信息科学与工程学院生物信息学系列报告预告

1. 报告题目: Pathological Image Classification Based on Deep Learning Methods

报告人:张法 中国科学院计算技术研究所 教授

报告时间:2019年12月21日 8:30-9:30

报告地点:JC1011

报告摘要:

Histopathological diagnosis is considered the gold standard in diagnosing cancer. Although the application of deep learning has greatly improved the performance of Pathological Image Classification, the accuracy of classification has been unable to meet the requirements of clinical practice. In this talk, I will introduce two kind of breast cancer histopathological image classification based on deep learning methods, one is a hybrid convolutional and recurrent deep neural network for breast cancer histopathological image classification, which integrates the advantages of convolutional and recurrent neural networks. The other is a new hybrid deep learning method for breast cancer classification using fusion of multimodal data.

2. 报告题目:Finding Remote Homologous Proteins: Alignment-Based, Alignment-Free and Cross-Modal Methods

报告人:崔学峰 山东大学计算机科学与技术学院 教授

报告时间:2019年12月21日 9:30-10:30

报告地点:JC1011

报告摘要:

Proteins function in living organisms as enzymes, antibodies, sensors, and transporters, among myriad other roles. Understanding protein functions has great implications for the study of biological and medical sciences. Finding remote homologous proteins, with conserved structure similarities but limited sequence similarities, is an indispensable step towards understanding protein functions.

Here, three novel methods are presented for finding remote homologous proteins with different goals: (a) the PROtein STructure Alignment (PROSTA) methods that automatically determine and align homologous structures of protein pockets and interaction interfaces; (b) the ContactLib method that scans tens of thousands of protein structures for homologous structures in seconds; (c) the CMsearch method that simultaneously explore the sequence space and the structure space to perform cross-modal search for homologous proteins. Our methods do not only improve the accuracy of finding homologous proteins, but also improve the accuracy of predicting protein structures. Moreover, case studies where our method discovers, for the first time, structural similarities between pairs of functionally related protein-DNA complexes are presented。

3. 报告题目:Cancer Subtype Analysis based on Multi-Omics Data

报告人:郑春厚 安徽大学计算机科学与技术学院 教授

报告时间:2019年12月21日 10:30-11:30

报告地点:JC1011

报告摘要:

Cancer is one of the main diseases threatening the safety of human life. With the development of high-throughput sequencing technology, a large amount of multi-omics bio-molecular data has been generated, which brings opportunities to the research on the mechanism and therapy of cancer. A series of computational methods have been proposed to make effective use of the data. Among them, the discovery of cancer subtypes has become one of the research hotspots in oncology and bioinformatics. Dividing cancer patients into different subtypes can provide basis and guidance for precision medicine and personalized medicine, so as to improve the treatment effect, as well as provide assistance for cancer mechanism analysis and drug target research and development. This talk will give out our research work about cancer subtype analysis based on Multi-Omics Data, including Scluster, ndmaSNF (network diffusion model assisted SNF) and RWCE (Random Walk based Cluster Ensemble).
