# Anomaly Detection Suite
|
| 6 |
+
|
| 7 |
+
This repository hosts a comprehensive project on anomaly detection, evaluating and comparing multiple algorithms on a synthetic dataset. It includes the implementation notebook, trained models, results, and visualizations.
|
| 8 |
+
|
| 9 |
+
## Project Overview
|
| 10 |
+
|
| 11 |
+
This project provides a hands-on guide to identifying outliers using the following methods:
|
| 12 |
+
|
| 13 |
+
- **Statistical Methods (Z-score)**
|
| 14 |
+
- **Isolation Forest**
|
| 15 |
+
- **One-Class SVM**
|
| 16 |
+
- **Local Outlier Factor (LOF)**
|
| 17 |
+
- **Autoencoder (Deep Learning)**
|
| 18 |
+
|
| 19 |
+
The goal is to provide a clear comparison of how these different techniques perform on the same dataset.
|
| 20 |
+
|
| 21 |
+
## Repository Contents
|
| 22 |
+
|
| 23 |
+
- `implementation.ipynb`: The main Jupyter notebook with all the code and explanations.
|
| 24 |
+
- `anomaly_detection_results/`: A directory containing all the generated files:
|
| 25 |
+
- Trained models for each algorithm.
|
| 26 |
+
- Anomaly scores and predictions.
|
| 27 |
+
- Performance metrics and results in JSON format.
|
| 28 |
+
- Visualizations comparing the different methods.
|
| 29 |
+
|
| 30 |
+
## How to Use the Models
|
| 31 |
+
|
| 32 |
+
The trained models are saved in the `anomaly_detection_results/` directory. You can load them to make predictions on new data. For example, to load the Isolation Forest model:
|
| 33 |
+
|
| 34 |
+
```python
|
| 35 |
+
import pickle
|
| 36 |
+
|
| 37 |
+
with open('anomaly_detection_results/isolation_forest_model.pkl', 'rb') as f:
|
| 38 |
+
model = pickle.load(f)
|
| 39 |
+
|
| 40 |
+
# Now you can use the model to predict on new data
|
| 41 |
+
# predictions = model.predict(new_data)
|
| 42 |
+
```
|
| 43 |
+
|
| 44 |
+
## Dataset
|
| 45 |
+
|
| 46 |
+
The dataset is synthetically generated within the `implementation.ipynb` notebook. It consists of two-dimensional data with a clear cluster of normal points and a few scattered outliers.
