Celebrating 6k+ Stack overflow

It has been a while since I joined Stack Overflow. As a programmer, I would like to acknowledge the creators and all contributors to the website. It has been an awesome resource for developers and other fields of interest. Stack Overflow is a question-and-answer site for professional and enthusiast programmers. It is a privately-held website, the flagship site of the Stack Exchange...

Latent Dirichlet Allocation (LDA) and Topic ModelLing in Python

petamind

Topic modelling is a type of statistical modelling for discovering the abstract “topics” that occur in a collection of documents. Latent Dirichlet Allocation (LDA) is an example of a topic model and is used to classify text in a document to a particular topic. It builds a topic per document model and words per topic model, modelled as Dirichlet distributions. Here, we are...

K-Means vs K-Nearest neighbours quick note

petamind

These are completely different methods in machine learning. The fact that they both have the letter K in their name is a coincidence. K-means is a clustering algorithm that tries to partition a set of points into K sets (clusters) such that the points in each cluster tend to be near each other. It is unsupervised because the points have no external classification. The typical k-means...

Lasso vs Ridge vs Elastic Net – Machine learning

How to Setup SSH Tunneling in Mac OS (or Ubuntu)

petamind

When working with Jupyter notebooks on AWS, I want to interact with it directly in my browsers. In order to do so, we may need to create an SSH tunnel from our laptop to the remote server. If you are using a Macbook, you can easily do so using the default Terminal application available in the Mac OS. Yes, we do not have to install any other application for doing so, as we do in Windows. If you...
