Natural Language Processing (NLP)

This practical guide provides a complete overview of NLP, from tokenization to large language models.

NLP is one of the most dynamic fields in machine learning, enabling computers to understand, process, and generate human language. This guide covers everything you need to know, from traditional approaches to modern transformers.

Fine-tuning Pre-trained Models: Strategies

Full Fine-tuning: Training all parameters requires significant computational resources.

Layer-wise Fine-tuning: Gradually unfreezing layers allows for efficient adaptation to specific datasets.

Softmax for Normalizing Scores in Weights

Weighted Sum of Values: Attention(Q,K,V) = softmax(QK^T/√d)V

Multi-Head Attention: Multiple parallel attention mechanisms capture different types of dependencies. The results are concatenated.
