Measure Less, Know More: Self-Supervised Test-Time Feature Acquisition
Quick summary
arXiv:2610.03454v1 Announce Type: cross Abstract: Recent progress in multimodal, high-dimensional learning has enabled foundation models to process heterogeneous, large-scale data. However, at test time, acquiring all features or modalities can be prohibitively costly and often redundant. Sequentially selecting informative modalities is therefore critical, yet challenging when the downstream task or prediction target is unknown. To this end, we introduce ECHO-$k$, a task-agnostic and self-supervised learning principle for modality acquisition: we use a deep model's internal pretrained represen

Why it matters
This is more than a company headline: it shows who controls infrastructure, users and data in the AI value chain. The practical effect will appear in product integration, pricing and delivered capacity.
