Classical Machine Learning for NLP

Classical machine learning for NLP refers to traditional statistical and machine learning techniques applied to natural language processing tasks, such as text classification, sentiment analysis, and named entity recognition. It involves feature engineering from text data (e.g., bag-of-words, TF-IDF) and using algorithms like Naive Bayes, Support Vector Machines, or Random Forests for modeling, predating the dominance of deep learning in NLP.

Also known as: Traditional ML for NLP, Statistical NLP, Feature-based NLP, Pre-deep learning NLP, ML-based NLP

Why learn Classical Machine Learning for NLP?

Developers should learn this for interpretable, lightweight solutions in resource-constrained environments or when dealing with small datasets, as it often requires less computational power than deep learning. It's particularly useful in applications like spam detection, topic modeling, or basic text analytics where transparency and efficiency are prioritized over state-of-the-art accuracy.
