Instance Attribute Details

#duration_ms ⇒ Fixnum

[Output-only, Beta] Time taken to run the training iteration in milliseconds. Corresponds to the JSON property durationMs

Returns:

  • (Fixnum)

def duration_ms
  @duration_ms
end

#eval_loss ⇒ Float

[Output-only, Beta] Eval loss computed on the eval data at the end of the iteration. The eval loss is used for early stopping to avoid overfitting. No eval loss if eval_split_method option is specified as no_split or auto_split with input data size less than 500 rows. Corresponds to the JSON property evalLoss

Returns:

  • (Float)

  @eval_loss
end

#index ⇒ Fixnum

[Output-only, Beta] Index of the ML training iteration, starting from zero for each training run. Corresponds to the JSON property index

Returns:

  • (Fixnum)

def index
  @index
end

#learn_rate ⇒ Float

[Output-only, Beta] Learning rate used for this iteration, it varies for different training iterations if learn_rate_strategy option is not constant. Corresponds to the JSON property learnRate

Returns:

  • (Float)

end

#training_loss ⇒ Float

[Output-only, Beta] Training loss computed on the training data at the end of the iteration. The training loss function is defined by model type. Corresponds to the JSON property trainingLoss

Returns:

  • (Float)
