Goal
• Help people get introduced into DL
• Help investors find potential projects
• Utilize wonderful techniques to solve problems
Schedule
• Deep Learning frameworks and research
• Products that already utilize DL
• Chat-robots and Q&A system
Who I am
• Now data scientist in jianshu.com
• work on recommender system
• research on social network analysis and game theory (ICTAI 2012)
• recently get involved in deep learning on NLP and social network analysis
What is the Deep Learning!?
• simply another name for Neural Networks
• incorporate new thinkings
• heavy computation resources consumer
