The following methods can be used to handle non-standard data:

1. Data Cleaning: Non-standard data may contain noise, missing values, duplicate values, and other issues that require data cleaning. Python’s pandas library can be used for data cleaning tasks such as removing duplicate values, filling missing values, and deleting outliers.
2. Data transformation: Non-standard data may contain different data types that require conversion for easier analysis. You can use the pandas library in Python to convert data types, such as converting string data to numeric data or date data to standard date format.
3. Feature extraction: Non-standardized data may contain some valuable information, but it needs to be extracted in order to use it. The Python regular expression library re can be used to extract key information from text, such as extracting phone numbers, emails, URLs, etc.
4. Text analysis: Unstructured data may contain text data, requiring text analysis. Python’s nltk library can be used for text analysis, such as tokenization, word frequency counting, sentiment analysis, and more.
5. Data standardization: Non-standardized data may have issues such as inconsistent units and dimensions, requiring data standardization. This can be done using Python’s scikit-learn library, for example scaling the data to a specific range, transforming the data to have a mean of 0 and variance of 1 in a standard normal distribution, etc.

The above are some common methods for handling non-standard data, and the specific approach should be chosen based on the specific circumstances of the data.
