Experiment Object
/experiments/EXPERIMENT_IDAn experiment represents an objective that SigOpt is optimizing, the relevant parameters, and the underlying data.
Key | Type | Value |
|---|---|---|
client | string | The id of the Client who created the SigOpt Experiment. |
conditionals | ||
created | int | The timestamp (in seconds since epoch) that this experiment was created. |
id | string | A unique ID for a given experiment. |
linear_constraints | ||
metadata | Optional user-provided metadata. | |
metrics | An array of Metric objects to be optimized or stored for analysis. Use only a single entry for the standard single criterion optimization problem. This array can have no more than 2 entries marked for optimization and no more than 50 entries in total. See Define and Set up Metric Space for more information. | |
name | string | A user-specified name for this experiment. |
num_solutions | int | The number of solutions you want for your experiment. The default number of solutions is 1. See Multisolution for more information. |
observation_budget | int | SeThe number of Observations you plan to create for this experiment. We recommend this value be between 10x and 20x the number of parameters. This can be thought of as a lower bound on the number of observations you will create. Failing to reach this value may result in suboptimal performance for your experiment. |
parallel_bandwidth | int | The number of simultaneously open Suggestions you plan to maintain during this experiment. The default value for this is 1, i.e., a sequential experiment. The maximum value for this is dependent on your plan. This field is optional, but setting it correctly may improve performance. |
parameters | ||
progress | The current progress of this experiment. | |
state | string | The state of this experiment. Can be active (for experiments that are currently running), or deleted (for experiments that have been deleted). |
type | string | A type for this experiment. Used for random and grid. |
updated | int | The timestamp (in seconds since epoch) that this experiment was last updated. |
user | string | The id of the user who created the experiment. |
These fields should no longer be used because there are better alternatives.
