There are many options for optimizer in Tensorflow. Optimizers are the tool to minimise loss between prediction and real value. There are many, many different weights our model could learn, and brute-force testing every one would take forever. Instead, we choose an optimizer which evaluates our loss value, and smartly updates our weights. Click here For a list of Keras optimizer functions.
