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 a hidden issue we're not expecting to occur, it may be an indicator for a problem in the data pipeline that requires attention. Create TextData =============== Let's create a simple dataset with some duplicate and similar text samples. ..

Text Duplicates

.. GENERATED FROM PYTHON SOURCE LINES 63-68 With Text Normalization ----------------------- By default, ``TextDuplicates`` check applies text normalization before identifying the duplicates. This includes case normalization, punctuation removal, Unicode normalization and stopwords removal. You can also customize the normalization as per your requirements: ..

Text Duplicates

.. GENERATED FROM PYTHON SOURCE LINES 78-86 Of all the parameters in this example, ``ignore_whitespace`` is the only one set to ``False`` by default. Define a Condition ================== Now, we define a condition that enforces the ratio of duplicates to be 0. A condition is deepchecks' way to validate model and data quality, and let you know if anything goes wrong. ..
