Reference documentation and code samples for the Vertex AI V1 API class Google::Cloud::AIPlatform::V1::XraiAttribution.

An explanation method that redistributes Integrated Gradients attributions to segmented regions, taking advantage of the model's fully differentiable structure. Refer to this paper for more details: https://arxiv.org/abs/1906.02825

Supported only by image Models.

Methods

#blur_baseline_config

def blur_baseline_config() -> ::Google::Cloud::AIPlatform::V1::BlurBaselineConfig

Returns

• (::Google::Cloud::AIPlatform::V1::BlurBaselineConfig) — Config for XRAI with blur baseline.

  When enabled, a linear path from the maximally blurred image to the input image is created. Using a blurred baseline instead of zero (black image) is motivated by the BlurIG approach explained here: https://arxiv.org/abs/2004.03383

#blur_baseline_config=

def blur_baseline_config=(value) -> ::Google::Cloud::AIPlatform::V1::BlurBaselineConfig

Parameter

• value (::Google::Cloud::AIPlatform::V1::BlurBaselineConfig) — Config for XRAI with blur baseline.

#smooth_grad_config

def smooth_grad_config() -> ::Google::Cloud::AIPlatform::V1::SmoothGradConfig

Returns

• (::Google::Cloud::AIPlatform::V1::SmoothGradConfig) — 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

#smooth_grad_config=

#step_count

def step_count() -> ::Integer

Returns

• (::Integer) — Required. The number of steps for approximating the path integral. A good value to start is 50 and gradually increase until the sum to diff property is met within the desired error range.

  Valid range of its value is [1, 100], inclusively.
