Rethinking Agent Design: From Top-Down Workflows to Bottom-Up Skill Evolution

Introduction

This repository contains the official implementation of the paper
“Rethinking Agent Design: From Top-Down Workflows to Bottom-Up Skill Evolution”.
Our bottom-up agents learn skills through autonomous exploration and reasoning—starting from raw pixel inputs and simulated mouse/keyboard actions, evolving competence purely from experience.

Diversity-Driven Synthesis: Enhancing Dataset Distillation through Directed Weight Adjustment

Overview

Dataset distillation aims to compress a large dataset into a much smaller synthetic dataset while preserving its training utility. Our method, Directed Weight Adjustment (DWA), enhances dataset distillation by promoting diversity in the synthetic data through carefully directed adjustments to the optimization process.
