Huber loss is a loss function used in robust regression, that is less sensitive to outliers in data than the squared loss. The function is defined as: L(x,y) = 0.5 * (y – x)^2 if y-x <= delta L(x,y) = delta * ( y-x – 0.5 * delta) otherwise The parameter delta controls how much influence outliers have on the total loss ... injector repair service
