From Supervised Learning to Contextual Bandits: The Evolution of AI Decision-Making

Towards AI

Supervised Learning: Train once, deploy static model; Contextual Bandits: Deploy once, allow the agent to adapt actions based on content and its corresponding reward. Supervised learning is a staple in machine learning for well-defined problems, but it struggles to adapt to dynamic environments: enter contextual bandits.

Self-Supervised Learning from Images with JEPA

Hacker News

This paper demonstrates an approach for learning highly semantic image representations without relying on hand-crafted data-augmentations. We introduce the Image-based Joint-Embedding Predictive Architecture (I-JEPA), a non-generative approach for self-supervised learning from images.

Towards Automatic Assessment of Self-Supervised Speech Models Using Rank

Machine Learning Research at Apple

This study explores using embedding rank as an unsupervised evaluation metric for general-purpose speech encoders trained via self-supervised learning (SSL). Traditionally, assessing the performance of these encoders is resource-intensive and requires labeled data from the downstream tasks.
