In the adaptive control literature, the learning rate is commonly referred to as gain. [2] In setting a learning rate, there is a trade-off between the rate of convergence and overshooting. While the descent direction is usually determined from the gradient of the loss function, the learning rate determines how big a step is taken in that ...
In machine learning, the Goldilocks learning rate is the learning rate that results in an algorithm taking the fewest steps to achieve minimal loss. Algorithms with a learning rate that is too large often fail to converge at all, while those with too small a learning rate take too long to converge. [12]
AdaGrad (for adaptive gradient algorithm) is a modified stochastic gradient descent algorithm with per-parameter learning rate, first published in 2011. [38] Informally, this increases the learning rate for sparser parameters [clarification needed] and decreases the learning rate for ones that are less sparse. This strategy often improves ...
Since using a step size that is too small would slow convergence, and a too large would lead to overshoot and divergence, finding a good setting of is an important practical problem. Philip Wolfe also advocated using "clever choices of the [descent] direction" in practice. [ 10 ]
A learning curve is a graphical representation of the relationship between how proficient people are at a task and the amount of experience they have. Proficiency (measured on the vertical axis) usually increases with increased experience (the horizontal axis), that is to say, the more someone, groups, companies or industries perform a task, the better their performance at the task.
Just like gamblers place bets on boxers who fight in divisions based on their weight, investors, too, put their money down on stocks that are grouped together by size. All publicly traded companies...

In machine learning, a hyperparameter is a parameter that can be set in order to define any configurable part of a model's learning process. Hyperparameters can be classified as either model hyperparameters (such as the topology and size of a neural network) or algorithm hyperparameters (such as the learning rate and the batch size of an optimizer).
