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).
A hyperparameter is a parameter whose value is used to control the learning process, which must be configured before the process starts. [2] [3] Hyperparameter optimization determines the set of hyperparameters that yields an optimal model which minimizes a predefined loss function on a given data set. [4]
In Bayesian statistics, a hyperparameter is a parameter of a prior distribution; the term is used to distinguish them from parameters of the model for the underlying system under analysis. For example, if one is using a beta distribution to model the distribution of the parameter p of a Bernoulli distribution , then:
New features like multi-stage DVC files, run cache, plots, data transfer optimizations, hyperparameter tracking, and stable release cycles were added as a result of discussions and contributions from the community. In March 2021, [49] DVC released DVC 2.0, which introduced ML experiments (experiment management), model checkpoints and metrics ...
The parameter is called the hyperparameter, while its distribution given by (,) is an example of a hyperprior distribution. The notation of the distribution of Y changes as another parameter is added, i.e. Y ∣ θ , μ ∼ N ( θ , 1 ) {\displaystyle Y\mid \theta ,\mu \sim N(\theta ,1)} .
A set of PowerToys for Windows Media Player was released as part of the Windows Media Player Bonus Pack (for Windows XP), consisting of five tools to "provide a variety of enhancements to Windows Media Player." [41] [42] Finally, Microsoft has also released PowerToys for Windows Mobile, Visual Studio [43] [44] [45] and OneNote. [46] [47]

Empirical Bayes methods can be seen as an approximation to a fully Bayesian treatment of a hierarchical Bayes model.. In, for example, a two-stage hierarchical Bayes model, observed data = {,, …,} are assumed to be generated from an unobserved set of parameters = {,, …,} according to a probability distribution ().
