Studying Large Language Model Behaviors Under Realistic Knowledge Conflicts

1 code implementation24 Apr 2024 Evgenii Kortukov, Alexander Rubinstein, Elisa Nguyen, Seong Joon Oh

In cases where the models still fail to update their answers, we find a parametric bias: the incorrect parametric answer appearing in context makes the knowledge update likelier to fail.

Do Deep Neural Network Solutions Form a Star Domain?

1 code implementation12 Mar 2024 Ankit Sonthalia, Alexander Rubinstein, Ehsan Abbasnejad, Seong Joon Oh

This means that two independent solutions can be connected by a linear path with low loss, given one of them is appropriately permuted.

Mitigating Biases with Diverse Ensembles and Diffusion Models

no code implementations23 Nov 2023 Luca Scimeca, Alexander Rubinstein, Damien Teney, Seong Joon Oh, Armand Mihai Nicolicioiu, Yoshua Bengio

Spurious correlations in the data, where multiple cues are predictive of the target labels, often lead to a phenomenon known as shortcut learning, where a model relies on erroneous, easy-to-learn cues while ignoring reliable ones.

Leveraging Diffusion Disentangled Representations to Mitigate Shortcuts in Underspecified Visual Tasks

no code implementations3 Oct 2023 Luca Scimeca, Alexander Rubinstein, Armand Mihai Nicolicioiu, Damien Teney, Yoshua Bengio

Spurious correlations in the data, where multiple cues are predictive of the target labels, often lead to shortcut learning phenomena, where a model may rely on erroneous, easy-to-learn, cues while ignoring reliable ones.

Robust positioning of drones for land use monitoring in strong terrain relief using vision-based navigation

no code implementations20 Feb 2018 Oleg Kupervasser, Vitalii Sarychev, Alexander Rubinstein, Roman Yavich

For land use monitoring, the main problems are robust positioning in urban canyons and strong terrain reliefs with the use of GPS system only.
