Algorithmic Capabilities of Random Transformers

Neural Information Processing Systems

Why is this the case? One possibility is that some aspect of the transformer architecture makes these behaviors easy to learn. Under this hypothesis, transformer models do not implement any useful functionality when initialized; however, their loss landscape is structured such that they can be (computation-and sample-) efficiently optimized for behaviors of interest.


In-Context Symmetries: Self-Supervised Learning through Contextual World Models

Neural Information Processing Systems

Can incorporating context into self-supervised vision algorithms eliminate augmentation-based inductive priors and enable dynamic adaptation to varying task symmetries? This work suggests a positive answer to this question by proposing to enhance the current joint embedding architecture with a finite context -- an abstract representation of a task, containing a few demonstrations that inform about task-specific symmetries, as shown in Figure 2(c).
