ConflLlama: GTD-Finetuned LLaMA-3 8B

• Model Type: GGUF quantized (q4_k_m and q8_0)
• Base Model: unsloth/llama-3-8b-bnb-4bit
• Quantization Details:
  • Methods: q4_k_m, q8_0, BF16
  • q4_k_m uses Q6_K for half of attention.wv and feed_forward.w2 tensors
  • Optimized for both speed (q8_0) and quality (q4_k_m)

Training Data

• Dataset: Global Terrorism Database (GTD)
• Time Period: Events before January 1, 2017
• Format: Event summaries with associated attack types
• Labels: Attack type classifications from GTD

Data Processing

1. Date Filtering:
   • Filtered events occurring before 2017-01-01
   • Handled missing dates by setting default month/day to 1
2. Data Cleaning:
   • Removed entries with missing summaries
   • Cleaned summary text by removing special characters and formatting
3. Attack Type Processing:
   • Combined multiple attack types with separator '|'
   • Included primary, secondary, and tertiary attack types when available
4. Training Format:
   • Input: Processed event summaries
   • Output: Combined attack types
   • Used chat template:

Model Architecture

The model uses a combination of efficient fine-tuning techniques and optimizations for handling conflict event classification:

Data Processing Pipeline

The preprocessing pipeline transforms raw GTD data into a format suitable for fine-tuning:

Memory Optimizations

• Used 4-bit quantization
• Gradient accumulation steps: 8
• Memory-efficient gradient checkpointing
• Reduced maximum sequence length to 1024
• Disabled dataloader pin memory

Intended Use

This model is designed for:

1. Classification of terrorist events based on event descriptions
2. Research in conflict studies and terrorism analysis
3. Understanding attack type patterns in historical events
4. Academic research in security studies

Limitations

1. Training data limited to pre-2017 events
2. Maximum sequence length limited to 1024 tokens
3. May not capture recent changes in attack patterns
4. Performance dependent on quality of event descriptions

Ethical Considerations

1. Model trained on sensitive terrorism-related data
2. Should be used responsibly for research purposes only
3. Not intended for operational security decisions
4. Results should be interpreted with appropriate context
