(Fisher information matrix) For a dataset \(\mathcal {D} = \{(\textbf{x}_i, y_i)\}_{i=1}^N\) and a model with parameters \(\theta \), where \(y_i\) is a continuous target variable, the Fisher information matrix (F) is given by the following: $$\begin{aligned} F_{ij...
A car with over 150,000 miles on the odometer needs an average of $5,000 of repair and maintenance per 25,000 miles traveled, according to Your Mechanic, a mobile-mechanic service provider. (Your Mechanicuses its (huge) dataset to figure out the average cost to repair thousands of differe...
