Inheritance as an Admission Test for LLM Prompt Merge Operators

Zan-Kai Chong, Hiroyuki Ohsaki, Bryan Ng

Large language model (LLM) agents are often improved by iterating until a fixed verifier is done. Once that verifier saturates, the loop has nothing left to climb. We instead score…

Compiling Deterministic Structure into SLM Harnesses

Zan Kai Chong, Hiroyuki Ohsaki, Bryan Ng

Enterprise SLM deployment faces epistemic asymmetry: small models cannot self-correct reasoning errors, while frontier LLMs incur prohibitive costs and data sovereignty risks at sc…

The Silent Scholar Problem: A Probabilistic Framework for Breaking Epistemic Asymmetry in LLM Agents

Zan-Kai Chong, Hiroyuki Ohsaki, Bryan Ng

Autonomous agents powered by LLMs and Retrieval-Augmented Generation (RAG) are proficient consumers of digital content but remain unidirectional, a limitation we term epistemic asy…

Tractable Asymmetric Verification for Large Language Models via Deterministic Replicability

Zan-Kai Chong, Hiroyuki Ohsaki, Bryan Ng

The landscape of Large Language Models (LLMs) shifts rapidly towards dynamic, multi-agent systems. This introduces a fundamental challenge in establishing computational trust, spec…

Improving Uncertainty Sampling with Bell Curve Weight Function

Zan-Kai Chong, Hiroyuki Ohsaki, Bok-Min Goi

Typically, a supervised learning model is trained using passive learning by randomly selecting unlabelled instances to annotate. This approach is effective for learning a model, bu…

Improve Cost Efficiency of Active Learning over Noisy Dataset

Zan-Kai Chong, Hiroyuki Ohsaki, Bryan Ng

Active learning is a learning strategy whereby the machine learning algorithm actively identifies and labels data points to optimize its learning. This strategy is particularly eff…
