Math for Data Science in One Picture: What do you REALLY need to study?

In my last blog post, I covered the statistics you need to know for data science. But of course, stats isn't the only math related knowledge you need. Rather than offer my own biased opinion about the importance of this subject vs. that one, I performed a meta analysis of popular opinion to see what data scientists and educators are saying (see…

Web Scraping with a Headless Browser: A Puppeteer Tutorial

Web development has moved at a tremendous pace in the last decade with a lot of frameworks coming in for both backend and frontend development. Websites have become smarter and so have the underlying frameworks used in developing them. All these advancements in web development have led to the development of the browsers themselves too.  Most of the browsers are now available with a “headless” version where a user can interact with a website without any UI. You…

Optimal Binning for Scoring Modeling (R Package)

What is Binning?

Binning is the term used in scoring modeling for what is also known in Machine Learning as Discretization, the process of transforming a continuous characteristic into a finite number of intervals (the bins), which allows for a better understanding of its distribution and its relationship with a binary variable. The bins generated by the this process will eventually become the attributes of a…

It Is Never Too Late To Learn!

The article by Stefanie Glen in the November 30 DSC Newsletter  is spot on!  I am a 77-year old Data Scientist, and I have done my best work since I “retired” in 2009.  Since then, I published 3 books on Data Science topics with Academic Press, and a 4th book is in press at Cambridge University Press.  I began teaching Data Science at the University of California at Irvine in 2012.  All of my students are international (in an international program at UCI), and almost all of them…

Why Event Stream Processing Is Leading the New Big Data Era

Big Data is probably one of the most misused words of the last decade. It was widely promoted, discussed, and spread around by business managers, technical experts, and experienced academics. Slogans like “Data is the new oil” were widely accepted as unquestionable truth.

These beliefs pushed  technologies forward. Its stack, formerly developed by Yahoo! and now owned by the Apache Software Foundation, was recognized as “The” Big Data…

Deep Analytics: Risk Management with AI

We first provide a mini-tutorial on  Adjoint Algorithmic Differentiation (AAD) (also known as back-propagation in machine learning). We then illustrate how  neural networks may be used to compute dynamic values and risks of trading books with applications to risk management of derivatives,  valuation adjustments (XVA), counterpart credit risk, FRTB and SIMM margin valuation adjustments (MVA). We also describe new techniques to substantially improve deep learning on simulated data, and…

Data Cleaning and Wrangling With R

Originally posted by Michael Grogan.

One of the big issues when it comes to working with data in any context is the issue of data cleaning and merging of datasets, since it is often the case that you will find yourself having to collate data across multiple files, and will need to rely on R to carry out functions that you would normally carry out using commands like VLOOKUP in Excel.
