Deciphering 'What' and 'Where' Visual Pathways from Spectral Clustering of Layer-Distributed Neural Representations

no code implementations11 Dec 2023 Xiao Zhang, David Yunis, Michael Maire

We present an approach for analyzing grouping information contained within a neural network's activations, permitting extraction of spatial layout and semantic segmentation from the behavior of large pre-trained vision models.

Subwords as Skills: Tokenization for Sparse-Reward Reinforcement Learning

no code implementations8 Sep 2023 David Yunis, Justin Jung, Falcon Dai, Matthew Walter

Exploration in sparse-reward reinforcement learning is difficult due to the requirement of long, coordinated sequences of actions in order to achieve any reward.

Jointly Learning to Construct and Control Agents using Deep Reinforcement Learning

3 code implementations ICLR 2018 Charles Schaff, David Yunis, Ayan Chakrabarti, Matthew R. Walter

The physical design of a robot and the policy that controls its motion are inherently coupled, and should be determined according to the task and environment.

Jointly Optimizing Placement and Inference for Beacon-based Localization

1 code implementation24 Mar 2017 Charles Schaff, David Yunis, Ayan Chakrabarti, Matthew R. Walter

The accuracy of such a beacon-based localization system depends both on how beacons are distributed in the environment, and how the robot's location is inferred based on noisy and potentially ambiguous measurements.
