Model Description

Binary classification model for cybersecurity threat detection. The model uses a deep neural network to classify text embeddings as cyber-related or non-cyber content.

Model Architecture

• Input: 768-dimensional embeddings (e.g., from Gemma)
• Hidden Layers: 512 → 256 → 128 neurons
• Output: 1 (binary classification with sigmoid activation)
• Normalization: LayerNorm + BatchNorm
• Activation: ReLU
• Total Parameters: ~557,184

Performance Metrics

• Accuracy: 0.9690
• Precision: 0.6231
• Recall: 0.4441
• AUC: 0.9392
• F1 Score: 0.5186

Usage

import torch
from huggingface_hub import hf_hub_download

# Download model
model_path = hf_hub_download(
    repo_id="kristiangnordby/cyberLabse",
    filename="model.pt"
)

# Load model
checkpoint = torch.load(model_path, map_location='cpu')

# For inference, you'll need the model class definition
# See model_architecture.py in this repo

Training Data

• Training set: ~166K samples
• Validation set: ~25K samples
• Test set: ~41K samples
• Class distribution: ~18% cyber-related, ~82% non-cyber

Intended Use

This model is designed for:

• Cybersecurity content detection
• Filtering cyber-related articles/documents
• Security threat classification

Limitations

• Requires pre-computed embeddings as input
• Trained on specific corpus - may need fine-tuning for other domains
• Performance depends on quality of input embeddings

Training Details

• Optimizer: Adam (lr=0.001, β₁=0.9, β₂=0.999)
• Loss Function: Binary Cross-Entropy
• Batch Size: 512
• Early Stopping: Patience of 15 epochs
• Learning Rate Scheduling: ReduceLROnPlateau (factor=0.5, patience=5)
