Transformers Tutorial ⚡: Attention Mechanism Explained – Parallel Seq Magic

Hack into transformers guide – the powerhouse behind modern large language models.

Attention Mechanism Explained

• QKV: Query, Key, Value vectors for scoring.
• Self-Attention: Tokens interact and weigh importance.
• Multi-Head Attention: Multiple perspectives for richer representations.

Transformers Architecture

• Encoder: Stacked attention + feed-forward layers.
• Decoder: Masked attention + cross-attention.
• Positional Encoding: Sine/cosine to maintain order.

Training Transformers

• Autoregressive: Predict next token in sequence.
• Scaling: Bigger models, more data = better performance.
