Mean Squared Error

Mean Squared Error When I call tf keras losses mean squared error y true y pred what I expect to see is that

Doing some research I see that with neg mean squared error we need to look for the smaller the better does it mean I have to look for the smallest value litterally which would be the first value in my graph or does it mean the smallest in terms of closest to 0 I have produced a linear data set and have used lm to fit a model to that dataset I am now trying to find the MSE using mse I know the formula for MSE but I m trying to use this function

For Mean Squared Residues MSR it should start firstly to know Least Squared Method in linear regression Simply put this method minimize the sum of squared difference between actual Y and estimated Y sum of squared residues SSr corresponding to Y Y 2 SSr divided by n 2 equals to MSR I m trying to made function that will calculate mean squared error from y true values and y pred predicted ones not using sklearn or other implementations I ll

From what I have read from the documentation it says that squared errors have the same units as of the response Is there any way to present the value of an RMSE in percentage For example to say this percent of the prediction is correct and this much wrong Def mean squared error y true y pred return K mean K square y pred y true axis 1 Here first y pred and y true are subtracted then that result is passed to K square which as expected returns the square of its parameter and then that result is given to K mean which computes the mean
