Bio-Inspired Distributed Neural Locomotion Controller (D-NLC) for Robust Locomotion and Emergent Behaviors

ICRA 2025

Despite having fewer neurons than more complex life forms, insects are still capable of producing astonishing locomotive behaviors, such as traversing diverse environments and making rapid gait adaptations after extreme injury or autotomy. Biologists attribute this to a chain of segmental neuron clu

Discriminative Finetuning of Generative Large Language Models without Reward Models and Human Preference Data

ICML 2025poster

Supervised fine-tuning (SFT) has become a crucial step for aligning pretrained large language models (LLMs) using supervised datasets of input-output pairs. However, despite being supervised, SFT is inherently limited by its generative training objective. To address its limitations, the existing com…

To Cool or not to Cool? Temperature Network Meets Large Foundation Models via DRO

ICML 2024poster

The temperature parameter plays a profound role during training and/or inference with large foundation models (LFMs) such as large language models (LLMs) and CLIP models. Particularly, it adjusts the logits in the softmax function in LLMs, which is crucial for next token generation, and it scales th…

Local-Global Defense against Unsupervised Adversarial Attacks on Graphs

AAAI 2023technical

Unsupervised pre-training algorithms for graph representation learning are vulnerable to adversarial attacks, such as first-order perturbations on graphs, which will have an impact on particular downstream applications. Designing an effective representation learning strategy against white-box attack…
