Attributes |
|
---|---|
Name | Description |
type_ |
google.cloud.aiplatform_v1.types.ExplanationMetadata.InputMetadata.Visualization.Type
Type of the image visualization. Only applicable to [Integrated Gradients attribution][google.cloud.aiplatform.v1.ExplanationParameters.integrated_gradients_attribution]. OUTLINES shows regions of attribution, while PIXELS shows per-pixel attribution. Defaults to OUTLINES. |
polarity |
google.cloud.aiplatform_v1.types.ExplanationMetadata.InputMetadata.Visualization.Polarity
Whether to only highlight pixels with positive contributions, negative or both. Defaults to POSITIVE. |
color_map |
google.cloud.aiplatform_v1.types.ExplanationMetadata.InputMetadata.Visualization.ColorMap
The color scheme used for the highlighted areas. Defaults to PINK_GREEN for [Integrated Gradients attribution][google.cloud.aiplatform.v1.ExplanationParameters.integrated_gradients_attribution], which shows positive attributions in green and negative in pink. Defaults to VIRIDIS for [XRAI attribution][google.cloud.aiplatform.v1.ExplanationParameters.xrai_attribution], which highlights the most influential regions in yellow and the least influential in blue. |
clip_percent_upperbound |
float
Excludes attributions above the specified percentile from the highlighted areas. Using the clip_percent_upperbound and clip_percent_lowerbound together can be useful for filtering out noise and making it easier to see areas of strong attribution. Defaults to 99.9. |
clip_percent_lowerbound |
float
Excludes attributions below the specified percentile, from the highlighted areas. Defaults to 62. |
overlay_type |
google.cloud.aiplatform_v1.types.ExplanationMetadata.InputMetadata.Visualization.OverlayType
How the original image is displayed in the visualization. Adjusting the overlay can help increase visual clarity if the original image makes it difficult to view the visualization. Defaults to NONE. |
Classes
ColorMap
ColorMap(value)
The color scheme used for highlighting areas.
Enum values:
COLOR_MAP_UNSPECIFIED (0):
Should not be used.
PINK_GREEN (1):
Positive: green. Negative: pink.
VIRIDIS (2):
Viridis color map: A perceptually uniform
color mapping which is easier to see by those
with colorblindness and progresses from yellow
to green to blue. Positive: yellow. Negative:
blue.
RED (3):
Positive: red. Negative: red.
GREEN (4):
Positive: green. Negative: green.
RED_GREEN (6):
Positive: green. Negative: red.
PINK_WHITE_GREEN (5):
PiYG palette.
OverlayType
OverlayType(value)
How the original image is displayed in the visualization.
Enum values:
OVERLAY_TYPE_UNSPECIFIED (0):
Default value. This is the same as NONE.
NONE (1):
No overlay.
ORIGINAL (2):
The attributions are shown on top of the
original image.
GRAYSCALE (3):
The attributions are shown on top of
grayscaled version of the original image.
MASK_BLACK (4):
The attributions are used as a mask to reveal
predictive parts of the image and hide the
un-predictive parts.
Polarity
Polarity(value)
Whether to only highlight pixels with positive contributions, negative or both. Defaults to POSITIVE.
Enum values:
POLARITY_UNSPECIFIED (0):
Default value. This is the same as POSITIVE.
POSITIVE (1):
Highlights the pixels/outlines that were most
influential to the model's prediction.
NEGATIVE (2):
Setting polarity to negative highlights areas
that does not lead to the models's current
prediction.
BOTH (3):
Shows both positive and negative
attributions.
Type
Type(value)
Type of the image visualization. Only applicable to [Integrated Gradients attribution][google.cloud.aiplatform.v1.ExplanationParameters.integrated_gradients_attribution].
Enum values:
TYPE_UNSPECIFIED (0):
Should not be used.
PIXELS (1):
Shows which pixel contributed to the image
prediction.
OUTLINES (2):
Shows which region contributed to the image
prediction by outlining the region.
