论文摘要
先前的工作表明,在处理时间相关的输入(例如无线通信信号)时,反复的神经网络体系结构比其他机器学习体系结构显示出有希望的改进。此外,复发性神经网络通常按顺序处理数据,从而有可能获得近实时结果。在这项工作中,我们研究了“足够”决策的新颖用法,以根据可变数量的输入符号在推理期间做出决策。由于某些信号比其他信号更复杂,因此由于通道条件,发射器/接收器效应等,能够动态地利用足够的接收符号来做出可靠的决策,从而可以在应用程序中更有效地决策,例如电子战和动态频谱共享。为了证明这一概念的有效性,在这项工作中考虑了四种做出“足够”决定的方法,并分析了每个方法的适用性,以适用于无线通信机器学习应用程序。
Prior work has demonstrated that recurrent neural network architectures show promising improvements over other machine learning architectures when processing temporally correlated inputs, such as wireless communication signals. Additionally, recurrent neural networks typically process data on a sequential basis, enabling the potential for near real-time results. In this work, we investigate the novel usage of "just enough" decision making metrics for making decisions during inference based on a variable number of input symbols. Since some signals are more complex than others, due to channel conditions, transmitter/receiver effects, etc., being able to dynamically utilize just enough of the received symbols to make a reliable decision allows for more efficient decision making in applications such as electronic warfare and dynamic spectrum sharing. To demonstrate the validity of this concept, four approaches to making "just enough" decisions are considered in this work and each are analyzed for their applicability to wireless communication machine learning applications.
