Thank you sir 😊

Very simple and best explanation, i paid lakhs and took a course, still was not able to understand. But your explanation excellent, understood very easily. Thank you 🙏

The example really crystallized the concept. Excellent explanation!

No one can teach like VARUN sir.

You have explained this topic in such a simplified way that i couldn't find in a course that i opted for. I was looking to understand econometrics but you have sorted this topic so well with such an unconventional approach. Thank you so much .The best teacher 😊

Kya sahi samjhaya sir apne 👍 best 🙌

bhai aap bhagwaan hain! please machine learning ki ye series continue rakhna aur agar ho sake to code example bhi dete rehna, aapka padhaya bohot acche se samajh me ata hai.

Too clear and made the concept very simple. Thank you for the video

Thankyou so much sir for this good explanation.Your teaching is really outstanding.

Machine 🤖 ko learn krwane se pehle khudke brain 🧠 ko toh learn krwalo 😂 nice quote sir. 0:30 Should be made a meme

Sir ji chak te fatte Siraa laata 🙏🙏

searched whole youtube for clear cut explanation of these models, no one literally no one explained as good as you

You are really very valuable for each and every one belongs to every genres❤ thank you 😊

What an explanation sir.....🙏 Really,maza aa gya

Amazing tutorial....helped a lot...thank you so much for this wonderful tutorial🥰😍😇

You are the best teacher in my engineering life !!!!! 🎉

Great explanation. Pretty easy with simple example. Thanks

Many thanks for making such a nice video in hindi . i have learned alot .

$ na bol ke Rs bolte to jyada samajh aata 😆 I was not expecting someone starting from basic. good job, thanks

This is the best explanation video after watching 4-5 videos before. 👍

Beautifully explained😊👍

Thank you sir for the amazing explanation

Thank you sir

Kon kon exam ke din washroom pe aake dekh raha hai ?🎉

when he said "phly khud k brain ko tw learn karwa lo" i felt it 😂

Sir can you please add a video of "MULTIPLE REGRESSION MODEL" to this playlist.

thanks for making this video.... I have ML exam thanks for explaining in simplier manner.

superb explanation of linear regression..

sir your explanation is very excellent thank u so much sir

You are a very good teacher

good explanation but more information could have been provided as to why we took mean, deviation, and product of deviation.

Varun boss zindagi asaan krdi aapne

Lajwab Sir❤❤

Very simple and clear❤

Under fitting aur Overfitting pr video bnaeye Sir

sir i have been studying ml for a long time but I want to understand what happening behind the scene sir thank you so much for this.this literally helpful to me.

well explained

Great teaching skills

Awesome sir

mind-blowing explanation

you are really great teacher ❤❤

Second..!!!😁🤩🥳💯🔥👍🏻👏🏻🫶🏻🤜🏻🤛🏻🤝🏻✊🏻👌🏻🤌🏻🔥🔥🔥

Hi bhaiya, bhaiya Ap aws ki playlist launch kro Ap bhot Acha explain krte ho bhot help milegi subscribers ko 👍

Sirrr you aree great 🙏

Sir is aging like a fine wine

Nice teaching skills sir

Example and last testing , prediction for x is so good

Super se bhi uper ❤

Thank you !

please double-check your definition of outliers. outliers are data points that deviate considerably from the average value of a group of statistics. Every point that deviates from the estimated fit line is not necessarily an outlier.

import numpy as np x = np.array([8, 10, 12]) y = np.array([10, 13, 16]) mean_x = np.mean(x) mean_y = np.mean(y) print(mean_x, mean_y) deviation_x = x - mean_x deviation_y = y - mean_y print(deviation_x) print(deviation_y) dev = deviation_x * deviation_y print(dev) sum_dev = np.sum(dev) print(sum_dev) m = sum_dev / np.sum(deviation_x**2) b = mean_y - (m * mean_x) print(m, b) def predict(x): return m * x + b print(predict(20))

Thank you sir for your great explanation :)

Top top guy!!

