Hi! I am a senior undergraduate in Department of Automation, School of Information Science and Technology, Tsinghua University. I will become a PhD student in the Computer Science Department at Stanford University in 2017 fall.
Since April 2016, I've been working with Prof. Stefano Ermon and Prof. David Lobell, and spent a memorable summer in Stanford Artificial Intelligence Laboratory. In Tsinghua, I've been working on Machine Learning since October 2015, supervised by Prof. Jun Zhu. Before stepping into the world of AI, I had been working on modeling and simulation, under the supervision of Prof. Yi Zhang.
My research interests lie within Machine Learning.

Crop Yield Prediction -- Machine Learning over Satellite Images

Jiaxuan You, Xiaocheng Li, Melvin Low, David Lobell, Stefano Ermon

Crop yield prediction is central in ensuring the food security. We introduce a scalable, accurate, and inexpensive method to predict crop yield using publicly available remote sensing data. A novel dimensionality reduction method is proposed based on histogram calculation. By combining Gaussian Process with Convolutional Neural Networks or Long-short Term Memory, the model significantly outperforms traditional models, and we show that the features automatically extracted by deep learning models are much more effective than traditional hand-crafted features.

Misc.

  • I play drones. Some of the highlight videos are in my youtube channel.
  • I've traveled to lots of places. See a map.
  • My life is driven by a simple but powerful idea, "Making the world a better place". Therefore, before turning into AI research, I've done researches in Chemistry, Economics, Social Science, Transportation and Simulation. These varied research experiences have equipped me with competence, creativity and perseverance, in the meantime, have convinced me that AI is the right path to fulfill my dream.
