Hyperbolic graphs induced by weighted iterated function systems

报告人：孔诗磊（德国比勒菲尔德大学）报告地点：工商楼200-9报告时间：12月9日上午10点半—11点半摘要：For an iterated function system (IFS) $\{S_j\}_{j=1}^N$ of contractive similitudes on $\mathbb{R}^d$, there is a well-known graph structure (augmented tree) X, which is (Gromov-)hyperbolic under the open set condition or some other circumstances. In this talk, we study the hyperboli...

Hyperbolic Graph and IFS

报告人：王向阳教授（中山大学）报告地点：工商楼200-9报告时间：12月9日上午9点半—10点半摘要：For a contractive iterated function system (IFS), it is known that there is a natural hyperbolic graph structure (augmented tree) on the symbolic space of the IFS that reflects the relationship among neighboring cells, and its hyperbolic boundary with the Gromov metric is H\{o}lder equivalent to the attractor...

多模态神经影像融合与智能分析处理

报告人：张俊松（厦门大学信息学院人工智能系）时间：2020年12月11日上午9:30-11:30地点：玉泉工商楼200-9摘要：脑是宇宙间最为复杂的系统之一，成人的脑中有约1000亿个神经元，单个神经元通常与其它神经元有成千上万个“突触”连接节点，形成拥有百万亿级连接的极其复杂的脑神经网络。人类个体的行为、认知功能之所以与众不同，一个原因就是大脑神经网络形态及其连接方式的差异和持续改变。因此，结合先进的神经影像成像工具、前...
