metric_poisson
Computes the Poisson metric between y_true and y_pred
Description
metric = y_pred - y_true * log(y_pred)
Usage
metric_poisson(y_true, y_pred, ..., name = "poisson", dtype = NULL) Arguments
| Arguments | Description |
|---|---|
| y_true | Tensor of true targets. |
| y_pred | Tensor of predicted targets. |
| … | Passed on to the underlying metric. Used for forwards and backwards compatibility. |
| name | (Optional) string name of the metric instance. |
| dtype | (Optional) data type of the metric result. |
Value
If y_true and y_pred are missing, a (subclassed) Metric instance is returned. The Metric object can be passed directly to compile(metrics = ) or used as a standalone object. See ?Metric for example usage. Alternatively, if called with y_true and y_pred arguments, then the computed case-wise values for the mini-batch are returned directly.
