Amortizing Maximum Inner Product Search with Learned Support Functions

arXiv:2603.08001v2 Announce Type: replace Abstract: Maximum inner product search (MIPS) is a crucial subroutine in machine learning, requiring the identification of a vector taken within a database (the keys) that best aligns with a given query. We propose amortized MIPS:…

Rift: A Conflict Signature for Deception in Language Models

arXiv:2606.17229v1 Announce Type: new Abstract: A model that lies while knowing the truth is the central case ELK cannot handle with behavioral evaluation alone. We ask whether such deception leaves an internal signature distinguishing it from honest error. Our key…

Time-Series Foundation Model Embeddings for Remaining Useful Life Estimation

arXiv:2606.11990v2 Announce Type: replace Abstract: Remaining Useful Life (RUL) prediction is essential for industrial predictive maintenance, yet many learning-based approaches rely on extensive feature engineering or large labeled datasets to train task-specific sequence models. In this work, we introduce a…

Conditional Local Importance by Quantile Expectations

arXiv:2411.08821v4 Announce Type: replace-cross Abstract: Global variable importance measures are commonly used to interpret the results of machine learning models. Local variable importance techniques assess how variables contribute to individual observations. Current, popular methods, including LIME and SHAP, provide useful…

Rethinking Groups in Critic-Free RLVR

arXiv:2606.17250v1 Announce Type: new Abstract: Reinforcement learning (RL) has become a central paradigm for post-training large language models. Existing critic-free RL methods typically generate a group of rollouts for the same question to estimate value baselines for advantage computation. However,…

Resource-Efficient Variational Quantum Classifier

arXiv:2511.09204v3 Announce Type: replace-cross Abstract: We introduce the unambiguous quantum classifier based on Hamming distance measurements combined with classical post-processing. The proposed approach improves classification performance through a more effective use of ansatz expressivity, while requiring significantly fewer circuit evaluations.…

ProCUA-SFT Technical Report

arXiv:2606.17321v1 Announce Type: new Abstract: Training computer-use agents (CUAs) — models that interact with graphical desktops through screenshots and keyboard/mouse actions — requires large-scale, diverse trajectory data collected in full desktop environments. The largest public resource, AgentNet (22.5K human trajectories),…

In-Context Environments Induce Evaluation-Awareness in Language Models

arXiv:2603.03824v2 Announce Type: replace-cross Abstract: Humans often become more self-aware under threat, yet can lose self-awareness when absorbed in a task; we hypothesize that language models exhibit environment-dependent textit{evaluation awareness}. This raises concerns that models could strategically underperform, or textit{sandbag},…
