Um, what am i looking at?
This is a simple linear regression which tries to fit the best possible line from the given data points.
Just tap on the grid(Data Space) to add a new data points ( you can also drag the data points by click and drag), play with the controls on the right and hit recalculate!
Epoch: for how long should we run the gradient descent iteraction.
Learning rate: how much we scale our gradient at each time step to correct our model.
But, What is Linear Regression?
The goal of this method is to determine the linear model that minimizes the sum of the squared errors between the observations in a dataset and those predicted by the model.
