Can We Predict Performance of Large Models across Vision-Language Tasks?

ICML 2025poster

Evaluating large vision-language models (LVLMs) is very expensive, due to high computational cost and the wide variety of tasks. The good news is that if we already have some observed performance scores, we may be able to infer unknown ones. In this study, we propose a new framework for predicting u…

The First to Know: How Token Distributions Reveal Hidden Knowledge in Large Vision-Language Models?

ECCV 2024poster

"Large vision-language models (LVLMs), designed to interpret and respond to human instructions, occasionally generate hallucinated or harmful content due to inappropriate instructions. This study uses linear probing to shed light on the hidden knowledge at the output layers of LVLMs. We demonstrate…

Towards Optimal Feature-Shaping Methods for Out-of-Distribution Detection

ICLR 2024poster

Feature shaping refers to a family of methods that exhibit state-of-the-art performance for out-of-distribution (OOD) detection. These approaches manipulate the feature representation, typically from the penultimate layer of a pre-trained deep learning model, so as to better differentiate between in…

Improved Gradient-Based Adversarial Attacks for Quantized Networks

AAAI 2022technical

Neural network quantization has become increasingly popular due to efficient memory consumption and faster computation resulting from bitwise operations on the quantized networks. Even though they exhibit excellent generalization capabilities, their robustness properties are not well-understood. In…

Calibration of Neural Networks using Splines

ICLR 2021poster

Calibrating neural networks is of utmost importance when employing them in safety-critical applications where the downstream decision making depends on the predicted probabilities. Measuring calibration error amounts to comparing two empirical distributions. In this work, we introduce a binning-free…

Mirror Descent View for Neural Network Quantization

AISTATS 2021poster

Quantizing large Neural Networks (NN) while maintaining the performance is highly desirable for resource-limited devices due to reduced memory and time complexity. It is usually formulated as a constrained optimization problem and optimized via a modified version of gradient descent. In this work, b…

Near-contact grasping strategies from awkward poses: When simply closing your fingers is not enough

IROS 2019poster

Grasping a simple object from the side is easy — unless the object is almost as big as the hand or space constraints require positioning the robot hand awkwardly with respect to the object. We show that humans — when faced with this challenge — adopt coordinated finger movements which enable them to…
