Neural Fine-Tuning Search for Few-Shot Learning

ICLR 2024oral

In few-shot recognition, a classifier that has been trained on one set of classes is required to rapidly adapt and generalize to a disjoint, novel set of classes. To that end, recent studies have shown the efficacy of fine-tuning with carefully-crafted adaptation architectures. However this raises t…

The SIFo Benchmark: Investigating the Sequential Instruction Following Ability of Large Language Models

EMNLP 2024finding

Following multiple instructions is a crucial ability for large language models (LLMs). Evaluating this ability comes with significant challenges: (i) limited coherence between multiple instructions, (ii) positional bias where the order of instructions affects model performance, and (iii) a lack of o…

Weight-covariance alignment for adversarially robust neural networks

ICML 2021spotlight

Stochastic Neural Networks (SNNs) that inject noise into their hidden layers have recently been shown to achieve strong robustness against adversarial attacks. However, existing SNNs are usually heuristically motivated, and often rely on adversarial training, which is computationally costly. We prop…
