If you don't want to host your Ghost blog on a server, you may want to try Ghost Static Generator and push the content to your GitHub repo. There is one Python-based Ghost content crawler call buster. However, the tool is no longer maintained by the author for more than 5 years.

Feature scaling stands for transforming variable values into a certain standard range. Feature scaling can quite important for certain machine learning algorithms, such as gradient descent, support vector machine. This post is about introducing several feature scaling techniques.

GitHub remains one of the most reliable repository website for code, but we can also utilize its storage capability to host images for our website. The easiest way is simply to upload/push image files to your GitHub repo and get the link from the web. But beyond manual upload, we always prefer elegant ways.

From K-means we know that:

• K-means forces clusters to be spherical
• In K-means clustering every point can only belong to one cluster

In mathematics, the Hessian matrix or Hessian is a square matrix of second-order partial derivatives of a scalar-valued function, or scalar field. It describes the local curvature of a function of many variables. Hessian Matrices are often used in optimization problems within Newton-Raphson's method.

K-means clustering is a type of unsupervised learning, which is used for unlabeled data (i.e., data without defined categories or groups). The goal of this algorithm is to find groups in the data, with the number of groups represented by the variable K (defined manually as an input).

Matrix factorization is a class of algorithms used for recommendation systems in machine learning. Matrix factorization algorithms work by decomposing dimensionality. Commonly known matrix factorization algorithms are SVD and PCA.

This post is going to illustrate how to sync a fork of a repository to keep it up-to-date with the upstream repository.

We use .gitignore file to untrack certain folder and/or files to the remote repository. However sometimes you have some files already pushed to your remote repository. Now you want to only keep them locally, so here is how to remove them from the remote repository.
