Kenneth and Shwetha were in a live-in relationship and had plans of starting a cloud kitchen venture. (Image: File) New Delhi,UPDATED: Jul 22, 2026 11:09 IST Written By: Avinash Kateel Every crime has a mastermind. Every mastermind has a confidant. According to Bengaluru Police, Kenneth's confidant in the triple murder he committed was not another person. It was an AI chatbot. Kenneth (25) consulted the AI chatbot at almost every stage of planning for nearly six months, which he finally turned into reality on June 22 after allegedly killing the parents and younger sister of his live-in partner, Shwetha, in Bengaluru's KR Puram area on June 22, police sources told India Today TV.

This paper investigates how the geometry of the initial set, dynamics, and sampling distribution affect the accuracy of sampling-based reachability analysis. By formulating the problem as geometric support estimation, the authors identify two regularity conditions—positive reach of the initial set's complement and Lipschitz continuity of the dynamics—that allow a probability-mass coverage guarantee to be upgraded to Hausdorff distance accuracy. The sample complexity scales exponentially with state dimension and time horizon, and this exponential dependence is intrinsic, not an artifact of the method. Experiments on nonlinear systems confirm that adversarial sampling improves constants but not the scaling.

Accepted at VTC2026-Fall.

Vision-language-action (VLA) models show impressive generalization but often lack interpretability and struggle with precise natural language instructions involving spatial, temporal, and logical constraints. This paper proposes a hierarchical framework using Signal Temporal Logic (STL) as a shared representation between high-level language understanding and low-level robot execution. The high-level policy uses a VLM to decompose instructions into subtasks, generates STL specifications, and selects low-level policies. STL constraints are enforced via model-predictive control or monitored during execution. Evaluated on a real-world tabletop domain, the framework improves precision, reliability, and interpretability of language-conditioned robot planning.

Vision-Language Models (VLMs) often confuse anomalies with hazards, as current binary safe/unsafe evaluations fail to differentiate true physical dangers from unusual scene elements. This research introduces an explicit hazard vs. anomaly distinction, evaluating multiple VLMs across datasets. Results show VLMs frequently misinterpret anomalousness as hazardous, relying on contextual irregularity as a proxy for danger. Separating the two provides more informative safety reasoning evaluations, exposing failure modes obscured by binary judgments. A public dataset is available on Roboflow.

A new study reveals that requesting JSON format output from language models dramatically reduces answer diversity. Testing 44 models on 31 broad questions, the JSON request increased the modal answer from 41% to 64% and reduced distinct answers. The effect is specific to formats like JSON and XML, and not due to decoder enforcement, indicating that the convergence stems from the model's response to the register.

PathReportEval is a standardized benchmark and evaluation framework for pathology report generation from whole-slide images. It evaluates four methods on three datasets (TCGA, HistAI, REG 2025) using three pathology foundation encoders. The key contribution is the Clinical Report Quality Score (CRQS), which measures factual correctness across four dimensions: clinical fact coverage, key information recall, hallucination rate, and clinical discordance. Experiments show traditional metrics like BLEU and ROUGE are weakly correlated with clinical accuracy, while CRQS reveals meaningful differences.

This study explores adapting an LLM classification pipeline, originally developed on US police data, to estimate the prevalence of four vulnerability indicators (mental ill health, substance misuse, alcohol dependence, homelessness) in UK police incident narratives. Analyzing nearly 3,000 de-identified logs, the research finds that LLMs can provide meaningful prevalence estimates at scale, but naive deployment is unreliable, requiring substantial human input and statistical correction. The study underscores that LLM outputs cannot be treated as valid measurements without careful methodological support.

This paper studies whether lightweight depthwise convolutions can provide local inductive bias to LLMs without materially increasing model size. Macro-level ablation on Qwen3 Transformer blocks finds optimal placement of convolution on projected queries, keys, and values before attention. Micro-level study favors a residual depthwise convolution with kernel size k=3 without extra normalization or activation. Across Qwen3 models and data budgets, this design improves average accuracy on seven downstream benchmarks while adding less than 0.01% parameters. A case study suggests convolution makes repeated token IDs more sensitive to immediate context.
