Hybrid quantum inception-inspired convolutional neural network for image classification
摘要
Quantum Neural Networks (QNNs) present a promising research direction in image recognition. However, models that rely on a single circuit topology frequently exhibit limited expressive capacity, thereby constraining scalability and recognition accuracy. To address these limitations, we propose a Hybrid Quantum–Classical Inception-Inspired Convolutional Neural Networks (HQICNN). The specific descriptions are as follows. First, in the encoding layer, amplitude encoding layer is adopted to map complete multi-channel images data into quantum states. Second, in the convolutional layer, this architecture utilizes quantum convolutional kernels with heterogeneous circuit topologies for feature extraction. A Hadamard integration method is proposed to aggregate multi-channel feature information. Then, in the pooling layer, quantum pooling using RY gates is employed to reduce feature dimensionality. Finally, in the prediction layer, a fully connected layer is applied to map the quantum-enhancing features into class labels for classification tasks. The quantum resource analysis indicates that for the MNIST-4 classification task, the quantum circuit depth of the proposed HQICNN is approximately O(n), which is lower to the existing HQCNN model(
