Bitrate-Constrained DRO: Beyond Worst Case Robustness To Unknown Group Shifts

1 code implementation • 6 Feb 2023 • Amrith Setlur, Don Dennis, Benjamin Eysenbach, aditi raghunathan, Chelsea Finn, Virginia Smith, Sergey Levine

Some robust training algorithms (e. g., Group DRO) specialize to group shifts and require group information on all training points.

Shallow RNN: Accurate Time-series Classification on Resource Constrained Devices

2 code implementations • NeurIPS 2019 • Don Dennis, Durmus Alp Emre Acar, Vikram Mandikal, Vinu Sankar Sadasivan, Venkatesh Saligrama, Harsha Vardhan Simhadri, Prateek Jain

The second layer consumes the output of the first layer using a second RNN thus capturing long dependencies.

Multiple Instance Learning for Efficient Sequential Data Classification on Resource-constrained Devices

1 code implementation • NeurIPS 2018 • Don Dennis, Chirag Pabbaraju, Harsha Vardhan Simhadri, Prateek Jain

We propose a method, EMI-RNN, that exploits these observations by using a multiple instance learning formulation along with an early prediction technique to learn a model that achieves better accuracy compared to baseline models, while simultaneously reducing computation by a large fraction.
