This can occur due to either mislabeled data, or when the data collected is missing features necessary to separate the labels. If the data is mislabled, it can confuse the model and can result in lower performance of the model. ..

.. GENERATED FROM PYTHON SOURCE LINES 55-60 Define a Condition ================== Now, we define a condition that enforces that the ratio of samples with conflicting labels should be 0. A condition is deepchecks' way to validate model and data quality, and let you know if anything goes wrong. ..
