# Water Conflict Multi-Label Classifier
|
| 24 |
+
|
| 25 |
+
## π¬ Experimental Research
|
| 26 |
+
|
| 27 |
+
> **Note:** This experimental research draws on Pacific Institute's [Water Conflict Chronology](https://www.worldwater.org/water-conflict/), which tracks water-related conflicts spanning over 4,500 years of human history. The work is conducted independently and is not affiliated with Pacific Institute.
|
| 28 |
+
|
| 29 |
+
This model is designed to assist researchers in classifying water-related conflict events.
|
| 30 |
+
|
| 31 |
+
The Pacific Institute maintains the world's most comprehensive open-source record of water-related conflicts, documenting over 2,700 events across 4,500 years of history. This is not a commercial product and is not intended for commercial use.
|
| 32 |
+
|
| 33 |
+
## π± Frugal AI: Training with Limited Data
|
| 34 |
|
| 35 |
+
This classifier demonstrates an intentional approach to building AI systems with **limited data** using [SetFit](https://huggingface.co/docs/setfit/en/index) - a framework for few-shot learning with sentence transformers. Rather than defaulting to massive language models (GPT, Claude, or 100B+ parameter models) for simple classification tasks, we fine-tune small, efficient models (e.g., BAAI/bge-small-en-v1.5 with ~33M parameters) on a focused dataset.
|
| 36 |
|
| 37 |
+
**Why this matters:** The industry has normalized using trillion-parameter models to classify headlines, answer simple questions, or categorize text - tasks that don't require world knowledge, reasoning, or generative capabilities. This is computationally wasteful and environmentally costly. A properly fine-tuned small model can achieve comparable or better accuracy while using a fraction of the compute resources.
|
| 38 |
|
| 39 |
+
**Our approach:**
|
| 40 |
+
- Train on ~600 examples (few-shot learning with SetFit)
|
| 41 |
+
- Deploy small parameter models (e.g., ~33M params) vs. 100B-1T parameter alternatives
|
| 42 |
+
- Achieve specialized task performance without the overhead of general-purpose LLMs
|
| 43 |
+
- Reduce inference costs and latency by orders of magnitude
|
| 44 |
|
| 45 |
+
This is not about avoiding large models altogether - they're invaluable for complex reasoning tasks. But for targeted classification problems with labeled data, fine-tuning remains the professional, responsible choice.
|
| 46 |
|
| 47 |
+
## π Model Description
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| 48 |
|
| 49 |
+
This SetFit-based model classifies news headlines about water-related conflicts into three categories:
|
| 50 |
|
| 51 |
+
- **Trigger**: Water resource as a conflict trigger
|
| 52 |
+
- **Casualty**: Water infrastructure as a casualty/target
|
| 53 |
+
- **Weapon**: Water used as a weapon/tool
|
| 54 |
|
| 55 |
+
These categories align with the Pacific Institute's Water Conflict Chronology framework for understanding how water intersects with security and conflict.
|
| 56 |
|
| 57 |
+
## ποΈ Model Details
|
| 58 |
|
| 59 |
+
- **Base Model**: [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2)

|
| 62 |
+
- **Training samples**: 1200 (sampled from 2937 total training pool)
|
| 63 |
+
- **Test samples**: 519 (held-out, never seen during training)
|
| 64 |
+
- **Training time**: ~2-5 minutes on A10G GPU
|
| 65 |
+
- **Model size**: 23M Parameters, ~90MB
|
| 66 |
+
- **Inference speed**: ~5-10ms per headline on CPU

+
The training code is published as a Python package on PyPI:
|
| 73 |
|
| 74 |
```bash
|
| 75 |
+
pip install water-conflict-classifier
|
| 76 |
```

