摘要:

本文应用量子机器学习技术来预测移动无线网络中的移动用户的轨迹使用的方法称为量子储备池计算(QRC)。移动用户的轨迹预测属于时间信息处理的任务,是自组织自治6G网络中必不可少的移动性管理问题。我们的目标是准确地预测移动用户在无线网络中使用QRC的未来位置。为此,我们使用真实世界的时间序列数据集来建模移动用户的轨迹。QRC方法有两个组成部分:储备池计算(RC)和量子计算(QC)。在RC中,训练比简单的递归神经网络(RNN)的训练更具计算效率,因为在RC中,只有输出层的权重是可训练的。钢筋混凝土的内部部分是所谓的水库。为了使RC表现良好,应仔细选择水库的权重,以创建高度复杂和非线性的动态。QC用于创建这样的动态库,该动态库将输入时间序列映射到由动态状态组成的高维计算空间。在获得高维动态状态后,进行简单的线性回归来训练输出权重,从而可以有效地执行移动用户轨迹的预测。在本文中,我们应用QRC方法的基础上的哈密顿时间演化的量子系统。我们使用基于IBM门的量子计算机模拟时间演化,并在实验结果中表明,使用QRC来预测移动用户的轨迹只有几个量子比特是有效的,并且能够优于经典的方法,如长短期记忆(LSTM)方法和回声状态网络(ESN)方法。

英文摘要:

This paper applies a quantum machine learning technique to predict mobile users' trajectories in mobile wireless networks using an approach called quantum reservoir computing (QRC). Mobile users' trajectories prediction belongs to the task of temporal information processing and it is a mobility management problem that is essential for self-organizing and autonomous 6G networks. Our aim is to accurately predict the future positions of mobile users in wireless networks using QRC. To do so, we use a real-world time series dataset to model mobile users' trajectories. The QRC approach has two components: reservoir computing (RC) and quantum computing (QC). In RC, the training is more computational-efficient than the training of simple recurrent neural networks (RNN) since, in RC, only the weights of the output layer are trainable. The internal part of RC is what is called the reservoir. For the RC to perform well, the weights of the reservoir should be chosen carefully to create highly complex and nonlinear dynamics. The QC is used to create such dynamical reservoir that maps the input time series into higher dimensional computational space composed of dynamical states. After obtaining the high-dimensional dynamical states, a simple linear regression is performed to train the output weights and thus the prediction of the mobile users' trajectories can be performed efficiently. In this paper, we apply a QRC approach based on the Hamiltonian time evolution of a quantum system. We simulate the time evolution using IBM gate-based quantum computers and we show in the experimental results that the use of QRC to predict the mobile users' trajectories with only a few qubits is efficient and is able to outperform the classical approaches such as the long short-term memory (LSTM) approach and the echo-state networks (ESN) approach.
