This is a very good lecture. The discussion of the Loss Function is the first time I’ve see someone explain it so clearly and gives the intuition of what argmin really means
Having watched quite a lot regression videos I can say confidently this is something which sums up and condenses each and every thing for a beginner to grasp linear regression smoothly(see what I did there?). Thank you so much for making this public!
This lecture was so well explained! The baby-steps approach is so clever. By understanding the simplest cases one can grow from there! Thank you Dmitry!

Thanks so much! The simple introduction makes all the generalized equations a lot easier to understand!
Do you have the link to the course?
This whole channel is amazing. Thank you so much
Wonderful explanations! Make a hard subject appears simple.

is there any website of this course? can we access the notebooks?
Отличное объяснение! Спасибо ❤
Hello , are the slides for the videos lectures available . I know the slides for other courses in the series are available but not this one ?
Great lecture :)
i want to ask something about the course...there are many courses related to ML on this channel but where to start....what is the 1st course that i pick???anybody please tell me
1) Basics of ML
2) Basics of Maths (Statistics)
3) Python Basics
@@tilakkalyan there are some courses on this channel like:
Probalistic ML
Statistical ML
Math for ML
Intro to ML
and many more related to ML but i want to ask that from these all course what should be the 1st one to learn...
Good 👍
machine learning vs pattern recognition?
beta_1 = ((1-n).Sum(y_i.x_i))/(n.Sum(x_i^2) - Sum(x_i)^2), beta_0 =(-Sum(y_i) - Sum(x_i).beta_1)/n. Did someone solve the exercise in the end.
thank you
great lecture!! 29:00 I think you increase beta to decrease the loss since the derivative is negative
It's true but this equation is true for increases beta or decrease it's depends on the signal slope of the curve of MSE
