Context-Parametric Inversion: Why Instruction Finetuning May Not Actually Improve Context Reliance

ICLR 2025oral

Large Language Model's are instruction-finetuned to enhance their ability to follow user instructions and better comprehend input context. Still, they often struggle to follow the input context, especially when it contradicts model's parametric knowledge. This manifests as various failures, such as…

Predicting the Performance of Foundation Models via Agreement-on-the-Line

NeurIPS 2024poster

Estimating the out-of-distribution performance in regimes where labels are scarce is critical to safely deploy foundation models. Recently, it was shown that ensembles of neural networks observe the phenomena "agreement-on-the-line", which can be leveraged to reliably predict OOD performance without…

Test-Time Adaptation Induces Stronger Accuracy and Agreement-on-the-Line

NeurIPS 2024poster

Recently, Miller et al. (2021) and Baek et al. (2022) empirically demonstrated strong linear correlations between in-distribution (ID) versus out-of-distribution (OOD) accuracy and agreement. These trends, coined accuracy-on-the-line (ACL) and agreement-on-the-line (AGL), enable OOD model selection…

Agreement-on-the-line: Predicting the Performance of Neural Networks under Distribution Shift

NeurIPS 2022accept

Recently, Miller et al. showed that a model's in-distribution (ID) accuracy has a strong linear correlation with its out-of-distribution (OOD) accuracy, on several OOD benchmarks, a phenomenon they dubbed ``accuracy-on-the-line''. While a useful tool for model selection (i.e., the model most likely…

Assessing Generalization of SGD via Disagreement

ICLR 2022spotlight

We empirically show that the test error of deep networks can be estimated by training the same architecture on the same training set but with two different runs of Stochastic Gradient Descent (SGD), and then measuring the disagreement rate between the two networks on unlabeled test data. This builds…

Efficient Maximal Coding Rate Reduction by Variational Forms

CVPR 2022poster

The principle of Maximal Coding Rate Reduction (MCR2) has recently been proposed as a training objective for learning discriminative low-dimensional structures intrinsic to high-dimensional data to allow for more robust training than standard approaches, such as cross-entropy minimization. However,…

Robust Human Following by Deep Bayesian Trajectory Prediction for Home Service Robots

ICRA 2018poster

The capability of following a person is crucial in service-oriented robots for human assistance and cooperation. Though a vast variety of following systems exist, they lack robustness against dynamic changes of the environment and relocating to continue following a lost target. Here we present a rob…
