The paper introduces iAmTime, a time‑series foundation model that uses instruction‑conditioned in‑context learning to adapt to tasks at inference time. iAmTime represents each episode as a structured prompt with semantic tokens that focus on specific time‑series regions, enabling the model to infer task structure from input‑output demonstrations. Trained on large real and synthetic corpora across forecasting, imputation, reconstruction, classification, anomaly detection, and source de‑mixing, iAmTime outperforms strong baselines on zero‑shot probabilistic and point forecasting while matching or exceeding performance on several non‑forecasting tasks.

The paper introduces a sentence‑level benchmark for judging large language models’ ability to classify interpretive canons used by the German Federal Constitutional Court, based on Larenz’s framework. It operationalizes these canons as classification criteria, provides a dataset of court decisions annotated at the sentence level, and evaluates four LLMs with both expert hand‑written prompts and prompts optimized via Genetic‑Pareto. The results show mean F1 scores between 70.4 and 79.2, with grammatical interpretation being the easiest and systematic interpretation the hardest, and indicate that expert prompts already offer a strong baseline.

The paper introduces WebMRE, an offline benchmark comprising 541 tasks and 5,293 steps extracted from WebArena trajectories, designed to provide deterministic scoring for web agents without live environments. It enables the first systematic study of how guide sentences and grounded actions reinforce each other, showing that jointly decoding a guide improves element selection accuracy and that the guide acts as a causal instruction channel. The authors fine‑tune models that outperform leading zero‑shot baselines on all offline metrics.

The paper introduces RoPA Manager, a system that automates the extraction of Records of Processing Activities (RoPA) required by Vietnam’s new Personal Data Protection Law. It combines hybrid retrieval techniques—lexical ranking, dense‑vector search, and Reciprocal Rank Fusion—with locally deployed large language models to avoid data‑sovereignty issues. A Vietnamese RoPA benchmark of 32 organizations and 77 processing activities was created, and the system achieved robust scorer performance (F1 ≈ 0.95) and moderate end‑to‑end token coverage (≈ 50‑55%).

EviStreams is a live, open‑source, no‑code web platform that enables systematic review teams to control AI‑assisted data extraction at three stages: program design, field specification, and extracted predictions. Reviewers use a form builder to define typed fields, run extraction on PDFs, inspect AI‑generated values with supporting passages, and perform blinded dual review with adjudication to produce an auditable consensus export. An evaluation across four clinical corpora and three model families shows that extraction quality depends more on field specification than on the model choice.

The paper compares Jev with nine language models on the ContractNLI task, assessing inference cost, response time, average correctness, and correctness under repeated requests. Controlled experiments vary hypothesis visibility, requested outputs, and output order while keeping the contract and target judgment fixed. Jev achieves the lowest cost and median response time, whereas hosted language models show higher baseline accuracy, but rankings differ when evaluating correctness across all conditions and repeats.

The study examines how teenagers discuss and navigate generative AI in their daily lives, using data from r/teenagers between January 2023 and July 2026. Analysis of 11,083 posts identified eight interconnected domains of experience, with everyday and social use being most common. Over time, discussions shifted toward concerns about authenticity, personal control, safety, and the future role of humans versus AI, highlighting adolescents’ active negotiation of AI’s place in their lives.

The paper introduces Selective Prefix Anti-Interference Regularization (SPAR), a pretraining objective that trains language models to ignore irrelevant distant prefixes. SPAR compares predictions from the original sequence with those from a corrupted prefix that only alters far tokens, using a sufficiency gate and a gated KL loss to stabilize suffix predictions that are already locally supported. Experiments show that SPAR improves robustness metrics such as RULER and NoLiMa across several models, including Qwen2.5, Llama, and GPT2-XL, under equal compute.

The paper introduces Self‑Conditioning, an unsupervised, information‑theoretic estimator that measures the amount of external information in peer reviews. It compares the likelihood of a review under its original production context with the likelihood when that context is augmented by hints extracted from the review itself. On the IntelLabs benchmark, Self‑Conditioning can perfectly distinguish fully‑delegated reviews from machine‑polished ones, remains largely insensitive to surface rewriting, and shows that increased external input drives scores toward human‑like values, unlike standard ATD baselines.

