pixtral_aerial_VQA_adapter

Overview

This repository contains a fine-tuned LoRA adapter for the Pixtral-12B model, optimized specifically for aerial imagery analysis and visual question answering. The adapter enables detailed processing of aerial footage with a focus on construction site surveying, structural assessment, and environmental monitoring.

Model Details

• Type: LoRA Adapter
• Total Parameters: 6,225,920
• Memory Usage: 23.75 MB
• Precisions: torch.float32
• Layer Types:
  • lora_A: 40
  • lora_B: 40
• Base Model: mistralai/Pixtral-12B-2409

Capabilities

The adapter enhances Pixtral's ability to:

• Identify and describe construction elements in aerial imagery
• Detect structural issues in buildings and infrastructure
• Analyze progress in construction projects
• Monitor environmental changes and flooding events
• Process high-resolution aerial imagery with improved detail recognition

Intended Use

• Primary intended uses: Processing aerial footage of construction sites for structural and construction surveying.
• Can also be applied to any detailed VQA use cases with aerial footage.
• Suitable for disaster response and assessment applications, particularly flood monitoring.

Training Data

• Dataset:
  1. FloodNet Track 2 dataset
  2. Subset of FGVC Aircraft dataset
  3. Custom dataset of 10 image-caption pairs created using Pixtral

Training Procedure

• Training method: LoRA (Low-Rank Adaptation)
• Base model: Ertugrul/Pixtral-12B-Captioner-Relaxed
• Training hardware: Nebius-hosted NVIDIA H100 machine

Usage Example

from transformers import AutoProcessor, AutoModelForCausalLM
import torch
from PIL import Image

# Load model and processor
model_id = "takara-ai/pixtral_aerial_VQA_adapter"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Load and process image
image = Image.open("path_to_aerial_image.jpg")
prompt = "Describe the construction progress visible in this aerial image."

# Generate response
inputs = processor(text=prompt, images=image, return_tensors="pt").to(model.device)
generated_ids = model.generate(
    **inputs,
    max_new_tokens=512,
    do_sample=True,
    temperature=0.7
)
response = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
