Training Configuration
+
+
+ +
+ + + + Override the base model checkpoint to finetune from. If left empty, the system will attempt to extract it from the model configuration or script. + +
+ +
+
+
+ + + Higher rank = more trainable parameters +
+
+
+
+ + + Typical range: 10-20 epochs +
+
+
+ +
+
+
+ + + Higher = faster but uses more GPU memory +
+
+
+
+ + + LoRA typically uses higher learning rates +
+
+
+ +
+
+
+ + + Margin is recommended for sparse annotations +
+
+
+
+ + + Keeps model close to original predictions +
+
+
+
+
+
+ + + Where to apply distillation loss +
+
+
+
+
+ + +
+ Weight fg and bg equally in loss regardless of scribble ratio. Prevents foreground overprediction. +

Choose the model you want to finetune from the dropdown + - The crop will be automatically sized to the model's output inference shape + - Models must be configured with `write_shape`, `output_voxel_size`, and `output_channels` +2.

`MIN_POINT_DISTANCE` | 5 | Minimum spacing between points (voxels) | +| `BACKGROUND_MIN_DIST` | 2 | Min distance from mito for background | +| `BACKGROUND_MAX_DIST` | 10 | Max distance from mito for background | + +### Training + +| Parameter | Default | Description | +|-----------|---------|-------------| +| `mask_unannotated` | `True` | Only compute loss on labeled regions | +| `loss_type` | `"combined"` | Loss function (dice/bce/combined) | +| `learning_rate` | `1e-4` | Learning rate | +| `num_epochs` | `10` | Training epochs | + +## How the Masking Works + +When `mask_unannotated=True` in the trainer: + +1. **Mask Creation:** + ```python + mask = (target > 0).float() # Binary mask of annotated regions + ``` + +2. **Label Shifting:** + ```python + target = torch.clamp(target - 1, min=0) # 0→0, 1→0, 2→1 + ``` + +3. **Loss Computation:** + - Dice Loss: Only computes intersection/union over masked regions + - BCE Loss: Multiplies loss by mask, averages over masked voxels + - Combined: Applies masking to both components + +## Annotation Statistics + +Typical annotation coverage with default parameters: +- **~2-5% of volume annotated** (very sparse!) +- **~1,000-2,000 annotated spheres** per correction +- **Training is fast** due to focused loss computation + +## Benefits + +1. **Partial Labeling:** You don't need to label the entire volume +2. **Unambiguous:** Background is explicitly labeled (not just "not foreground") +3. **Efficient:** Loss computation focuses on annotated regions +4. **Scalable:** Can annotate at specific points of interest +5. **Trackable:** Datetime stamps allow version control of annotations + +## Example Use Cases + +1. **Correcting Model Errors:** + - Find regions where model fails + - Add background annotations where false positives occur + - Add foreground annotations where false negatives occur + +2. **Refining Boundaries:** + - Add annotations at unclear boundaries + - Label edge cases the model struggles with + +3. **Class Imbalance:** + - Oversample rare structures by adding more foreground points + - Balance training by adjusting point ratios + +## Files + +- `scripts/generate_sparse_corrections.py`:

+## Sparse Workflow Troubleshooting + +**Problem:** Not enough points sampled + +**Solution:** Check that MIN_POINT_DISTANCE isn't too large, or increase the sampling region + +--- + +**Problem:** Annotations too sparse/dense + +**Solution:** Adjust NUM_FOREGROUND/BACKGROUND_POINTS and ANNOTATION_RADIUS + +--- + +**Problem:** Background points not sampled + +**Solution:** Increase BACKGROUND_MAX_DIST or check that mito regions aren't too isolated + +--- + +# Choosing the Right Workflow + +## Use Dashboard Workflow When: + +✅ You want to **correct specific model errors** visually +✅ You need **dense, high-quality annotations** for small regions +✅ You prefer an **interactive, visual editing** experience +✅ You're working with **<10 correction crops** +✅ You want **fast iteration** between annotation and training +✅ You want the finetuned model to **auto-load in Neuroglancer** after training +✅ You want to **iteratively retrain** on the same GPU without restarting jobs + +**Example Use Cases:** +- Fixing false positives/negatives in a specific region +- Refining boundary predictions +- Creating gold-standard training examples +- Quick prototyping of model corrections +- Iterative annotate-train-inspect loops on a single GPU + +## Use Sparse Point Workflow When: + +✅ You need to annotate **large volumes** efficiently +✅ You want **programmatic control** over annotation placement +✅ You're labeling **thousands of points** across the dataset +✅ You can accept **partial annotations** (not every voxel labeled) +✅ You want to **balance foreground/background** systematically + +**Example Use Cases:** +- Labeling at scale across entire datasets +- Systematic sampling of structures +- Class balancing for rare organelles +- Batch correction generation + +## Combining Both Workflows + +You can use both workflows together: + +1. **Generate sparse annotations** programmatically for broad coverage +2. **Create dashboard crops**
