if someone like myself is thinking how to find the value of k, so here it is: K should be the square root of n (number of data points in the training dataset). K should be chosen as the odd so that there are no ties. If the square root is even, then add or subtract 1 to it.
Thank you very much Sir! i am a student of you but still saying Sirji aapke method of Teaching mein Quality, Effectiveness aur Time Efficiency teeno hai. Aapke Efforts ke liye bahot bahot Dhanyavad.
This is good. Can you tell me how to calculate distance if the indicator variables are numerical and categorical. For e.g P1={4,6,f,8,v} & P2={8,2,y,7,p}
You need to convert all those categories into numbers like if you have 3 categories v,p,y so it will be converted into 0,1,2. So all the v's in data will get converted to 0, p's to 1 and so on 🤟
Love the pace of your videos, I was finally able to watch a video in which the instructor maintained his pace and I could skip through and understand everything
I have few questions 1. Why did you take k=3 2. Why wasn't 3.16 considered nearest to 3 3. Had we set k=2 and result as 1 Fail and 1 Pass, what would have been the conclusion?
1. K is the number of nearest neighbours that have to be acknowledged. K is provided in the question usually. 2. 3 is not the comparison value. That is just the number of neighbours you have to figure out. you have to compare the values to zero. Consider x to be on the origin and you are figuring out the distances of it's nearest neighbours. 3. k=2 here will give two pass. If it was one pass and one fail then you would have to consider one more neighbour to give you some probable answer.
@@019_deepdas2 That just means the question didn't choose an appropriate value of k. It will have to be adjusted to include less or more neighbors to consider. I don't think an exam would include such a question unless they want you to explain what should be done to remedy this.
important observation 1. if k is not given in the question , always take k as a odd number to avoid tie. 2. for guessing take square root of n , and if it comes out to be a even number , then add or subtract +1 .
5:33 Correction: The point is in fact the farthest from x. We are not comparing the distances with k, it just represents the number of nearest points we will consider. We are actually comparing the distance with 0, the smaller the distance the closer it is to 0 and the nearer it is to x! Great video nonetheless!
3 is not the comparison value. That is just the number of neighbours you have to figure out. you have to compare the values to zero. Consider x to be on the origin and you are figuring out the distances of it's nearest neighbours.
I have a question, can we consider any random number for 'x' provided in the dataset? For Math and CS? Or is there is any calculation behind the X of Math and CS?
Your all videos in ML are good. For this particular one you have not explain that to have decision we must always K as ODD number and how to arrive at best K value , also what if the label is numeric instead of boolean.
We use odd values for k just to avoid tie situation and there is no hard & fast rule for finding value of k and it can be taken experimentally. Few methods are there like elbow method etc
Because of your videos, my professor said: 7:11. Thank you so much!
hahahha Good
gooood
Nice one!👍
Hahahhahahahhaha...😆😆
Hillarious ...

Thank u so much sir...aap wo concept 5 min clear krdete ho jo hamare teachers pure semester me nhi kr pate
Sir , Great explanation , thanks a lot , am having zero knowledge on this,but learnt because of you
thought my 2nd name was complicated to spell
Brother Thank you so much ! All concepts cleared
You are such a good explanator! Very well explained
sir you're a gem, thankyou for the easiest and detailed explanations!
It was really very helpful for me. Your way of teaching is really very good.
Hi , angel Priya
Hey fake girl
The bestest channel for last minute preparations in machine learning 💯💯💯
Has anyone noticed that we can directly conclude pass from the second row of the given data :D BTW Nice explanation
yes we can conclude from the 2nd row but if data set is large then difficult to conclude.Thanks
No we can't because we need to see CS marks too
@@alphagamma7662 its 8 more than 7, so technically he is passed 🤟😂
But it is not for us.
It is for computer?
Is it computer has brain like you?
Thanku sir we are very fortunate to have this TH-cam channel as well as your way of teaching and skills got to you
Sir, this is high quality stuff.
Thank you , very very much.
मैंने कितना वीडियो देखा पर यह सबसे अच्छा हैं.
Please also tell how to choose or select "K".
thank you so much for creating such videos i am passing my exams just because of you god bless

