GENERATED FROM PYTHON SOURCE LINES 27-38 Why data duplicates? ==================== The ``DataDuplicates`` check finds multiple instances of identical samples in the Dataset. Duplicate samples increase the weight the model gives to those samples. If these duplicates are there intentionally (e.g. as a result of intentional oversampling, or due to the dataset's nature it has identical-looking samples) this may be valid, however if this is an hidden issue we're not expecting to occur, it may be an indicator for a problem in the data pipeline that requires attention.

A condition is deepchecks' way to validate model and data quality, and let you know if anything goes wrong. ..
