Title: Identification of rice plant diseases using deep learning

Abstract: Rice is one of the most important crops in the world, and most people consume rice as a staple food, especially in Asian countries. Various rice plant diseases have a negative effect on crop yields. If proper detection is not taken, they can spread and lead to a significant decline in agricultural productions. In severe cases, they may even cause no grain harvest entirely, thus having a devastating impact on food security. This talk will introduce our research on deep learning models for rice plant diseases.  The computational results are reported.

Title: Research on ocean multi-modal data fusion

Abstract: With the widespread use of computing devices and multimedia technologies, multimodal data is becoming more and more common in daily life. For example, in social life, people use different modal data, such as images, texts, videos, to express their moods when posting updates on Weibo, WeChat and other social software. Therefore, how to analyze and process multimodal data and capture the complementary knowledge hidden in multimodal data becomes an urgent problem to be solved. For example, in the ocean data analysis task, in order to process the multi-domain, multi-source, optical-acoustic-electric-magnetic and other multi-modal data from the sky and the coast, the analysis algorithm based on the marine multi-modal data should be designed to perform effective analysis of marine multimodal data. For multimodal analysis in real scenarios, present works first collect multi-modal data with the help of multi-source heterogeneous sensor equipment, which provides the basis for multi-modal data analysis. Then, these heterogeneous data are mapped to a common space through algorithms to capture the common information of multimodal data. Finally, fusion techniques are used to fuse these features to obtain complementary knowledge of multimodal data. However, the whole multimodal analysis process still has the problems of data imbalance, data mismatch and multiple modalities, which requires further research. Aiming at the problem of data imbalance in data acquisition based on multi-source equipment, a multi-modal low-rank tensor data reconstruction algorithm for imbalanced data is designed to complete imbalanced multi-modal data; For the problem of multi-modal data scales non-uniformity, an anchored multi-modal alignment method for multi-scale data is designed to achieve mismatched data alignment; for the feature fusion problem of multi-modal data, deep semantic feature fusion method for multi-modal data is designed to achieve multi-modality data fusion.
