Regular Languages: Deterministic Finite Automaton (DFA)

[@andrempmorais]

I learned in 6 minutes what they were trying to teach me in a 2 hours class in college, thank you!

[@hrmnish]

your voice is so calming, it makes me want to learn more. Very well-paced video. Thanks a lot this channel definitely deserves more viewers.

[@cyrusdavidpastelero9920]

You deserve more views and subscribers! Thank you! There is a mistake at 4:55, when q1 is false or 0, it must go back to q0.

[@seancarlopiodo2685]

thank dude, I also noticed that 😅

[@timwhite7127]

Oh man, thank you...I thought it was something I couldn't figure out...Now I can go dig my CS books out of the trash.

[@Shelly-kx2wz]

Now this video is criminally underrated. I never used to attend the classes in my university as I would find it so boring as my pprofessor would go on and on. But you caught my attention. And Thank you for that.

[@lokeshnn5389]

I feel that knowing "where" something is used, matters a lot when learning. None of my teachers told me "where" FA is used. Great video and thanks for letting me know!

[@kehinde.abiodun]

I started my master's degree program in IT about two weeks ago and I was hit with this concept on the first class, then my head kept spinning infinitely until I found this video. This has made my life so easy. Thank you so much.

[@billy-cg1qq]

This girl dropped the most amazing video series on Computation Theory and then disappeared! Respect to this amazing girl!!

[@theprostratior1345]

Thanks for keeping this thing short and crispy 👍🏻 Please keep doing this

[@deckarep]

This was a fantastic overview and beautifully presented!

[@ryanliu93]

I appreciate your video. Your visuals are adorable and help me easily understand the concepts. But I think there's a little bit of confusion at delta function, q1 back to q0 when it read 0

[@HasanZobaer]

This is the best video I've watched on Regular Languages and Deterministic Finite Automata DFA. I don't usually comment but this video is sooooooo goood! I am honestly out of words but wanted to leave a comment mentioning that. Been studying these for an entire course but was having so much trouble understanding in class. This video explained it better than 10 lecture classes no cap

[@harrisonakunne5119]

This video describes the topic with much clarity, definitely deserves a lot more credit.

[@mustapharaimilawal8053]

Wow, your video just simplified a very complicated subject, nobody has ever made DFA so understandable, please do more. Thanks a lot.

[@siddharthlaiju4497]

Can easily learn topics by spending much less time, thank you for this. You deserve to be paid better than most of the university professors. PLEASE KEEP IT COMING ABEG.

[@hyperboliq]

Abeg 😂

[@張余智]

Thank you for this familiar and cute video, it helps me a lot on my computer science course. Thanks again.

[@mikemalachy]

Extremely concise & clear for anyone to understand.

[@zackcarl7861]

It's the best 6min revision ever , if you already studied toc this is extremely helpful

[@ahmedsalman3294]

This is just WOW. I wish you were my teacher. One of the best content with a brilliant way of explaining things. 👏👏

[@edwardcullen1739]

Refreshing my knowledge after *ahem* "some time since I did my undergraduate degree". An excellent overview! One minor point: DFA is "Deterministic Finite-state Automata". They are a type of "state machine", so the "state" part is important and anyone new to the topic should be aware of this.

[@lawalsamuel4609]

Geeezzz!!!! I can't believe I didn't begin learning this topic with your video!😩.....such simplicity and specificity

[@fjpicazo]

Such a great video. DFA's always seemed so abstract and now I understand everything a lot better. Thank you!!

[@staz8671]

Why did I not see this channel yesterday. Succinct presentations. I really appreciate this. Thank you

[@aikasal5214]

My dear, You just did it great. I can't describe in words how this video made it easy and how happy I am. Thank you

[@evergreendon6469]

the best explanation of DFA I have ever seen, absolutely fantastic ~!

[@theworstrycha]

great video! you explained a concept in my second language and it was much easier to understand than at my uni:)

[@hugoirwanto9905]

Your explanation is amazing. This channel is so UNDERRATED!

[@thoyo]

You made this incredibly easier to learn. Thank you!

[@VahiMangai]

Wow alright. This is as adorable as it is informative. Thank you kindly for your work and skill.

[@cherryberry6922]

better than an entire semesters worth of lectures!!! God bless

[@Nikhil90able]

This video is so helpful. You explained everything so well and in a very simple way. I was having a hard time learning it from the textbook. Keep making these videos. Amazing work.

[@memorix101]

This is so well made! I hope you can find the time to make more of these videos. 🙂

[@MapleKollaLK]

i watched a 1 hr theory lecture and didnt understand anything . Watched her explaination for 7 min and Boom Gottcha! Thanks and keep doing the good work

[@edu-say-fun]

Amazing explanation in the easiest way. I had trouble in learning these concepts, but your videos saved the day

[@prerit791]

Thank you a lot for putting so much efforts into making this video. It was quite helpful for me. Keep doing this thing

[@Dudley3882]

Best explanation on the whole web!! Thanks!

[@ajmalnajath1399]

this channel is underrated AF. keep going girl

[@winkihuang6253]

this is amazing, we would love to watch more of your video

[@cloudjumper725]

Perfect. It's almost 4AM, Final exam is in a few hours and looks like I'll be able to pull that academic comeback. It's funny how free material available online is times better structured and explained than 90% (and, unfortunately, it's an exaggeration) of materials from our lecturers. Thank you.

[@himalbhandari1798]

how did it go ?

[@potatolegs3505]

needed to learn what finite automata were before a class and this was so easy to understand, thank you very much!

