metric_mean_squared_logarithmic_error: Computes the mean squared logarithmic error

In keras: R Interface to 'Keras'

Computes the mean squared logarithmic error

Description

Computes the mean squared logarithmic error

Usage

metric_mean_squared_logarithmic_error(
  y_true,
  y_pred,
  ...,
  name = "mean_squared_logarithmic_error",
  dtype = NULL
)

Arguments

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.

Details

loss = mean(square(log(y_true + 1) - log(y_pred + 1)), axis=-1)

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.
