Instance Attribute Details

#auto ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationAutoTransformation

Training pipeline will infer the proper transformation based on the statistic of dataset. Corresponds to the JSON property auto

Returns:

# File 'lib/google/apis/aiplatform_v1/classes.rb', line 30428

def auto
  @auto
end

#categorical ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationCategoricalTransformation

Training pipeline will perform following transformation functions. * The categorical string as is--no change to case, punctuation, spelling, tense, and so on. * Convert the category name to a dictionary lookup index and generate an embedding for each index. * Categories that appear less than 5 times in the training dataset are treated as the "unknown" category. The "unknown" category gets its own special lookup index and resulting embedding. Corresponds to the JSON property categorical

Returns:

def categorical
  @categorical
end

#numeric ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationNumericTransformation

Training pipeline will perform following transformation functions. * The value converted to float32. * The z_score of the value. * log(value+1) when the value is greater than or equal to 0. Otherwise, this transformation is not applied and the value is considered a missing value. * z_score of log(value+1) when the value is greater than or equal to 0. Otherwise, this transformation is not applied and the value is considered a missing value. * A boolean value that indicates whether the value is valid. Corresponds to the JSON property numeric

Returns:

def numeric
  @numeric
end

#repeated_categorical ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationCategoricalArrayTransformation

Treats the column as categorical array and performs following transformation functions. * For each element in the array, convert the category name to a dictionary lookup index and generate an embedding for each index. Combine the embedding of all elements into a single embedding using the mean. * Empty arrays treated as an embedding of zeroes. Corresponds to the JSON property repeatedCategorical

Returns:

# File 'lib/google/apis/aiplatform_v1/classes.rb', line 30458

def repeated_categorical
  @repeated_categorical
end

#repeated_numeric ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationNumericArrayTransformation

Treats the column as numerical array and performs following transformation functions. * All transformations for Numerical types applied to the average of the all elements. * The average of empty arrays is treated as zero. Corresponds to the JSON property repeatedNumeric

Returns:

# File 'lib/google/apis/aiplatform_v1/classes.rb', line 30465

def repeated_numeric
  @repeated_numeric
end

#repeated_text ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationTextArrayTransformation

Treats the column as text array and performs following transformation functions. * Concatenate all text values in the array into a single text value using a space (" ") as a delimiter, and then treat the result as a single text value. Apply the transformations for Text columns. * Empty arrays treated as an empty text. Corresponds to the JSON property repeatedText

Returns:



30474
30475
30476
 
# File 'lib/google/apis/aiplatform_v1/classes.rb', line 30474

def repeated_text
  @repeated_text
end

#text ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationTextTransformation

Training pipeline will perform following transformation functions. * The text as is--no change to case, punctuation, spelling, tense, and so on. * Tokenize text to words. Convert each words to a dictionary lookup index and generate an embedding for each index. Combine the embedding of all elements into a single embedding using the mean. * Tokenization is based on unicode script boundaries.

  • Missing values get their own lookup index and resulting embedding. * Stop- words receive no special treatment and are not removed. Corresponds to the JSON property text

Returns:



30485

30487
 
# File 'lib/google/apis/aiplatform_v1/classes.rb', line 30485

def text
  @text
end

#timestamp ⇒ Google::Apis::AiplatformV1::GoogleCloudAiplatformV1SchemaTrainingjobDefinitionAutoMlTablesInputsTransformationTimestampTransformation

Training pipeline will perform following transformation functions. * Apply the transformation functions for Numerical columns. * Determine the year, month, day,and weekday. Treat each value from the * timestamp as a Categorical column.

  • Invalid numerical values (for example, values that fall outside of a typical timestamp range, or are extreme values) receive no special treatment and are not removed. Corresponds to the JSON property timestamp

Returns:



30495
30496
30497
 
# File 'lib/google/apis/aiplatform_v1/classes.rb', line 30495

def timestamp
  @timestamp
