StoppingCriteria

case class StoppingCriteria(maxIter: Int = 100000, patience: Int = 5000, patienceStep: Int = 2, improveThreshold: Double = 0.995, lossThreshold: Double = 1.0E-4, validationFreq: Int = 100) extends Serializable with Product

Criteria: When to stop training

This case class defines when to stop training. Training stops if one of the following condition is satisfied.

Validation is done for each validationFreq iterations, and whenever current/best loss ratio below improveThreshold, that iteration is marked as best iteration.

maxIter

maximum mini-batch iteration count (default 100,000)

patience

default patience count (default 5,000)

patienceStep

multiplier for calculating patience (default x2)

improveThreshold

threshold that iteration is marked as "improved" (default 95% = 0.95)

lossThreshold

maximum-tolerant loss value. (default 0.0001)

validationFreq

step count for validation (default 100)