|
| 83 |
+
|
| 84 |
+
**Source code:** https://github.com/baobabtech/waterconflict/tree/main/classifier
|
| 85 |
+
**PyPI:** https://pypi.org/project/water-conflict-classifier/
|
| 86 |
+
|
| 87 |
+
### Quick Start
|
| 88 |
|
| 89 |
```python
|
| 90 |
from setfit import SetFitModel
|
| 91 |
|
| 92 |
+
# Load the trained model from HF Hub
|
| 93 |
model = SetFitModel.from_pretrained("baobabtech/water-conflict-classifier-minilm")
|
| 94 |
+
|
| 95 |
+
# Predict on headlines
|
| 96 |
+
headlines = [
|
| 97 |
+
"Taliban attack workers at the Kajaki Dam in Afghanistan",
|
| 98 |
+
"New water treatment plant opens in California"
|
| 99 |
+
]
|
| 100 |
+
|
| 101 |
+
predictions = model.predict(headlines)
|
| 102 |
+
print(predictions)
|
| 103 |
+
# Output: [[1, 1, 0], [0, 0, 0]]
|
| 104 |
+
# Format: [Trigger, Casualty, Weapon]
|
| 105 |
```
|
| 106 |
|
| 107 |
+
### Interpreting Results
|
| 108 |
+
|
| 109 |
+
The model returns a list of binary predictions for each label:
|
| 110 |
+
|
| 111 |
+
```python
|
| 112 |
+
label_names = ['Trigger', 'Casualty', 'Weapon']
|
| 113 |
+
|
| 114 |
+
for headline, pred in zip(headlines, predictions):
|
| 115 |
+
labels = [label_names[i] for i, val in enumerate(pred) if val == 1]
|
| 116 |
+
print(f"Headline: {headline}")
|
| 117 |
+
print(f"Labels: {', '.join(labels) if labels else 'None'}")
|
| 118 |
+
print()
|
| 119 |
+
```
|
| 120 |
+
|
| 121 |
+
### Batch Processing
|
| 122 |
+
|
| 123 |
+
```python
|
| 124 |
+
import pandas as pd
|
| 125 |
+
|
| 126 |
+
# Load your data
|
| 127 |
+
df = pd.read_csv("your_headlines.csv")
|
| 128 |
+
|
| 129 |
+
# Predict in batches
|
| 130 |
+
predictions = model.predict(df['headline'].tolist())
|
| 131 |
+
|
| 132 |
+
# Add predictions to dataframe
|
| 133 |
+
df['trigger'] = [p[0] for p in predictions]
|
| 134 |
+
df['casualty'] = [p[1] for p in predictions]
|
| 135 |
+
df['weapon'] = [p[2] for p in predictions]
|
| 136 |
+
```
|
| 137 |
+
|
| 138 |
+

### Training Details
|
| 169 |
+
|
| 170 |
+
- **Training samples**: 1200 examples
|
| 171 |
+
- **Test samples**: 519 examples (held-out before sampling)
|
| 172 |
+
- **Base model**: sentence-transformers/all-MiniLM-L6-v2 (23M params)
|
| 173 |
+
- **Batch size**: 64
|
| 174 |
+
- **Epochs**: 1
|
| 175 |
+
- **Iterations**: 20 (contrastive pair generation)
|
| 176 |
+
- **Sampling strategy**: undersampling (balances positive/negative pairs)
|
| 177 |
+
|
| 178 |
+
### π Experiment Tracking
|
| 179 |
+
|
| 180 |
+
All training runs are automatically tracked in a public dataset for experiment comparison:
|
| 181 |
+
|
| 182 |
+
- **Evals Dataset**: [baobabtech/water-conflict-classifier-evals](https://huggingface.co/datasets/baobabtech/water-conflict-classifier-evals)
|
| 183 |
+
- **Tracked Metrics**: F1 scores, accuracy, per-label performance, and all hyperparameters
|
| 184 |
+
- **Compare Experiments**: View how different configurations (sample size, epochs, batch size) affect performance
|
| 185 |
+
- **Reproducibility**: Full training configs logged for each version
|
| 186 |
+
|
| 187 |
+
You can explore past experiments and compare model performance across versions using the evals dataset.

### Positive Examples (Water Conflict Headlines)
|

### Negative Examples (Non-Water Conflict Headlines)
|

Armed Conflict Location & Event Data Project (ACLED).

+
**Note:** Training negatives include synthetic "hard negatives" - peaceful water-related news (e.g., "New desalination plant opens", "Water conservation conference") to prevent false positives on non-conflict water topics.

## π About This Project
|
| 203 |
+
|
| 204 |
+
This model is part of independent experimental research drawing on the Pacific Institute's Water Conflict Chronology. The Pacific Institute maintains the world's most comprehensive open-source record of water-related conflicts, documenting over 2,700 events across 4,500 years of history.

### Training Your Own Model
|
| 213 |
+
|
| 214 |
+
You can train your own version using the published package:
|
| 215 |
+
|
| 216 |
+
```bash
|
| 217 |
+
# Install package
|
| 218 |
+
pip install water-conflict-classifier
|
| 219 |
+
|
| 220 |
+
# Or install from source for development
|
| 221 |
+
git clone https://github.com/baobabtech/waterconflict.git
|
| 222 |
+
cd waterconflict/classifier
|
| 223 |
+
pip install -e .
|
| 224 |
+
|
| 225 |
+
# Train locally
|
| 226 |
+
