Language Models and Text Generation

What are Language Models?

A language model is a probabilistic model that learns to predict the probability of word sequences, enabling it to generate coherent and contextually appropriate text.
How they work:

• Learn from massive text datasets
• Predict the next word in a sequence
• Capture patterns and context
• Generate human-like text
🧠 Key Insight:
Language models don't truly "understand" text like humans do, but they become very good at statistical pattern matching and generation!

Types of Language Models

📊 N-gram Models
Statistical models based on word sequences (bigrams, trigrams)
🧠 Neural Language Models
RNN/LSTM-based models that capture longer dependencies
⚡ Transformer Models
Modern attention-based models like GPT and BERT
🚀 Large Language Models
Massive models with billions of parameters (GPT-3, GPT-4)
