Researchers have developed KOALA, a new framework for predicting human motion using WiFi Channel State Information (CSI). Unlike previous methods that treat pose inference as an instantaneous problem, KOALA models temporal dynamics by mapping noisy CSI-derived pose sequences into a Koopman latent space. This transformation linearizes the system's nonlinear dynamics, allowing for multi-horizon predictions through simple matrix-vector products without iterative error accumulation. The framework incorporates a residual CSI-conditioned operator to address the identity attractor problem and an anchor-delta prediction head to prevent degenerate shortcuts. Experiments on MM-Fi and WiPose datasets demonstrate KOALA's superior performance in both short- and long-term motion prediction. AI