[@hugojj101]

Thank you, don’t think I could have asked for more well explained and sensory appealing information on this topic. :)

[@saikatdas5474]

That was a really good example. Thank you for clearing the concept.

[@glinspire1103]

This is really amazing explanation with simple but expressive example. Thank you!

[@mariaandreamartinez6613]

Thank you! So good explained. I loved your video and the tone of your voice. You took all my anxiety away

[@bobbrysonn]

You made it easy to grasp the idea of dfa. Thank you.

[@trevosh15]

This really helped this click for me! I was having a lot of trouble understanding this until I saw this video.

[@tumuramyepedson875]

one real practical appllication of automata to explain the question

[@ovo5744]

i love the way you explained DFA. beautiful presentation!!

[@hostelprofessional573]

These are really great videos. This young lady has a gift.

[@aahil_dev5572]

Thank you , quality of this video is damn high , very clear explanation

[@cxrxmeluxe]

Earlier today i had no idea what my lecturer was explaining and felt like it was a complex concept but your video really lit a bulb in my head. Thank you 🫡

[@kid_kulafu_1727]

O shit! You had this. Bless you. I just commented on the other video to make this topic. Coooooool!!

[@kid_kulafu_1727]

We this in our checkout process at work. Cart -> address -> payment

[@ST-wm5ey]

This was helpful. Thank you. Deserves more subs and views honestly.

[@KingZoroark]

This is actually really cool and super helpful for my college course 🤗

[@yusufsabr2288]

I wonder if this kind of explanation is harder than our professor does... Our professor explained this lesson for 50 minutes and i could not understand. But i understand same topic in 6 minutes. Crazy.. thanks!

[@dorissorana]

This was so good, your voice is so soothing, forgot I was studying

[@Abhi00111]

explained so well with some real life relatable example its amazing keep up the good work.

[@xXSantsXx]

Very well done. Simple, illustrative, and enjoyable. I’m definitely using this to study. Thanks

[@igorying8548]

Clear and concise ! Quite understandable even for me! Thanks!

[@aliyyah82]

Clear and concise explanation - great video!

[@nuton9706]

You make it so clear and easy to understand Thank you so much!!

[@ELKADUSUNhalifesi]

*Correction for table at 4:54 : "When state q1 reads 0 it transitions to q0 not to itself"

[@RudranarayanaSabat]

thank you ma'am . your voice and teaching is so beautiful .

[@StevosSows]

amazing video ur better than 20 textbooks combined im sure

[@Mahlodi_Makobe]

you literally saved my semester! Thank you

[@markfaiziuni]

Wow this video is amazing!!! very helpful to understand DFAs! thank you so much!

[@debarchanbasu1962]

This is so crisp. Thanks Lydia ❤️

[@Kniffel101]

These illustration help so much in understanding the concepts! Thank you SO much! =O

[@Isichernit]

Best explaination so far, a shame you have so few views!

[@XuYe-c8m]

Thank you so much for this video. It taught me so much. However, at 5:00, for the table, when q1 has a 0, should it go back to q0 instead of staying at q1?

[@comps_77_manishnayak5]

This is super simple thanks lydia. amazing work thanks again.

[@GoatMen]

Finally someone made this video in clear English!

[@asmifti9147]

Awesome explanation and animation, thank you!

[@pacotaco1246]

Omg this is so helpful u need and deserve so many more subs ahhhhh

[@shashankgsharma]

Good explanation. Understood the concept thoroughly!

[@adityasailada3398]

Awesome...this channel will blow up soon

[@shahadsaleh7679]

AMAZING presentation! 😍

[@gloverelaxis]

this is perfectly paced and explained; thank you so much

[@DachiZedginidze-ds8ku]

I think there might be a small issue in transition function. q1 transitions to q0 if 0.

[@yumis_cells]

so easy to understand, thank you! hope you will make more videos again some time :))

[@aliyyah82]

Aww this video is so motivating 😭Love your videos!

[@easyexamcare3222]

I m from india... your example too good ... continue your creation of animated videos ... all the best for your channel 👍👍👍

[@juanpunch8473]

daym, you made it very easyy for me to understand, thanks

[@aymansoliman1783]

Did this lady just explain the 45 mins. lecture I've been studying?!

[@MindbendingRobot]

@Lydia Cheah at 2:45 why don't we say heatwave is over when q2 drops below 45*C? Is that just not apart of our language? What is missing from our definition that we did not consider heatwave over?

[@Isichernit]

By the way, I think you made a mistake at 4:58 q1 should go back to q0 when it gets a 0, not stay in q1

[@MindbendingRobot]

She stated at 2:45 that when we drop below 45, we don't go anywhere, we just stay at q2 because we already triggered the heatwave definition. The concern I have is that with her explanation, we never leave heatwave. But intuitively, what you said is right, if we drop below 45, i.e. 0, then it seems that we should return to q0.

[@fedoralaura3643]

@@MindbendingRobot you're thinking of if q2 is zero, but if q1 is zero we return the the first state since at that point we've only had one consecutive day above 45 degrees

[@farwahbatool6247]

Yes, q1 on input 0 goes back to q0.

[@luretto956]

The automaton tells you if a heatwave has occurred. After one has occurred it doesn't matter what happens next. We just stay in the accepting state. What you say is true in the case that we want to know if we're in a heatwave right now.

[@Neos4398]

lydia you are a genius and you explain perfectly! please come back to youtube

[@pranavkale3289]

clear and fantastic explanation. Thank you.

thank you for the short n informative vid

[@agentstepheng289]

@4:58 Why doesn't q2 go back to q0? If after two days, the temp drops to