Linear regression is used to model the relationship between two variables, where one variable (the dependent variable) is predicted based on the other variable (the independent variable). The equation for linear regression is Y = mX + b, where Y is the dependent variable, X is the independent variable, m is the slope of the line, and b is the y-intercept. Key moments: 00:02 Linear regression is crucial for understanding machine learning concepts as mathematics forms the foundation, making it essential to grasp the relationship between variables for prediction purposes. -Importance of mathematics in machine learning concepts and its correlation explained. -Explanation of linear regression and the relationship between dependent and independent variables. -Collecting and cleaning data for predicting pizza prices using linear regression. 04:01 Understanding linear equations and the concept of dependent and independent variables is crucial in mathematical calculations. Linear regression involves calculating the values of dependent and independent variables for further analysis. -Calculation of dependent and independent variables in linear equations is foundational for mathematical analysis and modeling. -Exploring the concept of linear regression and its application in mathematical calculations for predictive modeling. -Visualizing data through graphs to understand the intersection of values and facilitate easier analysis and interpretation. 10:25 Understanding linear regression concepts involves refining and cleaning data to reduce errors, even though some errors may still occur due to outliers in the data. -Importance of data refinement in reducing errors and outliers in linear regression analysis. -Challenges of errors in linear regression due to outliers and the need for data cleaning for accurate predictions.

Thanku sir

indeed easiest explanation. Can you please explain cost function?

THANKYOU SO MUCH SIR🙏🙏

Here -2 means dilevery boy will give u 2 dollars 😂 Jokes apart sir teaching is best ❤

you are best sir ....

Thank You

great explaination

You deserve my sub.❤

Shouldn't we use point slope formula and calculus?

Sir lekin aapne Deviation(X) ko deviation(Y) se multiply q kiya?

sir this concept is also same in excel sir plz btado 😑

I am a commerce student. Regression is in my curriculum. I did not find any video which explained this topic clearly, suddenly I opened your video and you explained this topic clearly.😊😊

tq sir

Sir, X ka value zero to nehi liya apne. Aap mean of x = 10 li hae. Ye samajh nehi aya. 😓

sir formula mx+b hai but aapne minus kyun kiya end me

cant we just take square of y instead of product of deviations

Sir please create videos on Python Dashboard i.e Plotly & Dash.

7:46 Customer be like: Pizza to hai hi nahi. Paise ab tu mujhe de me nahi 😂😂

Sir ji unsupervised learning ki bhi video uploaded krdo

Sir aap padhate aacha ho bs gyan thoda kam chodo. Faltu batein jyada hoti hai content kam

Guru nandham

Good ❤❤

Respect from Pakistan

Sir mujhe 1 example batao regression ki Jo everyday life mejn use HOTA hooo

How the slope is equal to the division of sum of product of deviations and sum of square of deviations?? How slope becomes equal to it

Is it helpfull for premba

This was MIND BLOWING

sir multilinear regression mai yeah formula apply nahi ho raha hai

Sir g end hogya lots of love from Pakistan

Simple linear regression pr ek video mil skta h??

Sir iske aage ka course bhi pada dijiye

@sir can u explain all the algo with python code

❤❤❤

IS IT POSSIBLE TO CALCULATE THE VALUE OF M USING CALCULUS

sir full syllabus krado iska

Sir aap T-shirt ulta paheneho keya❓❓🙄

sir mujhe ye samajh nahi aaya agar 10 inches ka pizza hai to 13$ ka hoga or 20 inches ka pizza hai to 28$ ka kayse hoga. agar koi bta sakta hai to bta do yaar. mujhe ye samajh nahi aaya abhi tak. or ha mai ye nhi kah raha hun ke galat hai ye but bata do yaar kayse hua ye

sir deviation time minus sign nahi awega

Hello sir, I'm your student from LPU. anywhere I can connect with you?

sir plz upload the remaining videos ....... ;) 5 din bad exam ha

Msc statistics ka topic hae

Sir app ke playlist main 11th ka pura syllabus nikalta hain lakin 12th ka nhi 😢 kyun sir... App nhi padhayenge 12th walou ko... Plz sir padha dijiye plz

Hiiiiii

❤❤

arey love you sir, love from Pakistan.
