Cocalc Optimizer And Backpropagation Ipynb
Training a neural network consists of modifying the network’s parameters to minimize the cost function on the training set. In principle, any kind of optimization algorithm could be used. In practice, modern neural networks are almost always trained with some variant of stochastic gradient descent(SGD). Here we will provide two optimization algorithms: SGD and Adam optimizer. The goal of an optimization algorithm is to find the value of the parameter to make loss function very low. For some types of models, an optimization algorithm might find the global minimum value of loss function, but for neural network, the most efficient way to converge loss function to a local minimum is...
Gradient descent uses the following update rule to minimize loss function: where t is the time step of the algorithm and α\alphaα is the learning rate. But this rule could be very costly when L(θ)L(\theta)L(θ) is defined as a sum across the entire training set. Using SGD can accelerate the learning process as we can use only a batch of examples to update the parameters. We implemented the gradient descent algorithm, which can be viewed with the following code: There was an error while loading.
