I recently gave a talk to the excellent research team at Signal Media. And got asked the question I didn’t want to be asked. It was what is the BFMI in PyMC3? The way I largely think of it is, in a practical level – which is – if the BFMI metric is below the… Continue reading What is BFMI (Bayesian Fraction of Missing Information)?

I help organisations understand, assess and execute on emerging opportunities in data science and machine learning. I've helped organisations from startups to larger organisations unlock value from their data in verticals such as Supply Chain Management, Advertising and Financial Services. I am happiest at the intersection of product, data science and engineering. My work has exposed me to working with sales people, legal (GDPR), risk and various other functions or cross-functional teams.If you're looking for a data scientist for some advisory work or technical due diligence, if you have a project in mind or are looking for me to do some writing or speaking, feel free to get in touch peadarcoyle@googlemail.com
Why would I ever NEED Bayesian Statistics?
Probabilistic Programming versus Machine Learning In the past ten years, we’ve seen an explosion in Machine Learning applications, these applications have been particularly successful in search, e-commerce, advertising, social media and other verticals. These applications have been particularly focused on predictive accuracy and often involve large amounts of data — sometimes in the region of terabytes — in fact this… Continue reading Why would I ever NEED Bayesian Statistics?

How do I visualise the results of a Bayesian Model: Rugby models in Arviz
I’ve been recently playing around with ‘arviz’. For those of you who don’t know Arviz is a library for exploratory analysis Bayesian Models. I’ve got a Bayesian model built – or someone has built one for me, how do I explore it? How do I plot it? This is the fundamental question that Arviz answers.… Continue reading How do I visualise the results of a Bayesian Model: Rugby models in Arviz
Coding is hard
Today after over a decade of programming, I was reminded that programming is hard. I was committing a fix to PyMC3 (but it could have been any project, and I definitely make those mistakes professionally), and Thomas was good enough to point out ‘break-point committed’. JD Long shared his own war stories. The lesson I… Continue reading Coding is hard
I’m an Analyst and the software engineers made fun of my code!
I’m seeing a very fuzzy line between where technical business analysts end & IT teams begin. Y’all know of good articles/books on managing responsibilities when coding analysts on the biz side interface with IT dev teams? Seems tricky. #rstats #pydata #python — JD Long (@CMastication) October 19, 2018 My friend JD Long, has been a… Continue reading I’m an Analyst and the software engineers made fun of my code!
How to use AWS Lambda to build a tweetbot
Inspired by Vicki I decided to build a Tweetbot – the code is available here. You can follow the tweetbot online – the architecture that Vicki proposed is basically what I did, only I made a few changes in the code. Time taken It’s worth pointing out first that it took me approximately 32 hours of… Continue reading How to use AWS Lambda to build a tweetbot
What is a Message Broker for?
I’ve been working in tech for a few years now, and that’s included writing a lot of code. One thing I never got my head around was what is a message broker? I’ve definitely seen them in architecture meetings, and heard people speak of ‘RabbitMQ’ and ‘Redis’ but I don’t really know what they’re for.… Continue reading What is a Message Broker for?
Adding value as Data Scientists
I’ve been thinking and discussing with various people lately – ‘career path for data science’. Someone said to me recently: Go become a research scientist and specialise in specific machine learning models say NLP at a specific company such as Google, Amazon, etc. Become a data scientist at a startup or growth company and accept… Continue reading Adding value as Data Scientists
Interview with a Data Scientist – Vicky Boykis
It gives me great pleasure to interview Vicki Boykis – we’ve chatted a lot on Twitter over the past few years and her blog/ side projects have been inspiring for my own. Vicki is a Data Scientist and Engineer who tweets awesome stuff. She’s well worth following. Her twitter bio – Born: Jewish in Russia. Raised:… Continue reading Interview with a Data Scientist – Vicky Boykis