The paper investigates how large language models use activation memory (KV caches) and parametric memory (updated parameters) during few‑shot learning. Experiments show activation memory excels at factual recall, while parametric memory does not consistently outperform it for task learning. The composite task Conditional Arithmetic requires both memory types, with neuron‑level analysis revealing distinct neuron sets activated by each memory, and their combined use is essential for success.

The paper introduces Causal Shortcut Learning (CSL), a framework that identifies token chains—called causal shortcuts—that guide Diffusion Language Models (DLMs) toward correct reasoning paths. By extracting these shortcuts and applying parallel prioritized masking during training, CSL improves both convergence speed and generation accuracy. Experiments on several reasoning benchmarks and two base models show CSL outperforms existing SFT-variant baselines, achieving an average 1.92% improvement over SFT-only models and up to 4.20% on MATH-500.

The paper argues that meaning identity—whether two sentences convey the same idea after wording changes—is not encoded in the geometry of independently produced sentence embeddings. Experiments on frozen off‑the‑shelf encoders and language models show that identity can only be reliably computed when both sentences are processed together in a single forward pass, yielding high accuracy (0.90–0.96) on PAWS‑X, whereas independent embeddings or simple fusion methods perform near chance. Even advanced bi‑encoder fine‑tuning improves performance on PAWS but fails to generalize to other similarity tasks, underscoring that identity is a cheap computed operator rather than a property of individual sentence vectors.

RapidUn is a parameter reweighting framework that uses influence estimates to guide LoRA-only updates for efficient unlearning of targeted behaviors in large language models. It operates in a practical PEFT setting with a small forget set and limited retain buffer, converting cross-sample influence into fixed sample-specific weights for weighted LoRA unlearning. Experiments on Llama‑3‑8B with Dolly‑15k and Alpaca‑57k datasets show RapidUn achieves lower trigger ASR than Fisher, GA, and LoReUn while preserving clean utility, and delivers a 77× wall‑clock speedup over clean‑corpus LoRA retraining, with additional evaluations supporting its effectiveness.

SafeTutors is a benchmark designed to evaluate both safety and pedagogical effectiveness of AI tutoring systems across mathematics, physics, and chemistry. It introduces a risk taxonomy of 11 harm dimensions and 48 sub‑risks based on learning‑science literature, focusing on issues such as answer over‑disclosure, misconception reinforcement, and loss of scaffolding. The study finds that all tested models exhibit broad harms, that larger scale does not mitigate these issues, and that multi‑turn interactions significantly increase pedagogical failures from 17.7% to 77.8%.

The paper investigates when vision‑language models (VLMs) can independently analyze human‑centered video and when human oversight is still needed. By reviewing 1,702 CHI 2026 papers, the authors develop a five‑dimensional taxonomy of video annotation tasks and build a benchmark of 15 representative tasks. Experiments show that VLMs alone achieve near‑human accuracy (HNS = 97.0), while human verification of VLM outputs yields the highest accuracy (HNS = 121.5) and significantly reduces annotation time and cost.

DualStabSleepNet (DSSNet) is a dual-domain diffusion stabilization network designed to improve the robustness of automatic sleep staging across heterogeneous recording conditions. It employs a continuous-scale diffusion-based module to suppress noise while preserving physiological signals, then transforms stabilized signals into time-frequency representations for a Vision Transformer backbone. A teacher‑student guided diffusion feature stabilization further reduces feature drift, achieving state‑of‑the‑art accuracy on four public PSG datasets and demonstrating strong performance under cross‑dataset distribution shifts.

The paper introduces a modular perception framework that uses vision‑language models (VLMs) to annotate object‑level regions from a single RGB‑D observation, then grounds these annotations with depth data to build an object‑centric representation. Experiments on 151 tabletop scenes demonstrate that this decomposition maintains strong semantic performance while significantly improving localization and depth estimation compared to direct VLM inference. The resulting representation is integrated into a task‑planning system for robotic manipulation.
