Speaker: Dr. Yimin YANG, Senior Director, Protiviti Inc.  Abstract:

Entropy is a natural natural functional that in some sense measures the complexity of a hypersurface.

Starting with an introduction to blockchain, this talk will explain the ideas behind Bitcoin and several other cryptocurrencies. As this industry is in the trough, blockchain technology is getting ready to leap. We will talk about ICO, STO, stablecoins and their recent developments.

We first recall some techniques of scalar curvature flow on Sn developed in my previous paper joint with Professor Xingwang Xu (Invent. Math. 2012). Next, we extend such a flow approach to prove a perturbation result of the fractional Nirenberg problem, i.e.

Deep learning has aroused extensive attention due to its great empirical success. The efficiency of the block coordinate descent (BCD) methods has been recently demonstrated in deep neural network (DNN) training.

Non-convex optimization is widely involved in many machine learning problems, and it usually implicates a two-stage algorithm: a refined initialization followed by a local gradient search.
