How does the optimizer `tf.keras.optimizers.Adam()` work?

WebOct 7, 2024 · An optimizer is a function or an algorithm that modifies the attributes of the neural network, such as weights and learning rates. Thus, it helps in reducing the overall loss and improving accuracy. The problem of choosing the right weights for the model is a daunting task, as a deep learning model generally consists of millions of parameters. WebMar 5, 2016 · Adam uses the initial learning rate, or step size according to the original paper's terminology, while adaptively computing updates. Step size also gives an approximate bound for updates. In this regard, I think it is a good idea to reduce step size towards the end of training.
