In recent years, pattern recognition has become a hot research branch thanks to the recent advances of machine learning driven by big data. In light of the fast-paced advancements in pattern recognition taking place all over the world, it is of great interest to keep an eye on the state-of-the-art research and development and to facilitate collaboration in multidisciplinary research areas. With this end in view, it’s a great pleasure for me to invite you to participate in 2019 4th International Workshop on Pattern Recognition during June 28-30, 2019 in Nanjing, China.
IWPR was established in 2016 and was successfully held in Tokyo, Japan (2016), Nanyang Technological University, Singapore (2017), Jinan University, China(2018). In the last three years, IWPR attracted attendees from more than 15 countries. It was praised for the richness of its social networking, was widely recognized for its continuous adaptation to emerging technical trends, and attracting numerous industry and academic players. The IWPR encompasses all technical aspects of specifying, developing and evaluating the theoretical underpinnings and applied mechanisms of the AI-based components of computer tools such as algorithms, architectures and languages.
