• Reinforcement Learning via Value Gradient Flow — Haoran Xu, Kaiwen Hu, Somayeh Sojoudi. We study behavior-regularized reinforcement learning (RL), where regularization toward a reference distribution (the dataset in offline RL or the base model in LLM RL finetuning) is essential to preve...
• Beyond Prompts: Unconditional 3D Inversion for Out-of-Distribution Shapes — Victoria Yue Chen, Emery Pierson, Léopold Maillard. Text-driven inversion of generative models is a core paradigm for manipulating 2D or 3D content, unlocking numerous applications such as text-based editing, style transfer, or inverse problems.
• Three-Phase Transformer — Mohammad R. Abu Ayyash. We present Three-Phase Transformer (3PT), a residual-stream structural prior for decoder-only Transformers on a standard SwiGLU + RMSNorm + RoPE + GQA backbone.
• An Optimal Transport-driven Approach for Cultivating Latent Space in Online Incr — Quyen Tran, Hai Nguyen, Hoang Phan. In online incremental learning, data continuously arrives with substantial distributional shifts, creating a significant challenge because previous samples have limited replay value when learning a ne...
• Boosting Visual Instruction Tuning with Self-Supervised Guidance — Sophia Sirko-Galouchenko, Monika Wysoczanska, Andrei Bursuc. Multimodal large language models (MLLMs) perform well on many vision-language tasks but often struggle with vision-centric problems that require fine-grained visual reasoning.
