What is String Length Out Of Bounds

The StringLengthOutOfBounds check detects strings with length that is much longer/shorter than the identified “normal” string lengths.

import pandas as pd

from deepchecks.tabular.checks import StringLengthOutOfBounds
from deepchecks.tabular import Dataset

Generate Data

col1 = ["deepchecks123", "deepchecks456"]*40
col1.append("ab")
col1.append("cd")

col2 = ["b", "abc"]*41

col3 = ["deepchecks"]*80
col3.append("an_outlier")
col3.append("im_an_outlier_too")

## col1 and col3 contain outliers, col2 does not
df = pd.DataFrame({"col1":col1, "col2": col2, "col3": col3 })
df = Dataset(df, cat_features=[])

Run the check

StringLengthOutOfBounds().run(df)
