This paper proposes an efficient quantum train engine (EQuaTE), a novel tool for quantum machine learning software which plots gradient variances to check whether our quantum neural network (QNN) falls into local minima (called barren plateaus in QNN). EQuaTE can be realized via dynamic analysis of the undetermined probabilistic qubit states. Furthermore, the proposed EQuaTE is capable of HCI-based visual feedback such that software engineers can recognize barren plateaus via visualization, allowing the modification of QNN based on this information.
V. CONCLUDINGREMARKS This paper proposes a novel QML software tool which visually plots gradient variances to check for the occurrence of barren plateaus via dynamic analysis, called EQuaTE. Furthermore, our EQuaTE is capable for visual feedback because it allows software engineers to modify QNNs based on the recognized barren plateaus using tensorboard. Acknowledgement.
