Lee-Xieng Yang

I am a cognitive psychologist in National Chengchi University in Taiwan. My major research interest is investigating human cognitive functions, including categorization, function learning, working memory, and forecasting. In order to understand how cognitive functions work, I do not only conduct behavioral experiments, but also develop computational models (i.e., neural network models or Bayesian models) to account for human cognitive functions. I also explore to what extent individuals’ performance in complex economic situation (e.g., earned profits in the games of beauty contest or double acuation) can be explained by their fundamental cognitive functions (e.g., working memory capacity).

Data science is another research interest of mine. Specifically, I am developing methods to analze the data collected on the web pages as well as social media with the techniques such as web scraping, text mining (or text analysis), Chinese word segmentation, SVM, and other related ones. Due to the success of convolutional neural network (CNN), I also start to explore the possibility of linking CNN (or other models in deep learning) to the old cognitive models to improve their ecological validity. To these ends, R and Python are the computer languages I use often. My full CV can be downlowaded here.
