Hi, I’m Davide Liu

Who am I?

Well…There are 3 versions of me:

  • I’m a blogger and I love talking about technical topics in a friendly and conversational way. I want you to enjoy the process of learning as I do.
  • I’m a data scientist and what I do is feed hungry machine learning models with tons of data. I hope they can learn better than I do.
  • I’m an athlete and I can’t spend a single day without running. I enjoy getting my legs to soar on the track, running out of breath on the road, and getting lost on mountain trails.

Short biography

Davide Liu completed his Bachelor’s in Computer Science in Italy at the University of Padova in 2019 and obtained his Master’s in Advanced Computing at Tsinghua University in 2021 conducting research in Reinforcement Learning and Security in AI. His goal is to use AI in a safe and smart way to improve the quality of our life. During his studies, he had the opportunity to attend internships in two AI startups: one in Italy where he improved an existing computer vision algorithm that lead to winning a challenge organized by the US Pentagon, and one in China doing research on novel architectures for recommendation systems which lead to four conference publications. Currently, he is working full-time as AI researcher at SenseTime in Beijing. Outside of his professional life, Davide is an online blogger, athlete, and videogames developer.

Academic experiences

2016-2019 Bachelor’s degree in Computer Science at Padova University in Italy.

  • In 2018 I was among the 30 students selected to take part in a cybersecurity and CTF challenge national training program called Cyberchallenge led locally by the Spritz (Security & Privacy Research) group under the supervision of prof. Mauro Conti.
  • In 2019 I joined the VIMP (Visual Intelligence and Machine Perception) group and conducted my thesis research on object tracking and detection under the supervision of prof. Lamberto Ballan. My work was done while in an internship for the startup Studiomapp supported by its founder Leonardo Dal Zovo.

2019-2021 Master’s degree in Computer Science at Tsinghua University in China.

  • In 2020 I joined the TSAIL (Tsinghua Statistical Artificial Intelligence & Learning) group where conducted my thesis research on the robustness of reinforcement learning algorithms against adversarial policies under the supervision of prof. Jun Zhu.
