报告题目：Weakly supervised learning and its applications in remote sensing and digital health

报告摘要：Sensors are regarded as the “electronic sensory organ in information era”, which has changed the live style of humans. Remote Sensing and Digital Health are two typical applications of them, and these sensor systems are yielding massive data each day. How to effectively analyze the data is the key problem for the applications. In recent years, artificial intelligence has become the most promising research topic for data analysis in these two fields. However, there are still some challenges confronting the tasks: i) Label scarcity. ii) Heavy noise. iii) Data variability and heterogeneity. Here, I will present several works from me which address these issues. Different machine learning paradigms, including semi-supervised learning-based, active learning-based and Markov random field-based approaches are designed and applied. The findings from these works point out that making full use of the unlabeled data and the prior knowledge are effective ways to improve the prediction performance and reduce the annotation cost.
