Показать описание
Learn what is Linear Regression Cost Function in Machine Learning and how it is used. Linear Regression Cost function in Machine Learning is "error" representation between actual value and model predictions.

To minimize the error, we need to minimize the Linear Regression Cost Function. Lesser the cost function, better the learning, more accurate will be the predictions.

That's great as I took a premium course from google.... I came here for revision, as I wonder if you could explain it in simpler terms.... Great explanation 👍

Dividing the cost function by 2 is not for finding the average. It is just for convenience when the squared function is differentiated, the nominator gets a 2 for multiplication factor. So to eliminate this we just put a 2 in the denominator, I suppose.

Hello, JP. You explained it really very well. Thank a lot.

Just have a query... why do we apply square for our cost function. is it really necessary?
