Summary
I am a person who loves to challenge myself and push myself to limits. I have developed a strong interest in machine learning during my first internship at Dentsu Aegis Network. I believe artificial intelligence will shape our future more powerfully than any other innovation this century. As Jack Ma once said: the most powerful energy driving the future manufacturing industry will be data and I will strive hard to contribute in turning data into valuable insights!
