Luis Simply amazing. One small question? It is true that the linear regression line always passes through the mean of the data points. Why don't we start with the line which passes through the mean of the data points? In this case, we worry about only the slope and we can ignore y-intercept. Does it make any difference? Paul Manuel

@BharatSharma-ek8sb5 жыл бұрын
Thank you so much . I hope learning from you will make difference in my professional career. I have 2 questions. 1). When I initialize random line , I need to choose some initial numbers for slope and Y intercept . what is best practice for choosing these numbers. 2) using square trick , I need 2 coordinates to find vertical and horizontal distances. I have one coordinate from dataset (x1,y1) but how to find another one (x2,y2) (which i assume satisfies line equation?) .
@Han-ve8uh3 жыл бұрын
For vertical gap, the 2 points have same x. One y comes from the point, the other y comes from prediction from line by substituting into y=mx+b. For horizontal gap, the 2 points have same y. One x comes from the point, the other x is 0 since it's on the y axis.
@atinsood5 жыл бұрын
Luis, much appreciate this and making this so easy to understand. Few questions: 1. Does the line always need to be a straight line or can it be a curve(or is that the reason why it is called linear). 2. If so why/what implications is using a curved line also thanks for the hidden gem explaining beautifully why square error is called square error. 3. when doing the square error, why only consider the vertical distance, why not create squares using horizontal distances
@SerranoAcademy5 жыл бұрын
Thanks! A curved line can be used, for example, one with a polynomial equation (quadratic, cubic), instead of linear. This is called polynomial regression. One can also combine lines to make curved lines, and this is what neural networks do.
@Han-ve8uh3 жыл бұрын
Vertical distances have practical meanings. It's the gap between the predicted value and actual value we care about. In simple linear regression, vertical axis is output and horizontal axis is input. Intuitively, vertical gaps are more important to minimize than horizontal gaps.

In your first step, Do we take the random line? Or do we draw a line by doing average? How do I know whether a point is below or above to the line and left or right to the y-axis?
@davide82282 жыл бұрын
We just pick a random line. To see if a point is below or above.... it's only a math problem. It's very easy so instead of ask here try for yourself with pen and paper. Make a Cartesian plane and pick a point, writing its coordinates

@huojinchowdhury39333 жыл бұрын
I am little bit confused here Say, when first point say come closer it goes closer to it. Again when second point says come closer it goes towards it. If the third point is way more far from previous two point, then line will be go far way from first two points to be closer to third point. That means, data with more outlier, line will be never near maximum points but it will remain besides outliers. Is it something like while line moving towards a point, it will consider one point at a time? Or considers all other points towards which it moves already and the current point?
@Han-ve8uh3 жыл бұрын
This video is showing stochastic gradient descent where each update only considers 1 point. You can consider more than 1 point too (mini-batch GD) or even all the points in the data (GD), which is the most accurate way of updating weights and biases. The geometric interpretation he gives here is exactly the same as the usual gradient descent we see from other sources (just different by constant factors). If we want to consider more points, then the update for both slope and y-intercept will consider the mean of the current operations on vertical/horizontal gaps. Assuming the line updates by looking at points randomly, each point should get seen the same number of times and after many epochs of seeing all points (you can consider 1 epoch as seeing 1 point, or 1 epoch as seeing all points), the line should get better. The issue you mentioned of line not getting updated to a better position and always staying beside outliers should not happen unless the points you use to update the line are always the same outliers.

I'm wondering if dependency is not linear (but lets say, exponential or quadratic) does the solving non linear task would still be called linear regression?
@SerranoAcademy10 ай бұрын
Absolutely! That is called quadratic regression, or polynomial regression if the degree is higher. These models can also be trained in the same way as linear regression (by updating the weights using gradient descent). Note that the higher the degree of the polynomial, the better the fit, but the more prone you are to overfitting, so often when polynomial regression is used, one should also use something like regularization, to prevent overfitting.
