CVT-Bench - Synthetic Isolated NSC: leaderboard
Metric: Normalized survival coefficient (NSC): how long correct answers about the same tracked object pair persist across successive viewpoint probes, scaled so 0 is independent answering and 1 the maximum persistence the per-step accuracies allow (averaged over prefixes of 2 to 10 encounters; negative values retained), on the 100 CVT-Synthetic scenes (rendered CLEVR objects, 5,703 questions; relations left, right, front and behind), asked for the spatial relation between two tagged objects from the source view and from counterfactual viewpoints (yaw rotations and a top view), with the scene given as an image, one scene per request (CVT-Isolated); higher is better. Source: arxiv.org. Saturation forecast: Around March 2027. 5 models tracked.