kal meri machine learning ki exam hai or aaj mevideos dekh rhi apke it helpss alot sir thank you so much!!!!!
Pass ho gya?
Thank you very much i cleared many topics because of you .hope my exam goes well.
Congratulations Bhai Pass hogaya, ab mai bhi yeh vimdeo dekh ke paas ho jaunga 😼
best channel to study at last night ....Thank you !!
guys dont waste your time on youtube , just watch this video , best video on whole youtube
wah..keya simple explanation sir...aap kamal kah teacher ho
You are more than a teacher , a magicial ,,, thank you so much sir

k should be taken as odd number only
kdk explaination sir.....Its really the 5 minute engineering.....
Thank you so much Sir, it's my best channel ever😇
Really helpful for exam preparation within a short span of time ,thank u for ur effort sir🤩🤩🤩
Zabr10 Explanation is real good
I am very happy sir
This topic very help my final exam

Easiest explanation ever.
7:45 kr diya sir.....
Awesome explanation.....very simple and easy yet effective.....great job...:)
Sir, you explained the whole concept in an easy way. Thank you so much!
Thanks for this video......your teaching method is toooooo good please give also another example of this point
Tomorrow is my exam and your short Video are really helpful ❤
Finally I got it after coming from the previous semester.
Thanks sir paper aacha gaya aapki vagase!!!!🙏🙏🙏
such a good explanation, Thank you so much!!
Super this is how you teach no jargons; thanks
Awesome explaination of algo in short time, great video sir!!👍
Kya teacher hai 🙌🏼
You are Just brilliant!!! Amazing explanation
Its very Cleared and in short thanks a lot
Greate sir learn so much within less tjme
wow, it's like you gotta kidding with me, jsy sir g ap ny hr chz explain ki mza a gya, thanks a lot sir
Very nice way of teaching sir!!
bhai bhot mast short and sweet explain kiyay....
Very nice explanation. Thank you!
u explained very well sir , thank you so much !
Very well explained. Thank You :)
Thank you so much for save my time sir
Great teaching Sir Ji, keep it up & GOD blessed Uhhh😃👌✌🤟👍👏
Excellent explaination. thank you sir🙏🙏
Excellent sir. Please also make practical with python..............
sir bahot acche padathe he ....video chota banane ke liya app chota solving part skip kare to be achha hoga
Bhai case based reasoning par big bana de ek video......exam hai pls
hi brother. good videos, could you make a video explaining svm ?
extremely good teaching
Very well explained. 😊
Thankyou
Wow! Amazing explanation!
aghr duno yes ho jain or duno no to kon saw choose krain jaisy k ki value 4 h to tie a jay to kya krian gay
Another awesome video...Thanks
What if the Pass Probability = Fail Probability ?
Go for anyone
That is the reason we should take k an odd number, so that you'll never endup getting a tie
@@vivektomar4208 that would be a biased result
very well explained thank you sir
hamare coaching centre vale sir aapke videos dekte aur hume padate hain, aapke example ka screenshot lete hain aur itne ache se explain tak nahi kiya.
Very nice and clear explanation, thank you so much Sir.
Sir u are dam amazing trust me.. the way u explain topics in so amazing and wonderful..🔥🔥🔥🌟⭐
Clearly Explanation....
I have a question, can we consider any random number for 'x' provided in the dataset? For Math and CS?
Or is there is any calculation behind the X of Math and CS?
Can anybody explain that how the actual algorithm works becoz everyone teachs about problems but not on algorithms😑
😂😂
Sir your Vedio was fantastic
Thank you Brother!! Are u mechanical Engg. Background?
7:57 mins worth it :)
😇😇😇 NICE EXPLAINATION
Very good explanation.
Thanks u sir... Also make videos on Theory of computation...
Thank you so much sir for your assistance..

We likes your all videos... We require haversine algorithm with simple example.. Please request you to make it for us..
you save my day
what if k is equal to 4 and we get 2 pass and 2 fail from euclidean distance
You are the best.
you are the BEST SIR
Awesome explanation thanks alot sir! 👌
Awesome explanation keep it up
thanks for saving time.
