    • learningRate

      public final Double learningRate()

      The learning rate for the optimizer. Must be greater than 0.

      Returns:
      The learning rate for the optimizer. Must be greater than 0.

    • beta1

      public final Double beta1()

      The exponential decay rate for the first moment estimates.

      Returns:
      The exponential decay rate for the first moment estimates.

    • beta2

      public final Double beta2()

      The exponential decay rate for the second moment estimates.

      Returns:
      The exponential decay rate for the second moment estimates.

    • eps

      public final Double eps()

      A small constant added to the denominator for numerical stability.

      Returns:
      A small constant added to the denominator for numerical stability.

    • weightDecay

      public final Double weightDecay()

      The weight decay (L2 regularization) coefficient.

      Returns:
      The weight decay (L2 regularization) coefficient.

    • gradClipNorm

      public final Double gradClipNorm()

      The maximum gradient norm for gradient clipping. Gradients are scaled down if their norm exceeds this value.

      Returns:
      The maximum gradient norm for gradient clipping. Gradients are scaled down if their norm exceeds this value.

    • loraPlusLrRatio

      public final Double loraPlusLrRatio()

      The learning rate multiplier for LoRA+ B matrices relative to A matrices. When set, B matrices use learningRate * loraPlusLrRatio while A matrices use the base learning rate.

      Returns:
      The learning rate multiplier for LoRA+ B matrices relative to A matrices. When set, B matrices use learningRate * loraPlusLrRatio while A matrices use the base learning rate.

    • toBuilder

      public AdamParamsConfig.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<AdamParamsConfig.Builder,AdamParamsConfig>
      Returns:
      a builder for type T

    • builder

      public static AdamParamsConfig.Builder builder()

    • serializableBuilderClass

      public static Class<? extends AdamParamsConfig.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
