+
+## Classes
+
+This dataset uses multi-label classification, meaning each image can have multiple class labels.
+
+The dataset contains the following classes:
+
+- **rah** (0): Rock Abrasion Tool (RAT) Hole
+- **cla** (1): Clasts
+- **dur** (2): Dunes/Ripples
+- **soi** (3): Soil
+- **roc** (4): Rock Outcrops
+- **clr** (5): Close-up Rock
+- **rab** (6): Rock Abrasion Tool (RAT) Brushed Target
+- **div** (7): Distant Vista
+- **rod** (8): Rover Deck
+- **bso** (9): Bright Soil
+- **flr** (10): Float Rocks
+- **art** (11): Artifacts
+- **pct** (12): Pancam Calibration Target
+- **arh** (13): Arm Hardware
+- **rrf** (14): Rock (Round Features)
+- **sph** (15): Spherules
+- **ohw** (16): Other Hardware
+- **ast** (17): Astronomy
+- **nbs** (18): Nearby Surface
+- **rmi** (19): Rocks (Misc)
+- **rtr** (20): Rover Tracks
+- **sky** (21): Sky
+- **rpa** (22): Rover Parts
+- **rlf** (23): Rock (Linear Features)
+- **sot** (24): Soil Trench
+## Statistics
+
+- **train**: 1762 images
+- **val**: 443 images
+- **test**: 739 images
+- **few_shot_train_10_shot**: 1310 images
+- **few_shot_train_15_shot**: 1357 images
+- **few_shot_train_1_shot**: 1198 images
+- **few_shot_train_20_shot**: 1402 images

+
+## Few-shot Splits
+
+This dataset includes the following few-shot training splits:
+
+- **few_shot_train_10_shot**: 1310 images
+- **few_shot_train_15_shot**: 1357 images
+- **few_shot_train_1_shot**: 1198 images
+- **few_shot_train_20_shot**: 1402 images
+- **few_shot_train_2_shot**: 1212 images
+- **few_shot_train_5_shot**: 1249 images
+
+Few-shot configurations:
+
+- **10_shot.csv**
+- **15_shot.csv**
+- **1_shot.csv**
+- **20_shot.csv**
+- **2_shot.csv**
+- **5_shot.csv**
+## Format
+
+Each example in the dataset has the following format:
+
+```
+{
+  'image': Image(...),  # PIL image
+  'labels': List[int],  # Multi-hot encoded binary vector (1 if class is present, 0 otherwise)
+  'feature_names': List[str],  # List of feature names (class short codes)
+}
+```
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("gremlin97/mars-multi-label-classification")
+
+# Access an example
+example = dataset['train'][0]
+image = example['image']  # PIL image
+labels = example['labels']  # Multi-hot encoded binary vector
+
+# Example of how to find which classes are present in an image
+present_classes = [i for i, is_present in enumerate(labels) if is_present == 1]
+print(f"Classes present in this image: {present_classes}")
+```
+
+## Multi-label Classification
+
+In multi-label classification, each image can belong to multiple classes simultaneously. The labels are represented as a binary vector where a 1 indicates the presence of a class and a 0 indicates its absence.
+
+Unlike single-label classification where each image has exactly one class, multi-label classification allows modeling scenarios where multiple features can be present in the same image, which is often the case with Mars imagery.
