This skill covers modern transformer variants (LSH attention, Linformer, Performer, Longformer, FLASH) optimized for long sequences and low-resource settings. ML engineers earn $150-260k mid-to-senior, essential for deployment and research.

Attention Transformers Variants ಎಂದರೇನು

Modern transformers use dozens of attention variants optimized for specific constraints: sequence length, memory, latency. Sparse attention (Longformer, BigBird), linear-time attention (Performer, Mamba), and retrieval-augmented variants reduce the computational burden of standard O(n^2) attention while preserving expressiveness. Production models often require efficiency. This skill is critical for deploying LLMs on resource-constrained devices, handling long documents, and optimizing inference. Key reasons:

❓ FAQ

What problem do attention variants solve?
Standard attention is O(n^2) in sequence length; variants reduce this to O(n log n) or O(n), enabling longer context windows and faster inference.
When should I use sparse attention vs. linear attention?
Sparse (local + strided) is better when relevant context is nearby; linear (Performer, Mamba) is better for very long sequences with global dependencies.
Does Longformer sacrifice accuracy for speed?
Not significantly. Local windowed attention plus sparse global attention preserves important context. Trade-offs are task-dependent.
What is FAVOR+ and why is it important?
FAVOR+ approximates softmax attention using random features; Performer uses it for linear-time attention without sacrificing accuracy. Elegant mathematical trick.
How do I know which variant to use for my task?
Start with standard attention, measure memory/latency, then experiment. Long-document understanding → Longformer/BigBird; high-speed inference → Performer.
Can variants replace standard attention entirely?
Not always. Some tasks (fine-grained attention requirements) still prefer O(n^2) standard attention. Hybrid approaches (local + sparse global) often win.
