AutoMLChannel
A channel is a named input source that training algorithms can consume. The validation dataset size is limited to less than 2 GB. The training dataset size must be less than 100 GB. For more information, see Channel.
Note
A validation dataset must contain the same headers as the training dataset.
Contents
- DataSource
-

Type: AutoMLDataSource object
Required: Yes
- TargetAttributeName
-
The name of the target variable in supervised learning, usually represented by 'y'.
Type: String
Length Constraints: Minimum length of 1.
Required: Yes
- ChannelType
-
The channel type (optional) is an
enumstring. The default value istraining. Channels for training and validation must share the sameContentTypeandTargetAttributeName. For information on specifying training and validation channel types, see How to specify training and validation datasets.Type: String

- SampleWeightAttributeName
-
If specified, this column name indicates which column of the dataset should be treated as sample weights for use by the objective metric during the training, evaluation, and the selection of the best model. This column is not considered as a predictive feature. For more information on Autopilot metrics, see Metrics and validation.
Sample weights should be numeric, non-negative, with larger values indicating which rows are more important than others. Data points that have invalid or no weight value are excluded.
Support for sample weights is available in Ensembling mode only.
