🚗 IEDD: An Interactive Enhanced Driving Dataset for Autonomous Driving [Scientific Data 2026]
🌲 As AutonomousDriving evolves toward VLA, sparse interactive scenarios and weak multimodal alignment remain critical bottlenecks. Existing datasets heavily bias toward straight-line cruising while severely under-representing long-tail interactive events (cut-in, merging, pedestrian crossing, head-on avoidance). IEDD introduces a physics-aware, interaction-dense dataset (plus IEDD-VQA multimodal extension) mined from 7.31M ego-centric scenes across Waymo, nuPlan, Lyft, INTERACTION, SIND — with 91% multi-agent interactions, dual Intensity–Efficiency metrics, pixel-level BEV-video alignment, rule-based hallucination-free language, and hierarchical L1–L4 VLM benchmarking. 🌍 It lays a scalable, causality-grounded foundation to evolve general-purpose VLMs into truly capable autonomous driving experts. 🤗 HuggingFace, LinkedIn, X. -
📊 QuantEval: A Benchmark for Financial Quantitative Tasks in Large Language Models [ACL 2026]
🧪 Evaluation and domain knowledge are the core bottlenecks of Quant + AI. Without expert-level, strong verifiers for evaluation, models cannot reliably assess performance in multi-step strategy generation, risk control, or real-world trading effectiveness. QuantEval is proposed in this context, providing a reproducible benchmark framework that goes beyond static question answering and shifts toward evaluation grounded in realistic trading details. It represents an initial exploration of evaluating financial “World Models.” 🌍
- Finalist & Track Winner, 🏆 Y Combinator Hackathon 2025
Inspired by Isaac Asimov’s Foundation, PsychoHistory is a probabilistic forecasting system that maps the branching futures of human events—combining history, data, and AI to model the flow of possibility. 🧠 Our approach blended SFT+RL, training the model not just what to predict but how to reason across alternative futures—like a psychohistorian trained on uncertainty itself. - Meritorious Winner, Mathematical Contest in Modeling.
- Finalist, Asia Supercomputer Challenge.
- Top 10 Algo Trader, Rotman International Trading Competition.
- Outstanding Thesis (1%).
- Invited Reviewer, ACM Conf (AI Agentic Systems), 2026. Nominated by committee for research contributions.
