"Relationships are like Algebra, you look at your X and Wonder Y"... damn man 😂😂😂

[@SirajRaval]

;)))

[@avinasha3603]

:D

[@felinetech9215]

Yeah literally, it was dope !

[@aevai]

Your videos are amazing! They remind me of the quote "anyone who tries to make a distinction between education and entertainment doesn't know the first thing about either"

[@SirajRaval]

thanks Jonathon! Reminds me of Disney, one of my main inspirations

[@DigitalMonsters]

I understood a couple of those words.

[@AkarshSundareswar]

Izumi Koushiro you need more epochs then..

[@SirajRaval]

Epic! Keep watching, concepts will be reinforced over time

[@younisibrahim4562]

Damn the way you've moved from Scalar-to-Vector by Algebra-to-Linear algebra, so Array-to-Matrix. You're a professional Educator, Siraj. Thank you very much.

[@aidangomez4726]

GREAT visuals and production and perfect explanation. you just keep getting better at this.

[@SirajRaval]

thanks Aidan for following my progress

[@aidangomez4726]

Siraj Raval 🅱️🅱️🅱️🅱️🅱️🅱️

[@adoniyasgirma4104]

Great video siraj!your videos aren't just informative but entertaining as well, keep making them. big fan here

[@pinkiethesmilingcat2862]

SIRAJ, i finished the Spanish subs in the video of the Intro, maybe i'll make the next tomorrow or today at the night. Please, accept it and update the Google Drive Document with the script of this video when you can (: Awesome vid bro!

[@SirajRaval]

Gracias Pinkie, i've accepted your subtitles. I've also added this script to that same document. I will continue adding every weeks script to that document and review any subtitle submissions you make. :)

[@nands4410]

Not all heroes were capes

[@pekhotinyets]

I have to watch this twice. Once for the math and the other for the humor

[@kingarthurthethirdthst3804]

What you explained: 11 minutes of precious and resourceful information What I got: :O + :P = 69

[@vickylance]

I feel you Bro... I feel you........

[@BitcoinmeetupsOrg123]

Loved this video. Very interesting subject. It reminds me of stuff I have been thinking about myself independently for years. Thank you Siraj, this video was great.

[@SirajRaval]

dope np

[@riganpatel]

this is an awesome explanation of math we have learned in college thanks Siraj god bless

[@piotrvandrey853]

I have to watch Siraj's videos several different times. Not to grasp concepts, but becuz I'm usually laughing the first couple of times thru

[@piotrvandrey853]

let me also add, the more I go thru his mathematics videos the more I despise my past mathematics teacher. I flunked highschool algebra, yet now I find myself using linear algebra to optimize learning programs. Thank You for the teaching, Siraj.

[@SirajRaval]

dope haha

[@alemmat1750]

very good videos Siraj you are the best

[@c.s.bahushruth5368]

Wow I'm early Hey Siraj could you do a video on quantum computation please please please. Also ur videos are Boss ur a Boss.

[@c.s.bahushruth5368]

Just the basics of it. Why quantum computing? And perhaps an explanation of a simple code.

[@aidangomez4726]

C.S.Bahushruth you don't write code for a quantum computer yet

[@SirajRaval]

thanks! hmm. after this series i will consider it

[@Zzznmop]

this channel is my safe place.

[@SirajRaval]

im honored and will keep it that way

[@glautermoulin]

Amazing explanation ! Congratulations

[@larryteslaspacexboringlawr739]

thank you for math and intelligence video

[@ПетрИванович-л6ж]

it is great keep making videos!!!

[@prasenjitgiri919]

Thank you for the explanation, but one thing I'm still not clear on is how does Word2Vec finds similar words from sentences. For eg. 1. Mercedes is a German legacy 2. Honda on the other hand is pretty new 3. But nothing beats Toyota reliability In this context, how will Word2Vec get to cluster {Mercedes, Honda, Toyota} as one group - can you please help explain this. I do get calculating distance, vectorizing the position of each word and selecting the dimension randomly but how does Word2Vec works. Thank you again Siraj from a software developer.

[@hanyuliangchina]

vectors into tesla, i like, you are great.

[@SirajRaval]

thanks Tony

[@iLoveTurtlesHaha]

Hey, I find your memes to be distracting. The one with spongbob at :50 didn't really carry the point you were making. Don't get me wrong, I love that you use memes, but I feel they should be included only to solidify the point rather than a quick joke - or after your point is made so it's not distracting.

[@frankbraker]

This video is hilarious! Also, wow.

[@kondziossj3]

don't forget add this film to your playlist :) btw... you are great! :D

[@SirajRaval]

thx just did

[@anismatar]

Excellent but maybe if this was broken into 2 vids of 10 mins each lots of concepts would be more clearly explained.

[@anniamartinez7819]

so cool your video!

[@gaieepo.jeffrey]

Although it's just one word, I can see your Chinese mandarin pronunciation is quite good. :)

[@SirajRaval]

+Gai Wang Xie xie

[@paulntalo1425]

Thank you for the video

[@codigo_logo]

I recommend gensim for word2vectors and numpy to make some operations, gensim it's just great for word2vector guys, really it's awesome.

