Hi, I'm Gao Fengkai.

I build practical AI tools and research systems that can be inspected, tested, and reproduced.

My current work focuses on local-first applications and agent workflows. Earlier research includes agent memory, scientific figure integrity, and diffusion-model control.

Selected engineering

Vibe-Trading Windows

A Windows desktop implementation for Vibe-Trading that hosts the React interface and FastAPI service in an Electron lifecycle, with bounded local networking and process cleanup.

IELTS Study Desk

A local-first IELTS Academic study application with four-skill practice, mock exams, persistent study threads, progress tracking, and reviewed PDF and OCR content import.

Research

Training-Free Concept Disentanglement in Text-to-Image Generation via Detection-Guided Attention Control

Training-free spatial-gated cross-attention control using open-vocabulary detection priors to reduce attribute leakage during diffusion inference.

ShiftMem

A conditional memory lifecycle for inventory agents under regime shifts, evaluated in 160 completed runs. The prespecified comparison did not support an advantage over the lexical baseline.

DSMAF Light

A 1,000-sample benchmark for semantic manipulation in structured academic figures, with a structured extraction and consistency-checking baseline.

Revisiting FreeU

A reproduction and frequency-domain analysis of FreeU, followed by a time-aware feature modulation schedule. With Zhu Jiatong.

Experience

Data Governance and AI Applications Intern

Chongqing Municipal Commission of Commerce, Information and Data Center

Worked on commerce data inventories, metric definitions, source mapping, retrieval evaluation, and failure analysis for downstream analytics and AI applications.
