Neural-field design of broadband Rayleigh-wave carpet cloaks under microstructure realisability constraints
David Aznaurov, Davit Piliposyan, Danila Rukhovich, Sébastien Guenneau
A neural-field and differentiable-FEM framework for designing broadband Rayleigh-wave carpet cloaks within realizable Cauchy materials and mapping the optimized fields to explicit manufacturable microstructures.

Nikita Drozdov, Andrey Lemeshko, Nikita Gavrilov, Anton Konushin, Danila Rukhovich, Maksim Kolodiazhnyi
A universal pipeline for localizing objects in 3D scenes from multi-view images using zero-shot methods, without geometric supervision or object priors.

Andrey Lemeshko, Bulat Gabdullin, Nikita Drozdov, Anton Konushin, Danila Rukhovich, Maksim Kolodiazhnyi
The first training-free 3D object detection framework. It constructs 3D bounding boxes through graph clustering of 2D instance masks and assigns open-vocabulary semantic labels.

New Paper with Imperial College London on Broadband Rayleigh-Wave Cloaking
We have published a preprint on arXiv with Imperial College London collaborator Sébastien Guenneau. The paper presents a neural-field and differentiable-FEM framework for designing broadband Rayleigh-wave carpet cloaks using physically realizable Cauchy materials. It then maps the optimized fields to explicit manufacturable microstructures through conditional diffusion and inverse design. In finite element validation, the homogenized microstructure model recovers approximately 97% of the defect-free reference surface-displacement magnitude, while the fully resolved geometry recovers approximately 76%.
Zero-Shot 3D Reconstruction with LiteReality-Agent
We tested LiteReality-Agent end-to-end on a scan of our laboratory to explore how code-driven agents can move 3D reconstruction beyond visual appearance toward structured, interactive scenes. A deterministic base pass first reconstructs the empty room, then an agent edits a single Python scene file containing geometry, materials, and articulation. It compares the generated scene with the physical scan, measures discrepancies, and iteratively corrects the code. This is an exploratory step toward useful scene models for design, robotics, and engineering; some objects still remain meshes rather than full CAD models.
New Collaboration with YSU
We are partnering with Yerevan State University's Physical-Technical Laboratory and Department of Radiophysics and Telecommunications to build a digital engineering platform for virtual system modeling and diagnostics. The platform will create digital twins of real experimental systems that scientists can query in plain language for fast, accurate answers, powered by machine-learning models trained on thousands of physics simulations. The project is funded by the Higher Education and Science Committee of RA MESCS, with co-financing from the Enterprise Incubator Foundation.

Our team joined METAMAT2026 in Ajaccio, Corsica, France. David Aznaurov delivered an invited lecture on ongoing work with Imperial College London in machine-learning methods for mechanical structure generation and elastic wave control, alongside five days of exchange on acoustic, mechanical, and thermal metamaterials.
M3L Secures HTI AI Virtual Institute Grant for High-Performance GPU Computing
M3L has received access to NVIDIA H100 GPUs through the AI Virtual Institute, a program of Armenia's Ministry of High-Tech Industry. This support expands our capacity to design elastic metamaterials and wave-cloaking structures. The research combines differentiable FEM, neural-field optimisation, and generative design to create manufacturable microstructures for broadband Rayleigh-wave cloaking and chiral metamaterials.

Zoo3D: Zero-Shot 3D Object Detection at Scene Level
M3L researchers co-authored Zoo3D, accepted at CVPR 2026, a CORE 2023 A*-ranked conference. The work introduces the first training-free, open-vocabulary 3D object detector: it clusters 2D instance masks across views into class-agnostic 3D boxes, then labels them through best-view selection and view-consensus visual-language matching. Zoo3D supports point clouds as well as posed or unposed RGB images, while its zero-shot and self-supervised variants deliver leading results on ScanNet200 and ARKitScenes.
TUN3D: Towards Real-World Scene Understanding from Unposed Images
M3L researchers co-authored TUN3D, accepted at ICRA 2026, a CORE 2023 A*-ranked conference. It is the first system to jointly estimate room layouts and detect 3D objects in real scans from multi-view images without ground-truth camera poses or depth supervision. A lightweight sparse-convolutional backbone feeds dedicated detection and parametric wall-layout heads, enabling one model to work with point clouds, posed images, or fully unposed RGB captures and substantially advancing holistic indoor-scene understanding.
cadrille: Multi-modal CAD Reconstruction with Reinforcement Learning
M3L researchers co-authored cadrille, accepted as an Oral at ICLR 2026, a CORE 2023 A*-ranked conference. The model turns point clouds, multi-view images, or text descriptions into editable Python-based CAD programs within a single vision-language architecture. It combines supervised fine-tuning on large-scale procedurally generated designs with online reinforcement learning driven by programmatic feedback, improving geometric accuracy and code validity and achieving leading results across DeepCAD, Fusion360, CC3D, and Omni-CAD benchmarks. Its earlier arXiv title included ‘Online Reinforcement Learning.’
Enhancing Event-Sequence Embeddings for RAG Systems
M3L is developing a foundational event-embedding model that jointly captures event meaning, temporal progression, and outcome/value signals. The work targets time-sensitive retrieval and agent memory across domains, supporting anomaly and churn detection, next-action and value prediction, causal and counterfactual analysis, and grounded conversational investigation through a Semantic Vector MCP. This work was conducted within the scope of the Faculty Research Funding Program 2025 of the Enterprise Incubator Foundation (EIF).
