 ## Access data using TabularDataset function
 
-Defined X and y as `TabularDataset`s, which are passed to Automated ML in the AutoMLConfig. `from_delimited_files` by default sets the `infer_column_types` to true, which will infer the columns type automatically. 
+Defined training_data as  `TabularDataset`and the label , which are passed to Automated ML in the AutoMLConfig. `from_delimited_files` by default sets the `infer_column_types` to true, which will infer the columns type automatically. 
 
 If you do wish to manually set the column types, you can set the `set_column_types` argument to manually set the type of each columns. In the following code sample, the data comes from the sklearn package.
