We then loop through the data rows, augment the text column of each row using the <code>augment_text<\/code> function, and generate fake text data using the <code>Faker.text()<\/code> function with a maximum length of 500 characters. Finally, we write the augmented data to a new CSV file.<\/p>\n\n\n\n<p>Note that this is just one example of how you can do data augmentation for the <code>text<\/code> column. There are many other techniques you can use to generate augmented text data, such as adding noise or synonyms, or replacing some words with their antonyms. The choice of technique depends on the specific task and the nature of the text data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here&#8217;s an example of how you can generate a fake text column with some data augmentation technique using the Faker library in Python: In this example, we read the input&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19],"tags":[100,72,102,64],"class_list":["post-122","post","type-post","status-publish","format-standard","hentry","category-tutorials","tag-csv","tag-data-augmentation","tag-faker","tag-python"],"_links":{"self":[{"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/posts\/122","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/comments?post=122"}],"version-history":[{"count":1,"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/posts\/122\/revisions"}],"predecessor-version":[{"id":123,"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/posts\/122\/revisions\/123"}],"wp:attachment":[{"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/media?parent=122"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/categories?post=122"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/smartsource.com.sg\/blog\/index.php\/wp-json\/wp\/v2\/tags?post=122"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
