A.1 DataStatistics In this section, we provide more details and statistics on the annotated data. As we can see from the histogram, spatial relationships ofobjects wereannotated themost, followedbymulti-agent relationships like "awareofothers" and"looking at". We list all annotated object attributes and their state values in Tab. 1, and visualize their statistics inFig.2. In Figure 1 (right), we plot the number of changes for each object attribute. If no, we assumea1 and a2 is not related.

In this section, we conduct an ablation study analyzing the effects of iterations in our proposed approach. Moreover, we see that as the iterations progress, the 2D landmark prediction error continues to reduce as seen in Figure 1a. The red points represent the frames that were given initial 2D input labels. The colorbar of these scatter plots represents the reprojection error (Eq. Weassume that only asingle object of interest (Chimpanzee in Figure 1is visible in each frame.

A key part of the SpaceX-xAI deal's rationale is to move datacentres - the central nervous system of AI tools - into space. A key part of the SpaceX-xAI deal's rationale is to move datacentres - the central nervous system of AI tools - into space. Why has Elon Musk merged his rocket company with his AI startup? SpaceX's acquisition of xAI creates business worth $1.25tn but whether premise behind deal will work is questioned The acquisition of xAI by SpaceX is a typical Elon Musk deal: big numbers backed by big ambition. As well as extending "the light of consciousness to the stars", as Musk described it, the transaction creates a business worth $1.25tn (£920bn) by combining Musk's rocket company with his artificial intelligence startup.
