Verifiable Credentials : Decentralized Credential Flows

Microsoft has launched ION hosting (beta) on Bitcoin mainnet, and new verifiable credentials service (private preview) on Azure Active Directory (Azure AD). In this post, I will summarize what is verifiable credentials and how it works.
This style of identity and credentials are very much like our physical world. I hope this future credential backed by decentralized technology will mitigate the impedance mismatch between the real world and the digital world.

Mathematical Introduction to SVM and Kernel Methods

In this post, I describe how SVM works to make you understand strengths / weaknesses, the parameter meanings, so on and so forth in the practical use.
These ideas behind SVM are based on mathematics (statistics). However, for building your intuitions, I’ll try to explain with a lot of samples and visualizations. This post will also be helpful for you to learn kernel methods.
