turicreate.evaluation.rmse — Turi Create API 6.4.1 documentation (original) (raw)
turicreate.evaluation. rmse(targets, predictions)¶
Compute the root mean squared error between two SArrays.
| Parameters: | targets : SArray[float or int] An Sarray of ground truth target values. predictions : SArray[float or int] The prediction that corresponds to each target value. This vector must have the same length as targets. |
|---|---|
| Returns: | out : float The RMSE between the two SArrays. |
Notes
The root mean squared error between two vectors, x and y, is defined as:
\[RMSE = \sqrt{\frac{1}{N} \sum_{i=1}^N (x_i - y_i)^2}\]
