Self-Attention in Transformers: The Engine Behind Large Language Model Understanding
Discover how self-attention powers large language models. Learn the query-key-value mechanism, multi-head attention, and why transformers outperform RNNs in understanding context.
Positional Encoding in Transformers: Sinusoidal vs Learned for LLMs
Sinusoidal and learned positional encodings were early solutions for transformers, but modern LLMs now use RoPE and ALiBi for better long-context performance. Learn why and how these techniques evolved.
