Adam Optimizer Definition

The Adam (Adaptive Moment Estimation) Optimizer is a popular optimization algorithm in machine learning, specifically designed for training deep neural networks. Adam combines the best properties of the AdaGrad and RMSProp algorithms, using adaptive learning rates to adjust weights based on past gradients. This makes it effective in optimizing both sparse and noisy data and fast in converging to minimal error values, often used for minimizing the loss function in models. Adam achieves this by maintaining two moment estimates: the first for the mean of gradients and the second for the variance, enabling it to adapt learning rates independently for each parameter.

Adam Optimizer Explained Easy

Imagine you’re trying to learn how to play a new video game. At first, you’re unsure what moves work best, so you try different things each time you play. Over time, you remember which moves helped you win and which didn’t. This optimizer works similarly, learning from previous mistakes to help the computer make better guesses next time.

Adam Optimizer Origin

Adam was introduced in 2015 by researchers Diederik P. Kingma and Jimmy Ba as an improvement over other optimization algorithms, addressing issues of computation time and adaptability for complex, deep learning models. Since then, it has become widely used across various neural network applications.



Adam Optimizer Etymology

The name “Adam” stands for "Adaptive Moment Estimation," capturing the algorithm’s ability to use past moments (gradients) to adjust future learning steps.