[@islomkayumov4552]

"Love you too" -Elon Musk Lol

[@Kingstanding23]

I thought I knew what vectors were until I watched this! Twitter @dommckean

[@madeyeize]

Hey Siraj, please consider making a video on Object detection, the deep learning approach perharps with Fast-RCNN, YOLO, SSD or The tensorflow object detection API..please....

[@7m43]

7:30 xD Oh, My God, I love your videos

[@jaroslavzukov2719]

AHAHAH fuck, I'm dying, you're so funny 😂😂😂 Right now I'm doing ANN course on Brilliant and you're videos are super helpful, thanks a lot!

[@konstantinburlachenko2843]

Zero norm at 08:59 is not a norm. Never was be, never will be. Some people which work in convex optimization called it caridnality. At lease because card([1 0]) = 1, but card(2*[1 0]) is also 1. It is not 2.

[@AjayKumar-qm5fu]

Died laughing at 5:56 😂😂😂

[@konstantinburlachenko2843]

09:54 - I think it false description in that sense that you're overfit and etc. what is real going on you solve bicreterion optimization problem. For more details what is regularization please take a look into convex optimization books, such as this web.stanford.edu/~boyd/cvxbook/ p.s. Thanks for video! It is still great!

[@akashpinnaka3254]

Is the Interview with Elon musk happened or the bit shown in the video is a made up? I couldn't find any result in search. If it is real, someone please send the link. Thanks :))

[@MrKaryerist]

Brilliant demo of how vectors can be used in real life. Helps me to put it in the context of my linear algebra course👍

[@yoloswag6242]

As a high performing Autist, it's very difficult to absorb your Humor. Danke

[@WTFJapanTV]

I died laughing at I see vectors

[@spandanhetfield]

Would be great to see someone actually point out the mistakes in this video. I begin by pointing out 5:31. By reshaping your input you don't take it to a new vector space. An mXn dimensional vector space and a 1Xmn vector space are homeomorphic. Anyone want to add to this list?

[@spandanhetfield]

Adding on as I watch, 6:00 word2vec was not a single neural net. It was an ensemble of models. And no it can't learn the embedding for a new word. There's no training/testing split there. There's only an embedding.

[@marcoflagg6601]

thank you so much for this video. :)

[@UnboxingSve]

Great Siraj. Keep it up.

[@nickellis1553]

Checkout Siraj's new series of mixtapes: The Math of Intelligence The Math of Intelligence 2 The Math of Intelligence 3

[@SirajRaval]

u know what it is, my courses are like albums

[@paulwillisorg]

Unfortunately I can't watch these videos with my 13 year old daughter because you keep saying F*#K!!!!!!!!!!!!

[@SirajRaval]

hmm. interesting point Paul. I will keep the F word out since i am trying to reach kids. thanks

[@RAJATTHEPAGAL]

i think they get it ya we got it moving onto ...... 😂😂😂

[@MrJEstacado]

3:10-3:30 cracks me up

[@naveenvarshney7886]

great video...please make more videos on maths...since it's the essence of machine learning..

[@SirajRaval]

u got it

[@PratikGujral]

That's too much of information to digest at once.

[@YahiaDesigner]

What is the source of your memes?

[@mralexbiz3936]

@AskAlexBiz: @sirajraval I love you man!! You really are a true inspiration!!! P.S. lets change the " $40 Billion industry" Check your GMAIL - from Mr Alex GF

[@SirajRaval]

thank you, love you too, and too busy to collab rn

[@mralexbiz3936]

+Siraj Raval I totally get it! Can I ask you if you know anybody with BLOCKCHAIN programming skills??? I will very much appreciate it Siraj!!!! Peace!

[@Paujujiya]

what horoscope are you?

[@SirajRaval]

[@sehbanomer8151]

You pronounce Beijing perfectly

[@puligesi546]

Is there anyone else who heard gibberish?

[@luis96xd]

This video was so amazing! It was well explained, thanks Siraj! :D

[@mrcrash4974]

So how does matrix multiplication work programmaticly in numpy? I thought matrix multiplication is done the algebraic way in a loop like you showed in the algebra example and numpy is just faster because its doing its looping calculations in C. (4:52)

[@SirajRaval]

will explain this in-depth next week promise

[@simetry6477]

Crap you are convincing me to take the two vector calculus courses at my college. In addition to the multivariable course. Okay so which foundational papers in the field should I read and which major books for class, for amateurs and professionals.

[@simetry6477]

Off to math on Reddit, Quara, and mathexchange forums.

[@PrashadDey]

So, what is vector exactly?

