Process-based catchment model matches deep-learning accuracy across three continents

A new process-based hydrological model, CaRT+, built on physical laws and refined with AI assistance, achieves accuracy comparable to LSTM neural networks on catchments in Britain, the US, and Australia. With 35 parameters per catchment and no daily neural network, it reaches median Nash-Sutcliffe efficiencies of 0.863 and 0.765 in held-out years on British and US data, and outperforms LSTMs on Australian catchments. The results suggest that catchment-scale laws exist as laws of form, with shared constitutive families and only parameters learned.

Why it matters: This is a concrete, recent research result showing a process-based model matching deep learning accuracy, with implications for hydrology and AI-assisted model refinement.

Robust Closed-Loop LLM Steering Inspired by Neurostimulation

This paper frames LLM steering as a feedback-control problem, using the network's internal state to condition interventions, inspired by closed-loop neurostimulation. It introduces an H-infinity-based controller that explicitly handles model mismatch and disturbances, improving performance over baselines, especially in out-of-distribution settings. The authors also propose a pre-deployment measure, robust steerability, to quantify tolerance to dynamics mismatch.

ArcRAG: Agentic Compositional Retrieval over Knowledge Graphs

ArcRAG introduces a query-time interface induction method that makes retrieval over knowledge graphs portable across different graph constructions. It builds a local graph interface from entities mentioned in a question)Skip planning multi-hop traversals and executing them as Cypher, without needing construction-specific schema or retuning. Experiments on MuSiQue, HotpotQA, and TriviaQA show that this construction-agnostic retriever remains effective across schema-guided and open-information-extraction graphs, though absolute accuracy still depends on construction.

Model Merging Does Not Require Uniform LoRA Ranks

This paper challenges the standard practice of using uniform LoRA ranks across experts in model merging. Experiments with 36 experts across three domains and multiple scales show that assigning per-domain best ranks can improve multi-domain accuracy by up to 1.8 percentage points with averaging and utility-based methods, while magnitude-based conflict-resolution methods suffer. The authors identify that magnitude-based component selection discards useful spectral components and can drop entire experts, causing large performance drops.

Why it matters: Provides concrete evidence and a practical insight that can improve model merging efficiency and accuracy, relevant to AI practitioners.

IDSISA: Influence-Distilled Sharded Training for Efficient Machine Unlearning

IDSISA improves SISA-based machine unlearning by using influence functions to concentrate forget-prone samples into fewer shards, reducing retraining overhead, and applying distillation from unaffected shards to recover utility lost to isolation. It preserves SISA's exact deletion guarantee and adds a bounded approximation for utility recovery, with formal handling of repeated deletion sequences via cascading retraining. Experiments across multiple architectures show 14-91% better selective forgetting and up to 50% relative utility retention gains over SISA.

Online Rubric Self-Distillation for Token-Level Credit Assignment in RL

The paper introduces ORSD, a method that generates natural-language process rubrics from on-policy trajectories to provide dense token-level supervision for reinforcement learning. A frozen verifier selects the best rubric bundle based on alignment with task success, and the likelihood gap with and without the rubric yields token-specific credit added to trajectory-level advantages. Experiments on ALFWorld and WebShop show faster policy improvement and higher final performance for Qwen3-1.7B and Qwen3-4B.

Why it matters: This is a novel, concrete AI research contribution with empirical results, addressing a key challenge in RL credit assignment.

Addition by Subtraction: Mitigating Fragile Safety Alignment in LLMs

This paper introduces Addition by Subtraction, a finetuning method that removes safety-critical neurons and uses preference optimization to redistribute safety behavior across the model. The resulting models are significantly more robust to pruning-based attacks, refusal-direction ablation, and various black-box jailbreaks, with attack success rates reduced by up to 90% across four models. The approach also improves truthfulness while largely preserving general capabilities.

One Scale, Four Texts: Gaps, Overlaps and Silent Repairs in Published Grading Schemes

This paper analyzes four published texts of the diabetic retinopathy grading scale, formalizing them into a rule language and exhaustively enumerating 1.4 billion finding profiles. It reveals that every text leaves some eyes uncategorized, the 2017 tabulation has an empty proliferative class and a macular gap absent in 2003, and English and Italian texts order some eyes oppositely. On 927 annotated photographs, the English text and 2017 tabulation disagree on referral for 26.8% of DDR eyes, and classifiers trained on each text's labels side with their own text. A second pre-registered study shows language models often silently repair gaps and overlaps, with Claude models reporting defects more often.

Why it matters: Provides concrete, quantified evidence of inconsistencies in real-world grading schemes, with implications for AI training and deployment in medical imaging.

Germline Execution Blocks Data Exfiltration in Signed MCP Tools

This paper demonstrates that authenticated MCP tools can hide malicious code that leaks data, bypassing runtime defenses like Meta's MCPGuard-Dynamic. The authors introduce germline execution, which runs each tool invocation in an ephemeral copy forked from a data-free process, limiting disclosure to only authorized data. In 153 attack runs, germline execution prevented all unauthorized disclosures, while baseline defenses failed in 5.9-74.5% of runs, with invocation latency of 10-49 ms.

Why it matters: Provides a novel, proven defense against a critical security flaw in AI agent toolchains, with concrete experimental results and formal guarantees.
