dummy dataset

A dummy dataset is a synthetic dataset created for testing, training, or evaluating machine learning models when real data is unavailable or unsuitable. These datasets are particularly useful in scenarios where real data may be sensitive or confidential, allowing developers to work without compromising privacy.

There are several methods to create dummy datasets in Python. One popular approach is using the make_classification method from the Sklearn library, which allows you to generate a numerical dataset with specified parameters such as the number of samples and features. This method can create informative and redundant features, which can help in testing various model scenarios 15.

Another option is to use the Faker library, which generates fake data for various purposes, including filling databases or testing applications. This library is easy to use and can produce a wide range of data types 4.

Creating dummy datasets can save time and effort, especially when searching for open-source datasets that may not meet specific requirements 1.
