Parity Calibration

1 code implementation29 May 2023 Youngseog Chung, Aaron Rumack, Chirag Gupta

In a sequential regression setting, a decision-maker may be primarily concerned with whether the future observation will increase or decrease compared to the current one, rather than the actual value of the future observation.

Bi-Manual Block Assembly via Sim-to-Real Reinforcement Learning

no code implementations27 Mar 2023 Satoshi Kataoka, Youngseog Chung, Seyed Kamyar Seyed Ghasemipour, Pannag Sanketi, Shixiang Shane Gu, Igor Mordatch

Without manually-designed controller nor human demonstrations, we demonstrate that with careful Sim2Real considerations, our policies trained with RL in simulation enable two xArm6 robots to solve the U-shape assembly task with a success rate of above90% in simulation, and 50% on real hardware without any additional real-world fine-tuning.

Beyond Pinball Loss: Quantile Methods for Calibrated Uncertainty Quantification

2 code implementations NeurIPS 2021 Youngseog Chung, Willie Neiswanger, Ian Char, Jeff Schneider

However, this loss restricts the scope of applicable regression models, limits the ability to target many desirable properties (e. g. calibration, sharpness, centered intervals), and may produce poor conditional quantiles.

Neural Dynamical Systems: Balancing Structure and Flexibility in Physical Prediction

no code implementations23 Jun 2020 Viraj Mehta, Ian Char, Willie Neiswanger, Youngseog Chung, Andrew Oakleigh Nelson, Mark D Boyer, Egemen Kolemen, Jeff Schneider

We introduce Neural Dynamical Systems (NDS), a method of learning dynamical models in various gray-box settings which incorporates prior knowledge in the form of systems of ordinary differential equations.
