Tesco Clubcard: #customerloyalty is dead! It’s all about membership! #clubcard #tesco #loyalty #data #datamining #algorithms
(First things first, four months since my last post…. apologies, just a lot of things going on.) The “rona” has done a lot of things to retail, it’s also done an awful lot of things to the economy. The UK furlough scheme reduced incomes and made customers very very very price sensitive. And today is…

The National Trust and the Travelling Salesperson – #TSP #Data #NationalTrust @NationalTrustNI #R #RLang
I’ve not had to change much of my routine when it comes to self isolation, I work from home anyways. Saying that with all my speaking engagements cancelled (and rightly so) my brain needed something else to do….. The Travelling Salesperson problem has fascinated me for years but I’ve never had the time to really…

Machine Learning Hands On 2nd edition now available. #machinelearning #ai #java #kafka #clojure #weka #dl4j #spark #r
Towards the end of February the author copies of the second edition of my book, Machine Learning: Hands-on for developers and technical professionals landed on my desk. I’m very happy with the way it’s turned out. I’ve spend the last few months resting, asides from the day job at Digitalis.io – the plan was to…

Simple Linear Regression in 2 minutes. #machinelearning #linearregression #java
With certain data Simple Linear Regression wins and while the rest of the ML/AI world push tools that are far larger scope than needed for most, sometimes our best tools are hidden in plain sight. Apache Commons Math, old, kinda forgotten but kinda cool, well Simple Linear Regression is hiding in there and is easy…

Like BigData tools you won’t need AI 99% of the time . #bigdata #data #machinelearning #ai #hadoop #spark #kafka
The Prologue. Recently I’ve been very curious, I know that alone makes people in tech really nervous. I was curious to find out the first mentions of BigData and Hadoop in this blog, April 2012 and the previous year I’d been doing a lot of reading on cloud technologies and moreover data, my thirty year…

How to run R scripts from Clojure – #clojure #r #datascience #data #java
An interesting conversation came up during a tea break in London meeting this week. How do run R scripts from within Clojure? One was simple, the other (mine) was far more complicated (see the “More Complicated Ways” section below). So here’s me busking my way through the simple way. Run it from the command line…

Refining the Coefficient. Iterative Improvements In Learning. #data #machinelearning #linearregression
Refinement is an iterative process, sometimes quick and sometimes slow. If you’ve followed the last few blog posts on score prediction (if not you can catch up here) I’ve run the data once and rolled with the prediction, basically, “that’s good enough for this”. The kettle is on, tea = thinking time This morning I…

The Next Five Years of Machine Learning. #machinelearning #data #bigdata @brianmacnamee @digitalcircle
Last night I attended the Royal Irish Academy lecture “Show me your data, and I’ll tell you who you are” at Ulster University’s Magee Campus. It was an interesting lecture by Dr Brian MacNamee, one that sidestepped any technicalities and aimed for a general audience. It was a very good, informative and entertaining lecture. One…

The NiTechrank Retrospective. #opendata #nijobs #clojure #opensource #data
The @nitechrank was a simple index to report the changes in programming jobs in Northern Ireland. It wasn’t anything scientific and for all my hailing of the automating of all things possible, meaningless and trivial…. well it was me editing the tweets every morning, with a fresh cup of tea, half asleep and in my…

Are Artificial Intelligence Frameworks the new Web Frameworks? #AI #MachineLearning #Data #ArtificialIntelligence
I spent most of Sunday morning working on some updates and a couple of corrections on my book, Machine Learning: Hands on for Developers and Technical Professionals. The comments and feedback all centred around a common theme. Validating the Muse. Interestingly a lot of the comments centred around decision trees which at least proves they…
