Anamnesis: An Open-Source Platform for Large-Scale Backstory-Conditioned Survey Simulation
Song-Ze Yu, Joseph Suh, Serina Chang +1
We present Anamnesis, an interactive system for demographically controllable survey simulation using large language models. Open-source, and designed for non-technical users/resear…
InstructFX2FX: A Multi-Turn Text-to-Effect System for Sequential Audio Effect Refinement
Song-Ze Yu, Milan Liessens Dujardin, Yuxuan Cai +4
We present InstructFX2FX, a system for sequential audio effect refinement through multi-turn natural-language instructions. Existing text-to-effect systems are largely single-shot,…
PitchBench: Measuring Pitch Hearing in Audio-Language Models
Milan Liessens Dujardin, Song-Ze Yu, Craver Corbyn Thomas-Smith +2
Audio-language models (ALMs) are increasingly used in real-world applications that require understanding music, from music tutoring and transcription to captioning, recommendation…
EP-GRPO: Entropy-Progress Aligned Group Relative Policy Optimization with Implicit Process Guidance
Song Yu, Li Li, Wenwen Zhao +1
Reinforcement learning with verifiable rewards (RLVR), particularly Group Relative Policy Optimization (GRPO), has advanced LLM reasoning. However, GRPO suffers from three credit a…
ERPO: Token-Level Entropy-Regulated Policy Optimization for Large Reasoning Models
Song Yu, Li Li, Wenwen Zhao +1
Reinforcement learning from verifiable rewards has significantly advanced the reasoning capabilities of large language models. However, Group Relative Policy Optimization (GRPO) ty…
Tree of Agents: Improving Long-Context Capabilities of Large Language Models through Multi-Perspective Reasoning
Song Yu, Xiaofei Xu, Ke Deng +2
Large language models (LLMs) face persistent challenges when handling long-context tasks, most notably the lost in the middle issue, where information located in the middle of a lo…
