This the second part of Reinforcement Learning (Q-learning). If you would like to understand the RL, Q-learning, and key terms please read Part 1.
In this part, we will implement a simple example of Q learning using the R programming language from scratch. It is expected from you to understand the basics of R programming and complete the reading of Part 1 of this article.
We are coding the algorithms using the R base package…Continue

Have you heard about AI learning to play computer games on their own and giving tough competitions to expert Human gamers?
A very popular example being Deepmind whose AlphaGo program defeated the South Korean Go world champion in 2016. Other than this there are other AI agents developed with the intent of playing Atari games like…Continue

Quite often, non-technical executives have difficulties understanding what programming, on a very fundamental level, is all about. Because of that knowledge-gap, they tend to hire and overburden experienced data professionals with tasks which they are hopelessly overqualified for. Such as, for example, doing ad-hoc SQL queries on CRM data: "You're the go-to-guy for all things data, and we need the results for the board meeting tomorrow." That's a quite humbling and frustrating…Continue

Nowadays, most data scientists use either Python or R as their main programming language. That was also my case until I met Julia earlier this year. Julia promises performance comparable to statically typed compiled languages (like C) while keeping the rapid development features of interpreted languages (like Python, R or Matlab). This performance is achieved by just-in-time (JIT) compilation. Instead of interpreting code, Julia compiles code in runtime. While JIT compilation has…Continue

One can seriously argue about what programming language is the best for data analysis, but there is one universal metric that can define your choice: speed of calculations. Therefore, the word "best" in the title means the languages that lead to most performant applications. If most performant program can also be written in an easy-to-use, easy-to-learn, dynamically-typed…

The following advice is built from my experience working as a data scientist on a variety of projects across different data & engineering teams. Many data scientists (myself included) do not come from a computer science or software development background, so may not have formal training or good habits in code writing. These tips should help data scientists work collaboratively to write good code and build models in a way that will be easier to…Continue

This is a tutorial to show how to implement dashboards in R, using the new "flexdashboard" library package.
this new library leverages these libraries and allows us to create some stunning dashboards, using interactive graphs and text. What I loved the most, was the “storyboard” feature that allows me to present content in Tableau-style frames. Please note that for this you need to create RMarkdown (.Rmd) files and insert the code using the…Continue

In order to prevent my programs from freezing up while running long calculations, I generally run the calculations on separate threads. In Java, this process can be accomplished by separating the GUI from processing. In the code below, a thread for an instance of MyProcessing would be invoked using start(): e.g. “(new MyProcessing()).start();” would run indefinitely until T is made null. T can be made null by calling stop() or by directly making T null. Often when the GUI is closing, I…Continue

Last Sunday at Trivadis Tech Event, I talked about R for Hackers. It was the first session slot on Sunday morning, it was a crazy, nerdy topic, and yet there were, like, 30 people attending! An emphatic thank you to everyone who came!
R a crazy, nerdy topic, - why that, you'll be asking? What's so nerdy about using R?
Well, it was about R. But it was neither an introduction ("how to get things done quickly with R"), nor was it even about data science. True, you…

Probably like most people, I tend to recognize data as a stream of values. Notice that I use the term values rather than numbers although in practice I guess that values are usually numerical. A data-logger gathering one type of data would result in data all of a particular type. Perhaps the concept of “big data” surrounds this preconception of data of type except that there are much larger amounts. Consider an element of value in symbolic terms, which I present below: there is an index such…Continue
