Parameter Object
A parameter is a variable that can affect a single experiment trial. SigOpt will suggest values for your parameters in order to optimize the relevant objective.
double and int parameters represent numeric values. categorical parameters take on one of a fixed list of values (similar to an enum in many programming languages).Key | Type | Value |
|---|---|---|
bounds | A range of values that a parameter can occupy. Only applicable for parameters of type double or int. | |
categorical_values | ||
conditions | ||
default_value | string or number | Used to replace missing parameter assignments in parameters added after initial experiment creation. |
grid | array<double> | Only applicable for parameters of type double and int. The discrete numerical values that a parameter can take. When grid is provided, bounds should not be set. Refer to the Grid Values documentation for more information. |
name | string | A user-specified name for this parameter. |
precision | int | Only applicable for parameters of type double. The number of decimal places when displaying on the web dashboard. |
prior | Only applicable for parameters of type double. The prior distribution of the parameter. Refer to the Prior Beliefs documentation for more information. | |
transformation | string | Only applicable to parameters of type double. The scale of a parameter. Refer to the Parameter transformation documentation for more information. |
type | string | The type of this parameter. Must be one of double, int, or categorical. |
