摘要:

我们提出了MagNet,一个基于神经网络的多智能体交互模型,发现一个复杂的多智能体系统的动态和预测从观察演变。我们制定了一个多智能体系统作为一个耦合的非线性网络与一般的常微分方程(ODE)为基础的状态演化,并开发了一个神经网络为基础的实现其时间离散化模型。MagNet经过训练,从观察中发现多智能体系统的核心动态,并在线调整以学习特定于智能体的动态参数,以确保即使智能体的物理或关系属性或智能体数量发生变化时也能准确预测。我们在二维空间中的点质量系统上评估MagNet,Kuramoto相位同步动力学和捕食者-群体相互作用动力学表明,与传统的深度学习模型相比,预测精度提高了几个数量级。

英文摘要:

We present the MagNet, a neural network-based multi-agent interaction model to discover the governing dynamics and predict evolution of a complex multi-agent system from observations. We formulate a multi-agent system as a coupled non-linear network with a generic ordinary differential equation (ODE) based state evolution, and develop a neural network-based realization of its time-discretized model. MagNet is trained to discover the core dynamics of a multi-agent system from observations, and tuned on-line to learn agent-specific parameters of the dynamics to ensure accurate prediction even when physical or relational attributes of agents, or number of agents change. We evaluate MagNet on a point-mass system in two-dimensional space, Kuramoto phase synchronization dynamics and predator-swarm interaction dynamics demonstrating orders of magnitude improvement in prediction accuracy over traditional deep learning models.
