Let's introduce ourselves!

Hi !
I create this topic to introduce ourselves. I start :slight_smile: :

I am 28 and work as a Financial Risk Manager in France. I have got a degree in finance but did not know much about Bayesian statistics in college.
I am very interested in Bayesian Statistics because it seems more straightforward to me. My goal in the next coming months is to be able to rethink what I do from a Bayesian perspective.
On a daily basis I model Portfolios to compute Value at Risks, volatilities, (Ex-Ante) Tracking-Errorsā€¦

I will do my best to bring my knowledge on these subjects !

Hi @CamilleMo :wink:

I am Junpeng Lao, a Post-doc in psychology, currently in University of Fribourg, Switzerland. So if you are interested in open science and how to deal with replication crisis using Bayesian Statistics, please drop me a message.

I learned Python and Bayesian Statistics by learning PyMC3. As part of my learning process, I ported the Lee and Wagenmakersā€™ Bayesian Cognitive Modeling book into PyMC3 (repository here). Currently, I am part of pymc_devs and contribute to the code wherever I can :wink:

I also help set up the pymc discourse community, so if you have any suggestion, please let me know!

Thanks @junpenglao for building this community ! I think this is a good initiative to help people getting started with Bayesian analysis in general and PyMC3 in particular. :+1:

Hi!

Iā€™m Maxim, a bachelor student from Moscow State University, I study Economics there. In spare time I learn Approximate Bayesian Inference and itā€™s applications. Currently I have an internship at Yandex as Data Scientist. I also love active sports especially roller-skating.

Hi,

Iā€™m Thomas, PyMC3 developer and Director of Data Science at Quantopian. I did my PhD on computational psychiatry at Brown where I got exposed to Bayesian statistics and PyMC2. At Quantopian we use PyMC3 to evaluate trading algorithms and track uncertainty over time.

Hi,

Iā€™m Jon, I work as a data scientist for a subscription/ppv video service in Scandinavia (viaplay.com). Iā€™m from a design/product development background so compared to most of you guys Iā€™m very much a noob. My work mainly consists of regression modeling, and divergent transitions are my mortal enemy =).

Hi, Iā€™m Austin. Iā€™m a PyMC3 developer (mostly documentation and examples) and Principal Data Scientist at Monetate. I dropped out of a PhD program in pure math at the University of Illinois and now I build machine learning products for marketers. I love PyMC3 because it has been, at least for me, the shortest path between math idea and Bayesian inference. I hate hyperparameter optimization, and I am fascinated by the ability of Bayesian nonparametric models to choose what are normally thought of as hyperparameters.

Hi, Iā€™m Jonathan. Iā€™m a quant/trader. I recently left WorldQuant, and will soon be starting a new position at a prop firm in Austin, TX. I really like the intuitiveness of probabilistic programming and the simplicity of PyMC3.

Hi, Iā€™m RĆ©mi. Iā€™m currently finishing a postdoc in theoretical physics and am transitioning to the data science world. I fell in love with Bayesian statistics when I was looking for something else than bootstrap (which made no logical sense to me) to compute uncertainties in regression. Then I stumbled upon the stochastic block model in network analysis and became obsessed. Now I spend my days trying to understand how machine learningā€™s weird stuff (regularization, anyone?) can be understood in a Bayesian framework. Iā€™d like to become a regular contributor of PyMC3 once Iā€™ve landed a job in data science!

Hey! Iā€™m Colin. Iā€™m a PyMC3 developer (main contributions have been in the Hamiltonian methods, but also improving testing/CI processes) and software engineer in Cambridge, MA. In my past I was a pure mathematician who studied geometric measure theory. I love working on pymc3 because of the pleasant interaction between theory and application ā€“ I am super excited about how the library is catching up with state of the art algorithms, and how friendly the community is!

Hi Iā€™m Peadar Coyle, I work as a Data Scientist for ElevateDirect. Iā€™ve a Masters in Mathematics from the University of Luxembourg (and it was just shortly after that period when I met Thomas Wiecki).

Iā€™m a contributor to PyMC3 (mostly documentation, examples and some model evaluation stuff) - I use it professionally for things like survival analysis of customers.

Hello! Iā€™m Bhargav, I am finishing up my undergrad thesis in INRIA, France on Machine Learning stuff. Iā€™m a Google Summer of Code student for the summer, working on RMHMC. I love the python data science community, and like to travel around to different PyCons and PyDatas in Europe to talk about the awesome python data science stack.

Hi

Iā€™m Osvaldo. I am a researcher at The National Scientific and Technical Research Council (Argentina), where I work in the field of structural bioinformatics. I am trying to, increasingly, devote most of my work-time to probabilistic modeling of biomacromolecular structures (using PyMC3, of course!).

I also contribute code to PyMC3 whenever I can, and I have helped to make the code from the puppy book and Statistical rethinking available in Python/PymC3. Learning Bayesian statistics was a game changer for me, suddenly many things began to make sense! I love Bayesian statistics and PyMC3 and I want to share my love with others, now I am preparing material for an introductory Bayesian course, that will be freely available (but probably in Spanish). I am helping to host the first Latin American PyData, and one of the keynote speakers will be Chris Fonnesbeck!

I also love other things like music and musical instruments (specially bass and guitar), drinking beers, movies, bikingā€¦ sometimes I think I will need more or less 5 lifetimes to do all that I want and then I realize sampling is really fast with PyMC3 and I feel hope again!

Hi, Iā€™m Ben
Iā€™m a lecturer in a small psychology department in Scotland, UK (lab website). I guess Iā€™m a domain specialist in that Iā€™m a cognitive scientist, but Iā€™ve also been Bayesian for a while and done a fair bit of modelling of some sort or another.

Iā€™ve done a bit of work on Bayesian models of visual attention. More recently, Iā€™ve switched over to looking at ā€œhigher-levelā€ decision making. Specifically Iā€™m interested in risky and delayed choice tasks, basically decision making.

Iā€™ve got a long history with Matlab, and I recently published a Toolbox which does hierarchical inference for people with delay discounting data. Iā€™ve got many plans to extend this any make it super awesome - but itā€™s become clear that thatā€™s not possible in Matlab/JAGS. So Iā€™m trying to port this over to Python/PyMC3. At the moment, itā€™s in stealth mode, but I might open up the GitHub repo and welcome some co-development in exchange for co-authorship :slight_smile:

While Iā€™m a Bayesian, and I understand the simpler sampling algorithms, Iā€™m not a computer scientist nor a statistician. So itā€™s unlikely that I can contribute much to core PyMC3, but Iā€™m open to contributing some examples once Iā€™m up to speed.

Hi,

Iā€™m a researcher at Yale University. I study hearing, quantitative genetics, and computational psychiatry, whatever that is. You can read more about me here if you like.

Iā€™m more of an enthusiastic consumer than contributor to PyMC3. My first paper using PyMC3 just got accepted and should be online soon!

Hey Ben,

This sounds fascinating! I might be interested in helping port this sort of thing to PyMC3ā€¦do you have any relevant references I could read to ground myself in the basic psychology, but moreso the relevant mathematical models (I am a mathematician after all).

Welcome @sammosummo. Good to see a fellow Computational Psychiatrist here :).

Great stuff. Have sent a PM to follow this up

Hi, Iā€™m a student and Iā€™m trying to learn more about Bayesian statistic.
