Inertia-1: An Open Exploration to a Unified Motion Foundation Model

📝 Discussion Summary (Click to expand)

Temporal Consistency Challenges: Handling continuity and noise in motion models is critical, especially with sparse data. "Handling continuity and temporal consistency in these models is always the hardest part, especially when dealing with noise or sparse data over time" (myshapeprotocol)
Long-Trajectory Drift: State verification must address drift accumulation in extended sequences. "state verification handles drift across long trajectories" (myshapeprotocol)
Sparse Data Impact: Insufficient data directly exacerbates noise issues. "noise or sparse data" (myshapeprotocol)
