Overview

Config for SmoothGrad approximation of gradients. When enabled, the gradients are approximated by averaging the gradients from noisy samples in the vicinity of the inputs. Adding noise can help improve the computed gradients. Refer to this paper for more details: https://arxiv.org/pdf/1706.03825.pdf

Instance Attribute Details

#feature_noise_sigma ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1FeatureNoiseSigma

Noise sigma by features. Noise sigma represents the standard deviation of the gaussian kernel that will be used to add noise to interpolated inputs prior to computing gradients. Corresponds to the JSON property featureNoiseSigma

Returns:

def feature_noise_sigma
  @feature_noise_sigma
end

#noise_sigma ⇒ Float

This is a single float value and will be used to add noise to all the features. Use this field when all features are normalized to have the same distribution: scale to range [0, 1], [-1, 1] or z-scoring, where features are normalized to have 0-mean and 1-variance. Learn more about normalization. For best results the recommended value is about 10% - 20% of the standard deviation of the input feature. Refer to section 3.2 of the SmoothGrad paper: https://arxiv.org/pdf/1706.03825.pdf. Defaults to 0.1. If the distribution is different per feature, set feature_noise_sigma instead for each feature. Corresponds to the JSON property noiseSigma

Returns:

  • (Float)

def noise_sigma
  @noise_sigma
end

#noisy_sample_count ⇒ Fixnum

The number of gradient samples to use for approximation. The higher this number, the more accurate the gradient is, but the runtime complexity increases by this factor as well. Valid range of its value is [1, 50]. Defaults to 3. Corresponds to the JSON property noisySampleCount

Returns:

  • (Fixnum)
