Principal Investigator  
Principal Investigator's Name: Xi Chen
Institution: Sun Yat-sen University Cancer Center
Department: Department of Nasopharyngeal Carcinoma
Country:
Proposed Analysis: We performed lipidomic analysis on plasma of a group of nasopharyngeal carcinoma patients before treatment, but due to the small sample size (n=150), we hope to apply metabolomics data for model pre-training. It remains challenging to build good predictive models especially when the sample size is limited and the number of features is high. By reading the literatures, we laerned a meta-learning approach for survival analysis. Meta-learning is a significantly more effective paradigm to leverage highdimensional data that is relevant but not directly related to the problem of interest. Specifically, meta-learning explicitly constructs a model, from abundant data of relevant tasks, to learn a new task with few samples effectively. Theerefore, we would like to apply here for ADNI data for meta-learning.
