da2d2ea90e Switch to shared DINOv3 WEB encoder (saves ~4-5 GB VRAM) 
- Single DINOv3 WEB for both drone and satellite branches (shared_encoder=True default)
- One set of MONA adapters instead of two: 7M trainable vs 14M
- Total params: 438M (was 748M), trainable: 10.6M (was 17.6M)
- Asymmetric mode still available via shared_encoder=False
- Add gradient accumulation (grad_accum_steps, --grad-accum CLI flag)
- Update model summary in README

46b1208891 Add gradient accumulation support 
- New config field grad_accum_steps (default=1, no change in behavior)
- Loss scaled by 1/accum, optimizer step every N micro-batches
- Scheduler counts optimizer steps (not micro-batches)
- CLI flag --grad-accum for override
- Document gradient accumulation and in-batch negatives in README

69857e0ade Fix gin-config ambiguity: pin module name, remove redundant import 
- Use gin.configurable(module=...) to prevent __main__ vs module name clash
- Remove `import src.training.train_gtauav` from gin files (already loaded)
- Use short selector names (TrainConfigGTAUAV) in all gin configs

29a09349e7 Add ML diagnostics tooling (W&B, TensorBoard, Grad-CAM, profiler) and gin configs 
- Add unified experiment tracker (W&B + TensorBoard) with graceful fallback
- Add gradient norm monitoring per param group (MONA, LoRA, MLP, gates, tau)
- Add Grad-CAM visualization for DINOv3 drone/satellite encoders
- Add PyTorch Profiler wrapper + torchinfo model summary
- Add gin-config support to train_gtauav.py with CLI overrides
- Add v3 gin configs: gtauav_balanced, gtauav_baseline, gtauav_text_heavy, gtauav_image_heavy
- Generate metric plots every epoch (not just on eval)
- Set default epochs to 10
- Update README and CLAUDE.md with new tooling and usage docs

abb3337f8d Rewrite: GatedFusion architecture + UAV-GeoLoc dataset 
Architecture v2:
- Query branch: drone + text -> GatedFusion -> proj -> query_emb
- Gallery branch: satellite -> proj -> gallery_emb
- Single InfoNCE loss (asymmetric 0.6/0.4)
- GatedFusion: learnable gated addition (sigma(alpha)*img + (1-sigma(alpha))*text)
- Baseline mode: gate=1.0 (text ignored)

Dataset:
- UAV-GeoLoc loader with template captions from path metadata
- 27 terrain types with predefined features
- Random positive crop sampling per epoch

Configs: balanced (gate=0.7), baseline (no text), text_heavy (gate=0.3)

2ce4017ebd Initial commit: caption quality test on UAV-VisLoc 
Self-contained experimental track validating generated text captions
via retrieval R@1 lift on UAV-VisLoc.

Architecture: GeoRSCLIP ViT-B/32 dual encoder, 512-dim shared space.
Loss: 4-term InfoNCE (img-img + sat-cap + drone-cap + cap-cap)
      with cosine temperature decay, PALW-like curriculum.
Metric: delta R@1 (with text - without text) >= +3% => PASS.

Gin-configured (balanced / baseline_no_text / text_heavy variants).
Follows NADEZHDA code style.
