Deep Learning ⊂ Machine Learning ⊂ Artificial Intelligence
Key Takeaways from This Module
- NLP is the AI field that enables computers to understand, process, and generate human language
- Computers process numbers, not words: text must be converted to numbers through tokenization and encoding
- Tokenization splits text into tokens. Modern models use subword tokenization (BPE)
- Common preprocessing: lowercase, remove punctuation, remove stopwords
- Sentiment analysis classifies the emotional tone of text
- Text classification assigns categories (topic, language, spam, intent) to text
- Chatbots range from rule-based to generative LLM-powered systems
- Translation and speech recognition use Transformer-based deep learning models
