1. Apple Amortizes Maximum Inner Product Search With Learned Support Functions

Apple researchers propose training a neural network to predict solutions to maximum inner product search directly, amortizing a cost that normally scales with the size of the candidate set. The approach targets retrieval and recommendation workloads where MIPS is a bottleneck, trading upfront training for faster query-time lookups. Source

2. Apple Introduces Ctrl-R for Structured Reasoning via Trajectory Control

Apple presents Ctrl-R, a framework that steers language models to discover diverse reasoning patterns through structured exploration of the trajectory space rather than a single decoding path. The method aims to make reasoning both more controllable and more varied, which matters for tasks where a model can reach the right answer through several distinct chains. Source

3. Apple Learns Unmasking Policies for Diffusion Language Models

Apple studies how diffusion language models decide which tokens to unmask at each step, replacing hand-tuned heuristics with a learned policy. The paper reports that learned unmasking order improves generation quality over fixed schedules, addressing one of the practical weak points of diffusion-based text generation. Source

4. Apple Proposes Residual Context Diffusion Language Models

Apple describes a diffusion language model that recycles token computation normally discarded between decoding iterations, retaining contextual information for later steps. The residual-context design is meant to reduce wasted compute and preserve signal across the iterative denoising process. Source

5. Apple Examines Anti-Causal Domain Generalization With Unlabeled Data

Apple investigates domain generalization in anti-causal settings, where the label determines the observed features rather than the reverse, and shows how unlabeled target data can be leveraged to adapt. The work targets robustness when models are deployed on distributions that differ from their training data. Source
