A Quantum Approach to Synthetic Minority Oversampling Technique (SMOTE)

Introduction

 In the realm of machine learning, class imbalance remains a significant challenge, often leading to biased models and poor predictive performance. Addressing this issue, a novel solution has been proposed in the form of Quantum-SMOTE, a quantum computing approach inspired by the traditional Synthetic Minority Oversampling Technique (SMOTE).

Quantum-SMOTE: Bridging Quantum Computing and Machine Learning 

Quantum-SMOTE leverages quantum computing techniques to generate synthetic data points, mitigating the problem of class imbalance in datasets. Unlike conventional SMOTE, which relies on K-Nearest Neighbors (KNN) and Euclidean distances to create synthetic instances, Quantum-SMOTE employs quantum processes such as swap tests and quantum rotation. This method enables the generation of synthetic instances from minority class data points without depending on neighbour proximity.

Key Features and Benefits

  1. Hyperparameter Control: Quantum-SMOTE introduces several hyperparameters, including rotation angle, minority percentage, and splitting factor. These parameters provide greater control over the synthetic data generation process, allowing customization to specific dataset requirements.

  2. Handling High-Dimensional Data: The use of a compact swap test allows Quantum-SMOTE to accommodate a large number of features, making it suitable for high-dimensional datasets.

  3. Evaluation on Telecom Churn Dataset: The approach has been tested on a public Telecom Churn dataset and evaluated using two prominent classification algorithms, Random Forest and Logistic Regression. The impact of Quantum-SMOTE was analyzed with varying proportions of synthetic data.

Why Quantum-SMOTE?

The primary advantage of Quantum-SMOTE is its ability to generate synthetic data points without relying on the proximity of neighbours. This flexibility offers a more nuanced approach to tackling class imbalance, potentially leading to more robust and accurate machine-learning models. Furthermore, the introduction of hyperparameters allows for fine-tuning the algorithm to better suit the specific needs of different datasets.

Conclusion

Quantum-SMOTE represents a significant advancement in the field of machine learning, providing a novel quantum approach to addressing class imbalance. By leveraging quantum processes, it offers a more flexible and customizable solution compared to traditional methods. As quantum computing continues to evolve, Quantum-SMOTE could pave the way for more innovative applications in machine learning and data science. By embracing quantum computing techniques, Quantum-SMOTE opens new avenues for effectively managing class imbalance, ultimately leading to better-performing machine learning models.
