将混合系统嵌入连续潜在向量场 / Embedding Hybrid Systems into Continuous Latent Vector Fields
1️⃣ 一句话总结
本文证明,任何n维混合系统都可以被无损地嵌入到一个更高维(大于2n)的连续向量场中,从而将原本不连续的系统转化为可微优化的形式,并据此提出一种基于潜在神经ODE的新方法,仅从时间序列数据就能更准确地学习具有不同几何形态的混合系统。
This work proves that an $n$-dimensional hybrid system can be embedded into an $m$-dimensional Euclidean space equipped with a continuous vector field on its embedded image whenever $m>2n$. This result suggests that an intrinsically discontinuous hybrid system generically admits a continuous extrinsic representation that is well-posed for differentiable optimization. Building on this existence theorem, we show that a latent Neural ODE with consistency loss in both the latent and state space can accurately recover the flow of hybrid systems. Extensive experiments suggest the proposed method outperforms the existing method in learning hybrid systems with varying geometries from only time series data.
