Regularized Entropy Information Adaptation with Temporal-Awareness Networks for Simultaneous Speech Translation

Joseph Liu, Nameer Hirschkind, Xiao Yu +1

Simultaneous Speech Translation (SimulST) requires balancing high translation quality with low latency. Recent work introduced REINA, a method that trains a Read/Write policy based…

Taxonomy-Adaptive Moderation Model with Robust Guardrails for Large Language Models

Mahesh Kumar Nandwana, Youngwan Lim, Joseph Liu +3

Large Language Models (LLMs) are typically aligned for safety during the post-training phase; however, they may still generate inappropriate outputs that could potentially pose ris…

StyleMotif: Multi-Modal Motion Stylization using Style-Content Cross Fusion

Ziyu Guo, Young Yoon Lee, Joseph Liu +3

We present StyleMotif, a novel Stylized Motion Latent Diffusion model, generating motion conditioned on both content and style from multiple modalities. Unlike existing approaches…
