Quantum-Inspired Neural Networks Outperform Traditional Models in Stock Prediction

arXiv CS.AI

In brief

  • Researchers have developed a new type of machine learning model that uses quantum-inspired techniques to predict stock prices more accurately and efficiently than traditional methods.
  • The study compares three types of models-classical artificial neural networks (ANNs), quantum qubit-based neural networks (QQBNs), and quantum qutrit-based neural networks (QQTNs).
  • All models achieved high accuracy, but the QQTN model stood out by consistently performing better in key areas like risk-adjusted returns, prediction consistency, and adaptability to changing market conditions.
  • The QQTN model not only matched or surpassed the performance of its classical and qubit-based counterparts but also required less training time.
    • This efficiency is crucial for financial applications where real-time processing is essential.
  • The findings highlight the potential of quantum-inspired approaches in tackling complex, data-intensive tasks like stock prediction, suggesting a promising future for integrating these models into practical financial systems.

Terms in this brief

Quantum qubit-based neural networks
A type of machine learning model inspired by quantum computing principles, using qubits to potentially solve complex problems more efficiently than classical models. These networks leverage quantum properties for enhanced processing capabilities.
Quantum qutrit-based neural networks
An advanced form of quantum-inspired neural networks that use qutrits—quantum states with three possible values instead of the usual two in qubits. This allows for more nuanced computations and can lead to improved performance in certain tasks, like stock prediction.
