LiveBench: A Challenging, Contamination-Limited LLM Benchmark

ICLR 2025spotlight

Test set contamination, wherein test data from a benchmark ends up in a newer model's training set, is a well-documented obstacle for fair LLM evaluation and can quickly render benchmarks obsolete. To mitigate this, many recent benchmarks crowdsource new prompts and evaluations from human or LLM jud…

Neural-Kalman GNSS/INS Navigation for Precision Agriculture

ICRA 2023poster

Precision agricultural robots require high-resolution navigation solutions. In this paper, we introduce a robust neural-inertial sequence learning approach to track such robots with ultra-intermittent GNSS updates. First, we propose an ultra-lightweight neural-Kalman filter that can track agricultur…

Mango: A Python Library for Parallel Hyperparameter Tuning

ICASSP 2020accepted

Tuning hyperparameters for machine learning algorithms is a tedious task, one that is typically done manually. To enable automated hyperparameter tuning, recent works have started to use techniques based on Bayesian optimization. However, to practically enable automated tuning for large scale machin…

Sim2Real Transfer for Deep Reinforcement Learning with Stochastic State Transition Delays

CoRL 2020

Deep Reinforcement Learning (RL) has demonstrated to be useful for a wide variety of robotics applications. To address sample efficiency and safety during training, it is common to train Deep RL policies in a simulator and then deploy to the real world, a process called Sim2Real transfer. For roboti
