Learning the initializations
In this method, we try to learn optimal initial parameter values. What do we mean by that? Let's say we are a building a neural network to classify images. First, we initialize random weights, calculate loss, and minimize the loss through a gradient descent. So, we will find the optimal weights through gradient descent and minimize the loss. Instead of initializing the weights randomly, if can we initialize the weights with optimal values or close to optimal values, then we can attain the convergence faster and we can learn very quickly. We will see how exactly we can find these optimal initial weights with algorithms such as MAML, Reptile, and Meta-SGD in the upcoming chapters.
