Text Representation Using TF-IDF: NLP Tutorial For Beginners - S2 E6

TF-IDF (term frequency, inverse document frequency) is a text representation technique in NLP that tackles the word count influence of common English words such as the, is etc (stop words) and some other generic words that are not stop words but can appear in any document. The idea is to give a high score to terms that are really relevant to a given document. In this video, I will explain TF-IDF in a very simple manner such that even a high school student can understand it easily 😊 Code: https://github.com/codebasics/nlp-tutorials/blob/main/12_tf_idf/tf_idf_tutorial_nlp_codebasics.ipynb Exercise: https://github.com/codebasics/nlp-tutorials/blob/main/12_tf_idf/tf_idf_exercise.ipynb Complete NLP Playlist: https://www.youtube.com/playlist?list=PLeo1K3hjS3uuvuAXhYjV2lMEShq2UYSwX ⭐️ Timestamps ⭐️ 00:00 What is TF-IDF 11:32 Limitations of TF-IDF 12:17 Coding: sklearn TfidfVectorizer 21:38 Coding: Ecommerce item category classification using tf-idf Stackoverflow question on usage of log in tf-idf formula: https://stackoverflow.com/questions/27067992/why-is-log-used-when-calculating-term-frequency-weight-and-idf-inverse-document#:~:text=Log%20is%20said%20to%20be,dampens%E2%80%9D%20the%20effect%20of%20IDF. #tfidf #naturallanguageprocessing #textanalytics Practical NLP Book In India: https://www.shroffpublishers.com/books/computer-science/artificial-intelligence/natural-language-processing/9789385889189/ Practical NLP Book Link For USA: https://amzn.to/3Aoeocm 🔖Hashtags🔖 #nlp #nlptutorial #nlppython #nlptfidf #whatistfidf #tfidfintuition #tfidf #tfidfnlp Do you want to learn technology from me?
