A Framework for Efficient Development and Debugging of Role-Playing Agents with Large Language Models

We propose a framework that leverages large language models (LLMs) to semi-automate the development and debugging of role-playing agents, reducing the need for extensive manual effort. Role-playing agents powered by LLMs offer scalable solutions that enhance communication and interaction in various applications, such…

User-Guided Correction of Reconstruction Errors in Structure-from-Motion

We propose a user-guided method to correct reconstruction errors in Structure-from-Motion (SfM) processes. SfM takes a set of camera images as input and then estimates the cameras' poses and three-dimensional point clouds based on keypoint matching. However, scenes with repetitive or similar structures often result in…

Interactive Hyperparameter Optimization with Paintable Timelines

We propose a method to integrate more interactivity into automatic hyperparameter optimization systems to leverage the user's prior knowledge on parameter distribution. In our method, the user continuously observes automatic optimization's progress and dynamically specifies where to search in the parameter space. We p…
