In the evolving world of artificial intelligence, enhancing security systems is paramount. Leveraging machine learning for intrusion detection is one way to safeguard our digital environments. In this blog, we’ll guide you through the steps to train and utilize a tabular classification model based on the UNSW-NB15 dataset for intrusion detection.

Understanding the Dataset

The UNSW-NB15 dataset contains network traffic data that serves as the foundation for our model. It includes various features, which help in detecting anomalies and potential intrusions. Think of the dataset as a collection of profiles—each row is like an individual person, with attributes such as age, occupation, and hobby. By analyzing these profiles, we can categorize whether they belong to a “safe” or “dangerous” group.

Metrics to Evaluate Your Model

In tabular classification, we primarily focus on performance metrics to ensure our model is effective. The two key metrics are:

• Accuracy: This tells us how many instances our model classified correctly out of the total. For our model, the accuracy stands at an impressive 94.88%.
• Loss: This metric measures the difference between the predicted values and the actual values. Our model has a loss value of 0.3645, indicating that it makes fairly accurate predictions overall.

How to Load and Use the Model

Once our model is trained on the UNSW-NB15 dataset, we can easily use it in practical scenarios. Follow these steps:

1. Go to ML Console.
2. Click on “Load Model” to download the pre-trained model.
3. Input your data into the model on the ML Console to predict intrusions in real-time.

Training Your Own Model

For those who wish to train their custom model, you can do so easily on ML Console. Here’s how:

1. Visit ML Console.
2. Upload your dataset in the required format similar to UNSW-NB15.
3. Select the settings and initiate the training process.

After training, you’ll have your model ready for various prediction-related tasks!

Troubleshooting Tips

While working with your classification model, you may encounter some common issues. Here are a few troubleshooting suggestions:

• Model Fails to Load: Ensure you have a stable internet connection and that you are accessing the correct model link.
• Unexpected Predictions: If your model gives inaccurate predictions, double-check the dataset format and values you are using.
• High Loss Value: Consider retraining your model with more epochs or tuning your hyperparameters for better performance.
