We do this by assigning the call to minimize to a 3. Keras Adam Optimizer (Adaptive Moment Estimation) The adam optimizer uses adam algorithm in which the stochastic gradient descent method is leveraged for performing the optimization process. It is efficient to use and consumes very little memory. It is appropriate in cases where huge amount of data and parameters are available for usage. The cost function is synonymous with a loss function. To optimize our cost, we will use the AdamOptimizer, which is a popular optimizer along with others like Stochastic Gradient Descent and AdaGrad, for example. I am experimenting with some simple models in tensorflow, including one that looks very similar to the first MNIST for ML Beginners example, but with a somewhat larger dimensionality.
