Program-as-Weights: A Programming Paradigm for Fuzzy Functions

Wentao Zhang, Liliana Hotsko, Woojeong Kim +3

Many everyday programming tasks resist clean rule-based implementation, such as alerting on important log lines, repairing malformed JSON, or ranking search results by intent, and…

Auto-Adaptive PINNs with Applications to Phase Transitions

Kevin Buck, Woojeong Kim

We propose an adaptive sampling method for the training of Physics Informed Neural Networks (PINNs) which allows for sampling based on an arbitrary problem-specific heuristic which…

GOPO: Policy Optimization using Ranked Rewards

Kyuseong Choi, Dwaipayan Saha, Woojeong Kim +2

Standard reinforcement learning from human feedback (RLHF) trains a reward model on pairwise preference data and then uses it for policy optimization. However, while reward models…

From Chat Logs to Collective Insights: Aggregative Question Answering

Wentao Zhang, Woojeong Kim, Yuntian Deng

Conversational agents powered by large language models (LLMs) are rapidly becoming integral to our daily interactions, generating unprecedented amounts of conversational data. Such…

OverFill: Two-Stage Models for Efficient Language Model Decoding

Woojeong Kim, Junxiong Wang, Jing Nathan Yan +2

Large language models (LLMs) excel across diverse tasks but face significant deployment challenges due to high inference costs. LLM inference comprises prefill (compute-bound) and…

DICE-BENCH: Evaluating the Tool-Use Capabilities of Large Language Models in Multi-Round, Multi-Party Dialogues

Kyochul Jang, Donghyeon Lee, Kyusik Kim +4

Existing function-calling benchmarks focus on single-turn interactions. However, they overlook the complexity of real-world scenarios. To quantify how existing benchmarks address p…
