Patching open-vocabulary models by interpolating weights

1 code implementation10 Aug 2022 Gabriel Ilharco, Mitchell Wortsman, Samir Yitzhak Gadre, Shuran Song, Hannaneh Hajishirzi, Simon Kornblith, Ali Farhadi, Ludwig Schmidt

We study model patching, where the goal is to improve accuracy on specific tasks without degrading accuracy on tasks where performance is already adequate.

Structure from Action: Learning Interactions for Articulated Object 3D Structure Discovery

no code implementations19 Jul 2022 Neil Nie, Samir Yitzhak Gadre, Kiana Ehsani, Shuran Song

We introduce Structure from Action (SfA), a framework to discover 3D part geometry and joint parameters of unseen articulated objects via a sequence of inferred interactions.

Continuous Scene Representations for Embodied AI

no code implementations CVPR 2022 Samir Yitzhak Gadre, Kiana Ehsani, Shuran Song, Roozbeh Mottaghi

Our method captures feature relationships between objects, composes them into a graph structure on-the-fly, and situates an embodied agent within the representation.

CoWs on Pasture: Baselines and Benchmarks for Language-Driven Zero-Shot Object Navigation

1 code implementation CVPR 2023 Samir Yitzhak Gadre, Mitchell Wortsman, Gabriel Ilharco, Ludwig Schmidt, Shuran Song

To better evaluate L-ZSON, we introduce the Pasture benchmark, which considers finding uncommon objects, objects described by spatial and appearance attributes, and hidden objects described relative to visible objects.

Model soups: averaging weights of multiple fine-tuned models improves accuracy without increasing inference time

6 code implementations10 Mar 2022 Mitchell Wortsman, Gabriel Ilharco, Samir Yitzhak Gadre, Rebecca Roelofs, Raphael Gontijo-Lopes, Ari S. Morcos, Hongseok Namkoong, Ali Farhadi, Yair Carmon, Simon Kornblith, Ludwig Schmidt

The conventional recipe for maximizing model accuracy is to (1) train multiple models with various hyperparameters and (2) pick the individual model which performs best on a held-out validation set, discarding the remainder.
