Problem

Has AutoML framework but missing specific NAS algorithms.

Existing

• src/AutoML/NeuralArchitectureSearch.cs (framework)
• src/AutoML/NeuralArchitectureSearchStrategy.cs
• src/AutoML/IAutoMLModel.cs

Missing Implementations

Differentiable NAS (CRITICAL):

• DARTS (Differentiable Architecture Search)
• GDAS (Gradient-based NAS)
• PC-DARTS (Partial Channel DARTS)

Efficient NAS (HIGH):

• ENAS (Efficient Neural Architecture Search)
• ProxylessNAS
• FBNet (hardware-aware NAS)

One-Shot NAS (HIGH):

• Once-for-All Networks
• BigNAS
• AttentiveNAS

Search Spaces (MEDIUM):

• MobileNet search space
• ResNet search space
• Transformer search space

Architecture

• Expand src/AutoML/NAS/
• Search space definitions
• Hardware cost modeling

Success Criteria

• ImageNet architecture search
• Transfer to downstream tasks
• Hardware latency constraints
• Parity with NAS-Bench-201
