In order to learn a bidirectional mapping between images/text and NeRFS, we train two MLPs, one that maps CLIP image embeddings to \({\tt nf2vec}\) NeRF embeddings, and the other computing the mapping in the opposite direction.

Results
Zero-shot NeRF classification
</h3>

<p class="text-justify">
We first evaluate the feasibility of using \({\tt inr2vec}\) embeddings of INRs
to solve tasks usually tackled by representation learning, and we select 3D
retrieval as a benchmark. Quantitative results, reported in the following table,
show that, while there is an average gap of 1.8 mAP with PointNet++, \({\tt inr2vec}\)
is able to match, and in some cases even surpass, the performance of the other baselines.
