Scanning Trojaned Models Using Out-of-Distribution Samples
Scanning for trojan (backdoor) in deep neural networks is crucial due to their significant real-world applications. There has been an increasing focus on developing effective general trojan scanning methods across various trojan attacks. Despite advancements, there remains a shortage of methods that perform effectively without preconceived assumptions about the backdoor attack method. Additionally, we have observed that current methods struggle to identify classifiers trojaned using adversarial training. Motivated by these challenges, our study introduces a novel scanning method named TRODO (TROjan scanning by Detection of adversarial shifts in Out-of-distribution samples).
Rethinking the Pruning Criteria for Convolutional Neural Network
Channel pruning is a popular technique for compressing convolutional neural networks (CNNs), where various pruning criteria have been proposed to remove the redundant filters. From our comprehensive experiments, we found two blind spots of pruning criteria: (1) Similarity: There are some strong similarities among several primary pruning criteria that are widely cited and compared. According to these criteria, the ranks of filters' Importance Score are almost identical, resulting in similar pruned structures.
Do Blind Spots Matter for Word-Referent Mapping? A Computational Study with Infant Egocentric Video
Shi, Zekai, Cai, Zhixi, Stefanov, Kalin
Typically, children start to learn their first words between 6 and 9 months, linking spoken utterances to their visual referents. Without prior knowledge, a word encountered for the first time can be interpreted in countless ways; it might refer to any of the objects in the environment, their components, or attributes. Using longitudinal, egocentric, and ecologically valid data from the experience of one child, in this work, we propose a self-supervised and biologically plausible strategy to learn strong visual representations. Our masked autoencoder-based visual backbone incorporates knowledge about the blind spot in human eyes to define a novel masking strategy. This mask and reconstruct approach attempts to mimic the way the human brain fills the gaps in the eyes' field of view. This represents a significant shift from standard random masking strategies, which are difficult to justify from a biological perspective. The pre-trained encoder is utilized in a contrastive learning-based video-text model capable of acquiring word-referent mappings. Extensive evaluation suggests that the proposed biologically plausible masking strategy is at least as effective as random masking for learning word-referent mappings from cross-situational and temporally extended episodes.

We would like to thank the reviewers for their comments and remarks. Reviewers #1 and #4 inquired about the quality of our method with smaller training sets. Training images Method all 10 000 1000 500 300 200 100 (10 runs) Baseline, N2C 31.60 31.59 Reviewer #1 remarked that our experiments are performed on synthetic data only. As the non-learned CBM3D method is also designed for natural images, we feel that our comparisons are fair.
Why do horses have eyes on the side of their head?
Why do horses have eyes on the side of their head? 'You often have to teach horses something on both sides of their body for them to process the information fully.' In the animal kingdom, horses are prey. Breakthroughs, discoveries, and DIY tips sent every weekday. Have you ever noticed that horses have eyes on the sides of the head rather than the front, like we do as humans? The location of horses' eyes offer a biological advantage that helps keep them safe as prey animals.

Towards Continual Expansion of Data Coverage: Automatic Text-guided Edge-case Synthesis
The performance of deep neural networks is strongly influenced by the quality of their training data. However, mitigating dataset bias by manually curating challenging edge cases remains a major bottleneck. To address this, we propose an automated pipeline for text-guided edge-case synthesis. Our approach employs a Large Language Model, fine-tuned via preference learning, to rephrase image captions into diverse textual prompts that steer a Text-to-Image model toward generating difficult visual scenarios. Evaluated on the FishEye8K object detection benchmark, our method achieves superior robustness, surpassing both naive augmentation and manually engineered prompts. This work establishes a scalable framework that shifts data curation from manual effort to automated, targeted synthesis, offering a promising direction for developing more reliable and continuously improving AI systems.

Synthetic Founders: AI-Generated Social Simulations for Startup Validation Research in Computational Social Science
We present a comparative docking experiment that aligns human-subject interview data with large language model (LLM)-driven synthetic personas to evaluate fidelity, divergence, and blind spots in AI-enabled simulation. Fifteen early-stage startup founders were interviewed about their hopes and concerns regarding AI-powered validation, and the same protocol was replicated with AI-generated founder and investor personas. A structured thematic synthesis revealed four categories of outcomes: (1) Convergent themes - commitment-based demand signals, black-box trust barriers, and efficiency gains were consistently emphasized across both datasets; (2) Partial overlaps - founders worried about outliers being averaged away and the stress of real customer validation, while synthetic personas highlighted irrational blind spots and framed AI as a psychological buffer; (3) Human-only themes - relational and advocacy value from early customer engagement and skepticism toward moonshot markets; and (4) Synthetic-only themes - amplified false positives and trauma blind spots, where AI may overstate adoption potential by missing negative historical experiences. We interpret this comparative framework as evidence that LLM-driven personas constitute a form of hybrid social simulation: more linguistically expressive and adaptable than traditional rule-based agents, yet bounded by the absence of lived history and relational consequence. Rather than replacing empirical studies, we argue they function as a complementary simulation category - capable of extending hypothesis space, accelerating exploratory validation, and clarifying the boundaries of cognitive realism in computational social science.
Diffusing the Blind Spot: Uterine MRI Synthesis with Diffusion Models
Müller, Johanna P., Knupfer, Anika, Blöss, Pedro, Vittur, Edoardo Berardi, Kainz, Bernhard, Hutter, Jana
Despite significant progress in generative modelling, existing diffusion models often struggle to produce anatomically precise female pelvic images, limiting their application in gynaecological imaging, where data scarcity and patient privacy concerns are critical. To overcome these barriers, we introduce a novel diffusion-based framework for uterine MRI synthesis, integrating both unconditional and conditioned Denoising Diffusion Probabilistic Models (DDPMs) and Latent Diffusion Models (LDMs) in 2D and 3D. Our approach generates anatomically coherent, high fidelity synthetic images that closely mimic real scans and provide valuable resources for training robust diagnostic models. We evaluate generative quality using advanced perceptual and distributional metrics, benchmarking against standard reconstruction methods, and demonstrate substantial gains in diagnostic accuracy on a key classification task. A blinded expert evaluation further validates the clinical realism of our synthetic images. We release our models with privacy safeguards and a comprehensive synthetic uterine MRI dataset to support reproducible research and advance equitable AI in gynaecology.

I'm a cyclist. Will the arrival of robotaxis make my journeys safer?
Having plied their trade in several US and Chinese cities for years, driverless taxis are on their way to London. As a cyclist, a Londoner and a journalist who has spent years covering AI's pratfalls, I am a tad nervous. Yet, given how often I have been struck by inattentive human drivers in London, part of me is cautiously optimistic. At the end of the day it boils down to this: will I be better off surrounded by tired, distracted and angry humans, or unpredictable and imperfect AI? The UK government has decided to allow firms like Uber to run pilots of self-driving "taxi- and bus-like" services in 2026.
