 minutes. The rest was just you showing it for better understanding. i love it.
Not even my teacher explained it this clearly. Thank you very much sir. Helped a lot.
After many years, still a gold to watch. Your video is better than all free AI explanations.
Probably one of the best explanations for beginners to the algorithm. Thanks!
Thank you so much. Was studying for finals and you explained the concept better than the PhD professor.

In a Foundations of CS masters course right now. This video is so much better than the explanation my professor gave. Thank you!
thank you so much, I appreciate it! It was the best video that I've found, it explains easily the CYK algorithm!
this video was better than lecture, office hours, textbook, websites, other solutions. Thanks so much!
Really appreciate your explanation , it’s really helpful for me , I was very frustrated with the textbook.
Holy fuck, it's not Indian lol
made my day
Bro explained this so well. Such a hard concept

Finally ! a very well explained example. Thank you very much !
I searched for a good explanation in the last 3 days and none of them was good, but your explanation is great! Finally understood this thing :D
Best explanation. Couldn't have figured this out without it. You're doing the lord's work man. 10/10
Great Work Out There Buddy.
I gonna have a 'formal language and autamata ' exam in university
and this video really helped me..
thank you so so much. I was stuck and resourced to TH-cam. I wish there are more people like you
THE BEST TUTORIAL! THANK YOU FROM ROMANIA!
WoW you just saved my life, I have a test on this in 2hours and 15 min were enough to understand thanks to you
And I was trying to avoid this question from Unit 4 of my Pattern Recognition Course. Now I'm gonna attempt this specifically. Thanks for clarifying so well!
Loved Your explanation of this video on this topic
0:00 "hello everyone"
me: *falls asleep*
Thanks for the clear explanation. Need it for my exam at the university
It's important that the final cell contains the start symbol of the grammar. Otherwise, the string can't be produced
Also note that the algorithm works on grammars in Chomsky normal form
Best. My paid online tutor cannot explain this good.Awesome explanation.
Thank you soooooo much!!!!! This is the best video I've ever seen on this topic. It's a lot better than the lecture conducted by my professor.
Finally someone did a clear explanation. Thanks.
Very good explanation thank you sir!
Thank you so much, dude!!!! you totally nailed it with your explination. I know it's a little bit late but I hope you got well quickly!!!
This was helpful and, surprisingly, intuitive as promised.
The useful video ever about this algorithm! Thanks.
Thanks alot watched many videos but none of them explained so clearly..
Wow I want this voice to put me to sleep every night
Only after this video I finally got it! Thank you so much!
Great explanation, Thanks!
Woah.. Beautifully explained.. This ones simple as hell .. Thanks a ton
That was a legitimately awesome explanation! Thanks a ton!
Very well explanned i completly get it now, ill get better result on the exam because of this haha
best video out there on CYK example
Awesome tutorial! Crisp and clear.
very good explanation saved me a lot of time!! Cheers!!
Great video, very easily explained.
Great explanation
Very helpful video! Thanks :D
Thank you bro now I also get how the index works in the pseudo code!
Tnx a lot man... Best video about CYK algorithm so far
Superb explanation! Thank you lots.
The best ever easy and clear, wish you will get well and you can speak loud :)
Thank you, it helped me in understanding CKY Parsing for Grammer in NLP.
Very good explanation. Thank you!
Thank you so much!!! This really help me for tomorrow exam😭😭
Qué grande capo!! Barrilete cósmico, crack! Saludos desde Argentina.
You are an actual life saver :)))) thank you very much for this tutorial
Thank you very much! It is very clear and helpful!
You are amazing brother u have a great mind , one of a kind
Thanks. Unfortunately this method seems to be excruciatingly long to work out especially if your string is like 6 to 7 symbols long.
Thank you man, i really appreciate the explanation
You helped me a lot , thanks
Thank you so much!
u really saved me..................i have a test tomorrow.............................thank uuuuuuuuuuuuuuuuuuu
thank you so much it's for my finals and i got everything so clear
fantastic
Thanks a lot, you saved my homework.
You explained it quite nice. Thank you...
So in the end we showed that w=baaba can be made starting from S or A or C?
Explained very well. Thanks
This was really useful. Thank you!
absolute legend
How can we read the parse tree from the table? Great video btw!
Only forgot to say how the string is accepted or not, the most important part
Thanku sir❤
Awesome explanation.. Thank you
Very helpful! Thank you!
Very cool, thank you
thank you so much my brother. but i think you should raise your voice and maybe a little bit more exciting. but still thank you, good luck
You skipped the hardest part, which is extracting the multiple parse trees that form a valid sentence
great explanation! huge thanks
so you can't derivate the string from the grammar if you don't reach S in the top most square?
Thank you 🙏🏻
Thank you, very clear explanation _:)
How many substrings of baaba are members of the given grammar ?
Thank you!
Thank you🥸🥰🥰
awesome

GOOD!!!
thank you very much sir.
Great video, thanks a lot!
Thank you, sir!
Very nice.
Hey do you know how can I have a sentences in the Chomsky normal form or something like that? btw thank you so much!
thank you so much!
I finally get it, cheers mate !
good work
