Finding mismatches in strings is helpful for identifying errors in the data. For example, if your data is aggregated from multiple sources, it might have the same values but with a little variation in the formatting, like a leading uppercase. In this case, the model's ability to learn may be impaired since it will see categories that are supposed to be the same, as different categories. How String Mismatch Defined? ---------------------------- To recognize string mismatch, we transform each string to it's base form. The base form is the string with only its alphanumeric characters in lowercase. (For example "Cat-9?!" base form is "cat9"). If two strings have the same base form, they are considered to be the same. .. GENERATED FROM PYTHON SOURCE LINES 32-34 Run the Check ========= ..
