State of PPL: How are Bayesian methods used in industry?

I recently put together a survey of over 100 data scientists and analysts. There’ll be a report coming super soon, but before then I wanted to share the infographic. We’ll go into more detail in the report. If you’d like to get access to the report you should sign up  here 70 percent of data scientists… Continue reading State of PPL: How are Bayesian methods used in industry?

Think you need to learn Bayesian Analysis? Read this first

Bayesian Analysis the good parts One of the questions I’m often asked is what’s so powerful about Bayesian analysis? I speak regularly to analysts, who’ve heard of some of the powerful aspects of it, but haven’t heard enough to emotionally invest time in learning it. I’ve thought about this on and off for a few… Continue reading Think you need to learn Bayesian Analysis? Read this first

3 reasons to learn Bayesian Statistics in the new year

What is Bayesian Statistics Bayesian Statistics (or Probabilistic Programming) take a more effective and deep approach to perform analysis of any given data and situation. A/B testing is one of the hottest topics on the internet nowadays. In this testing, you simply consider two different groups, A and B, to analyze the performance of both… Continue reading 3 reasons to learn Bayesian Statistics in the new year

New Screencast: How do I build a Logistic Regression model the Bayesian way?

One question that is often asked by those who know Machine Learning to me is how do I build a Bayesian Logistic Regression model? If you know how to build a logistic regression model in sklearn or a standard machine learning library it’s quite easy to learn how to do the Bayesian version. In this screencast… Continue reading New Screencast: How do I build a Logistic Regression model the Bayesian way?

What is BFMI (Bayesian Fraction of Missing Information)?

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)?

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
