Here is a talk I gave at the **PyData** meetup in Montreal: [Introduction to Probabilistic Programming with PyMC3](https://www.patreon.com/posts/introduction-to-27501591)

Topics covered:  
1 - Introduction to concepts of Bayesian modelling/probabilistic programming  
2 - Introduction to PyMC3  
3 - How to write your own custom likelihood function  
4 - How to use GaussianRandomWalk to model time-changing latent variables
