Qwen3VL-8B QLora 4-bit - xView2 Disaster Recognition

🌍 Disaster Recognition Model | 🚨 Emergency Response | 🗣️ Trilingual (EN/JA/ZH)

License

Built with Qwen3-VL | Fine-tuning: 4-bit QLoRA | Framework: LLaMA-Factory | Languages: English, Japanese, Chinese

A multilingual vision-language model fine-tuned from Qwen/Qwen3-VL-8B-Instruct for disaster type recognition using 4-bit QLoRA on the xView2 dataset.

Model Description

This model specializes in identifying disaster types from satellite/aerial imagery. Through LoRA fine-tuning on 55,008 trilingual (English/Japanese/Chinese) disaster images, it learns to accurately classify various disaster types including fires, floods, hurricanes, earthquakes, tsunamis, and volcanic eruptions.

Key Capabilities

🔥 Fire/Wildfire Recognition - Identifies fire disasters from aerial imagery
🌊 Flood Detection - Recognizes flooding disasters from satellite/aerial images
🌀 Hurricane/Wind Damage - Detects wind disasters and hurricane impacts
🏚️ Earthquake Damage - Identifies earthquake-affected areas
🌋 Volcanic Disasters - Recognizes volcanic disaster patterns
🌊 Tsunami Impact - Tsunami disaster identification
🗣️ Trilingual Support - Responds accurately in English, Japanese, and Chinese

Quick Start

What is This Model?

This is a LoRA adapter (not a full model). You need to:

Load the base model: Qwen/Qwen3-VL-8B-Instruct
Apply this LoRA adapter on top of it

Advantage: Only ~22MB adapter download instead of ~8.7GB full model!

bash

git clone https://github.com/hiyouga/LLaMA-Factory.git
cd LLaMA-Factory
pip install -e .

# Ask about disaster type in image
messages = [{"role": "user", "content": "<image>\nWhat type of disaster occurred in this image?"}]
responses = chat_model.chat(messages=messages, images=["disaster_image.png"])
print(responses[0].response_text)  # Output: "Fire disaster"

# Works in Japanese too
messages_ja = [{"role": "user", "content": "<image>\nこの画像ではどのような種類の災害が発生しましたか？"}]
responses_ja = chat_model.chat(messages=messages_ja, images=["disaster_image.png"])
print(responses_ja[0].response_text)  # Output: "火災災害"

# And Chinese
messages_zh = [{"role": "user", "content": "<image>\n这张图片中发生了什么类型的灾害？"}]
responses_zh = chat_model.chat(messages=messages_zh, images=["disaster_image.png"])
print(responses_zh[0].response_text)  # Output: "火灾"

Model Comparison Examples

Comparison between base model and fine-tuned model on disaster type recognition tasks. The following examples demonstrate significant improvements in accuracy and response quality.

Example 1: Fire Disaster (Southern California)

Image: socal-fire_00001128_post_disaster.png

Question (English): "What type of disaster occurred in this image?"

Model	Response
Base Model	"Based on the visual evidence in the image, this appears to be the aftermath of a landslide or rockfall... The debris at the bottom is the key indicator..." ❌ INCORRECT - Misidentified as landslide (acceptable?)
Fine-tuned	"Fire disaster" ✅ CORRECT - Accurate and concise
Ground Truth	"A fire disaster occurred in this image."

Example 2: Flood Disaster (Hurricane Harvey)

Image: hurricane-harvey_00000186_post_disaster.png

Question (English): "What type of disaster occurred in this image?"

Model	Response
Base Model	"The image shows a green algae bloom, which is not a traditional disaster like a hurricane or earthquake, but it can be considered an environmental disaster..." ❌ INCORRECT - Completely misidentified
Fine-tuned	"Flood disaster" ✅ CORRECT
Ground Truth	"A flooding disaster occurred in this image."

Example 3: Flood Disaster (Hurricane Florence)

Image: hurricane-florence_00000145_post_disaster.png

Question (English): "What type of disaster occurred in this image?"

Model	Response
Base Model	"Based on the image provided, there is no visible evidence of a disaster... The scene appears to be a normal, undisturbed landscape." ❌ INCORRECT - Failed to detect disaster
Fine-tuned	"Flooding" ✅ CORRECT
Ground Truth	"A flooding disaster occurred in this image."

Example 4: Wind Disaster (Hurricane Michael) - Japanese

Image: hurricane-michael_00000436_post_disaster.png

Question (Japanese): "この画像ではどのような種類の災害が発生しましたか？"

Model	Response
Base Model	"この画像では洪水が発生したと推測されます..." ❌ INCORRECT - Misidentified as flood
Fine-tuned	"この画像では風災災害が発生しました。" ✅ CORRECT
Ground Truth	"この画像では風災災害が発生しました。"

Example 5: Wind Disaster (Hurricane Michael) - Japanese

Image: hurricane-michael_00000197_post_disaster.png

Question (Japanese): "この画像ではどのような種類の災害が発生しましたか？"

Model	Response
Base Model	"この画像では台風による災害が発生しています。画像に見られるのは、台風の影響で甚大な被害を受けた都市部の衛星写真です..." ⚠️ PARTIALLY CORRECT - Correct but overly verbose (acceptable)
Fine-tuned	"この画像では風災災害が発生しました。" ✅ CORRECT - Accurate and concise
Ground Truth	"この画像では風災災害が発生しました。"

Key Improvements

The fine-tuned model demonstrates significant improvements over the base model:

✅ Accurate Disaster Type Recognition - Correctly identifies specific disaster types
✅ Concise Responses - Provides direct answers without unnecessary verbosity
✅ Eliminated Hallucinations - No longer invents non-existent disaster details
✅ Consistent Multilingual Performance - Reliable across English, Japanese, and Chinese
✅ Reduced Misidentification - Accurately distinguishes between different disaster types

Limitations

Language: Primarily trained on English/Japanese/Chinese; performance on other languages not guaranteed
Domain: Specialized for post-disaster satellite/aerial imagery; may not work on ground-level photos
Disaster Type Coverage: Some disaster types may have limited training samples, affecting recognition accuracy
Quantization: Designed for 4-bit quantization; full precision inference not tested
Geographic Bias: Training data may not cover all geographic regions equally
Model Evaluation: Comprehensive evaluation is ongoing; performance metrics will be updated

Intended Use Cases

✅ Recommended:

Post-disaster satellite/aerial image analysis
Disaster type classification for emergency response
Automated disaster dataset annotation
Multilingual disaster recognition (EN/JA/ZH)
Research on disaster impact assessment

❌ Not Recommended:

Real-time disaster prediction (this is classification, not prediction)
Ground-level disaster assessment (trained on aerial imagery)
Medical emergency classification
Legal/insurance claim decisions without human verification
Fine-grained damage severity assessment (binary disaster type only)

Ethical Considerations

Responsible Use

Human Oversight Required: This model should augment, not replace, human disaster assessment
Verification Needed: All classifications should be verified by disaster response professionals
Not for Sole Decision-Making: Do not use as the only basis for resource allocation or policy decisions
Privacy: Be mindful of privacy when processing imagery that may contain identifiable information
Bias Awareness: Model performance may vary across geographic regions and disaster contexts

Humanitarian Applications

This model is intended to support humanitarian efforts and disaster response. We encourage:

Open collaboration with disaster response organizations
Responsible sharing of insights with affected communities
Transparent communication of model limitations
Continuous improvement based on real-world feedback
