Double-Delta Multi-Fidelity Aerodynamics Dataset
Dataset Summary
This dataset provides an open-source multi-fidelity aerodynamic benchmark for a parametric family of double-delta (cranked-delta) wings, designed to support research in data-driven surrogate modeling, multi-fidelity learning, parametric sensitivity studies and Uncertainty Quantification (UQ) and Physics AI models.
The dataset contains paired low-fidelity Vortex Lattice Method (VLM) and high-fidelity… See the full description on the dataset page: https://huggingface.co/datasets/yirens/double-delta-aero.AIRBOT_MMK2_double-sided_tape_placement

IOAI 2026 — Double Agent Dilemma
Official contest data for Double Agent Dilemma, task 4 (Day 2) of the IOAI 2026 Individual Contest, held in Astana, Kazakhstan.
Two pretrained image classifiers — a ResNet18 (CNN) and a ViT-Tiny (Transformer) — both reach 100% accuracy on the provided images. The task exploits where the two architectures disagree.
The task statement, translations, baseline and grader live in the IOAI-2026 GitHub repository.

Bangla OCR Double Benchmark
Two equally weighted, deterministic full-page Bangla handwriting robustness splits:
bongabdo: 6,669 readability-preserving renderings balanced over all 111 Bongabdo pages.
bn_htrd: 6,669 renderings balanced over all 75 actual files in the writer-separated
BN-HTRd test split.
These are explicitly compositional/augmentation robustness rows, not 13,338 independent
writers or source documents. Every row exposes its source page ID, source SHA-256… See the full description on the dataset page: https://huggingface.co/datasets/Reza2kn/bangla-ocr-double-benchmark.sim_double_insert_round1_0521_v2Double-Bench
Double-Bench: A Multilingual & Multimodal Evaluation System for Document RAG
We introduce Double-Bench, a new large-scale, multilingual, and multimodal evaluation system for assessing Retrieval-Augmented Generation (RAG) systems using Multimodal Large Language Models (MLLMs).
The dataset and benchmark were introduced in the paper Are We on the Right Way for Assessing Document Retrieval-Augmented Generation?.
