Quantum Convolutional Neural Network: A Hybrid Quantum-Classical Approach for Iris Dataset Classification
This is an incremental contribution to hybrid quantum-classical models for supervised learning tasks on a small, real-world dataset.
The paper tackled the problem of classification using a hybrid quantum-classical model, achieving 100% accuracy on the Iris dataset test set at epoch 16.
This paper presents a hybrid quantum-classical machine learning model for classification tasks, integrating a 4-qubit quantum circuit with a classical neural network. The quantum circuit is designed to encode the features of the Iris dataset using angle embedding and entangling gates, thereby capturing complex feature relationships that are difficult for classical models alone. The model, which we term a Quantum Convolutional Neural Network (QCNN), was trained over 20 epochs, achieving a perfect 100% accuracy on the Iris dataset test set on 16 epoch. Our results demonstrate the potential of quantum-enhanced models in supervised learning tasks, particularly in efficiently encoding and processing data using quantum resources. We detail the quantum circuit design, parameterized gate selection, and the integration of the quantum layer with classical neural network components. This work contributes to the growing body of research on hybrid quantum-classical models and their applicability to real-world datasets.
