Work History
AI Algorithm Engineer
Shenzhen Lingxi Smart Technology Co., Ltd.
04.2023 - 05.2024
- Construct a brand-new multi-agent reinforcement learning algorithm(MAT:Multi-Agent-Transformer), integrate it into the game environment developed by our company, carry out detailed design and training. Successfully train multi-agent combatants for both the red and blue sides.
- Write a complete reinforcement learning framework that includes the following features: 1. Includes algorithms such as MAPPO, MADDGP, HAPPO, HATRPO, MAT, QMIX, PPO, A3C, DDPG, TD3, and Rainbow, which can be freely switched; 2. These algorithms have task decoupling capabilities during training, that is, training and data collection tasks are parallel; 3. It is possible to freely switch between red and blue team algorithms, or to undergo self-evolutionary training.
- Build a neural network model for a power grid generation project (such as an improved ResNet, ResNext, or transformer model), using weather forecast data to predict the next day's wind and solar power generation.
AI Algorithm Engineer
Shenzhen Hansen Software Co., Ltd.
03.2022 - 04.2023
- Responsible for the research and optimization of image processing algorithms for large industrial printers, to achieve better printing results.
- Use neural network algorithm models to optimize printer data processing schemes. For example, by training a diffusion model(Latent Diffusion models) to perform tasks similar to image translation, change the distribution pattern of the image points, thereby producing better printing results.
Quant Researcher
Shenzhen Tianma Asset Management Co., Ltd.
07.2019 - 03.2022
- Researching trading strategies for stock portfolios using offline reinforcement learning methods. This involves selecting 15 stocks from a large pool of 100 stocks to hold, with portfolio rebalancing occurring once a week.
- Using machine learning models to research futures trend strategies. Train neural network models, conduct strategy backtesting, and study the strategies. Ultimately, develop a trend strategy model that can achieve an annualized return of 21.6%, a maximum drawdown of 10.2%, and a Sharpe ratio of 2.02.
- Constructed an automated research framework for studying quantitative investment strategies using machine learning: includes automated code for a series of operations such as data cleaning, factor generation, model selection, model training, strategy optimization, strategy backtesting, and strategy validation.