[@konstantinburlachenko2843]

Please help, I don't understand what is tensor. Vector is invariant under coordinate system. I can use no coordinate system at all e.g. for moving particle under the known curve - I can measure the path length. Q1: Is tensor depend on coordinate system? Q2: I have rather good example of tensor of second order like intertia tensor of rigid body. I can use it to "exchange" non-free rotation vector "w" which I can move along a line into momemt of impulse(kinetic moment) via L=IW via using using usual rules of mulitplication. But what does it mean to be a more high dimensional tensor like 3? In video it have been said that this just an array of numbers but to which ojects I can apply this imagine tensor of degree 3 and how I should do it? How this numbers which are represented a tensor changes if use other coordinate system to describe my objects? Thanks

[@valcho]

Too many memes, which distract from the core topic of the video. While I appreciate your deep knowledge into the meme ecology and your grasp of the matter, I'd prefer them to be less in the future.

[@SirajRaval]

thanks for the feedback

[@alexmorrison4140]

Hey Siraj Raval, how probable is it for abstract machine learning libraries to reduce demand for machine learning expertise to the point that the average person could not reasonably expect to gain employment in machine learning after investing the considerable effort it takes to understand the underlining math of machine learning? For example in a previous video you showed a abstraction of tensorflow that allowed you to simply take a labeled data set f(Vi) = Yi. All training/learning was then abstracted by the library and and you simply input a new vector that was not labeled and and the library output its best guess of y's value or label based upon the data set you feed it. Will machine learning EXPERTISE only be necessary for companies that develop machine learning libraries? How long is the window for wide demand, not counting grandiose entrepreneurial endeavors?

[@jasneetsingh4018]

projects for combination of machine learning and cybersecurity

[@SirajRaval]

k means clustering fraud detection

[@jasneetsingh4018]

Siraj Raval how can i build a machine learning model for blocking the attacks made by hackers.and how would be the combination of block chain and machine learning...n thanks for reply

[@NikhilKumarM]

Marco Ascensio is pretty smart.

[@LogOfOne]

great vid

[@swapanjain892]

Videos are great.Just try to keep the videos in the order!!

[@SirajRaval]

Thanks! Also I will happily review any PRs to my syllabus if someone finds that the order could be made better. github.com/llSourcell/The_Math_of_Intelligence

[@ConTejasMusic]

Awesome vid Siraj. One question - at 8:56 when you show the 4 types of norms, is there a norm that you recommend developers should use most often? Or does it depend on the type of ML model you're building?

[@onefulltimeequivalent1230]

How do you cross a mountain climber and a mosquito? Not at all, because it doesn't work with scalars and vectors.

[@frenchpet]

tfw no qt ai gf

[@sandtiwa]

I wonder where you learn you materials from. Research papers? Anyways, thanks for your videos.

[@nano7586]

Vectors are pretty much the major problem I'm facing with ANNs right now.. thanks for that video!

[@yamaaoh9511]

hi can you answer this for me sir? 😶 " given the line x+3y+5=0 and a circle x^2+y^2-6x-4y+3=0 find the equation of the tangent to the circle which are parallel."

[@munkh-odjargalsaikhan258]

you speak mandarin?

[@nagendrenkrishnamoorthy195]

Hi, I have a general query. Which algorithm is good to detect anomaly neural network or multi variable linear method ?

[@YAakash]

awesome is less for this video :D where can i find that matrix multiplication visual tool at 4:37and... you can't divide matrices :P

[@JordanShackelford]

I literally just googled using non-numerical inputs in a neural network last night

[@SirajRaval]

i read ur mind

[@grantking2880]

I really enjoyed the interpretive hand dance tensor music break.

[@SirajRaval]

thanks for saying that. i'll do more soon

[@ericsparkman1303]

awesome edutainment

Awesome man.., (y)

[@TheWhyme01]

Siraj ur my nigga!

[@colox97]

i've just done the exam in linear algebra and i find it here? no thanks (even if your video was much more spicy than my entire course)

[@anteconfig5391]

whoa, you said "also useful for preventing overfitting" and I realized I needed to take notes. I'm glad I stumbled upon your youtube videos sir.

[@akshaypratap2010]

Too complex

[@thehelper9975]

I like it

[@2parinda]

Brother your descriptions are really really great!! keep it up.. Congrats

[@robinranabhat3125]

no matter what people say about your fast paced teaching , i am in love with your style .

[@rajdeeppurkayastha3287]

can we implement tensor concept in java ? I am asking because Java includes "Vector class".

[@guitarheroprince123]

WOAH. I didn't expect you to understand Einstein Field Equations! Dammit you gotta do a series on them too :3. You inspire me Siraj. You really really inspire me to keep learning. Thank you for existing.

[@SirajRaval]

thats my man keep it up

[@guitarheroprince123]

Siraj Raval Thank you man.

[@kaziboy264]

Just found Welch Labs on youtube as another spot for good youtube videos on introducing ml, you guys should collab

[@kishoregeorge1129]

Best explanation of 'word embedding'! Superb video!!

[@Jawis32]

5:00 why do you compare their number of operations, when they aren't even the same thing?

[@nitinbhandari7932]

Did I just witness the best analogy for fit and overfit? Darn!

[@roshan_singh5709]

Vector is an array of 1-dimension, can pls elaborate this statement, I didn't get it?
