our meta training data set we can rewrite this loss function of performing a bag of evaluating predictions of a model as simply a loss function operating over the parameters Phi and the test data points so we're gonna write this right here and this this will be used mostly for convenience later on and then with this form we can write the full optimization problem as an optimization of the over the the parameters outputted by the neural network F theta and the test data set okay so now that we have this this optimization objective how do actually
