Time to take stock of what is going on in the #TechIndustry, how #GenAI is changing the jobs, and how to integrate it in your career.

Here is a super dense, and hopefully actionable, episode with the great Jordan Thibodeau -- make sure to give his SVIC Podcast a listen!
🎙️ What does it take to grow in tech? Jordan Thibodeau shares lessons from years inside top tech cultures with @alex-andorra.bsky.social

✅ Bayesian thinking as a practical advantage

✅ AI amplifies skill, not replaces it

✅ Networking & sharing knowledge matter

This one is a very practical one, with the great Maurizio Filippone -- all about the intersection of #DeepLearning , #GaussianProcesses and why combining them is so powerful. Enjoy!
Bayesian deep learning helps ML models understand their uncertainty

In this episode @alex-andorra.bsky.social talks with Maurizio Filippone about Gaussian Processes, scalable inference, MCMC, and Bayesian deep learning at scale

How to run #BART and #TreeModels fast in #Python -- new episode is out, with @gstechschulte.bsky.social !
🤔How do you keep Bayesian rigor when the data’s too big to behave?

@gstechschulte.bsky.social joins @alex-andorra.bsky.social on Learning Bayesian Statistics to talk BART and how they’re bridging classic stats with modern, large-scale systems.

Really recommend this one, about how to blend #CausalInference and #DeepLearning in practice, with ChiRho and Pyro!
🧪 Causal inference is about understanding why things happen, not just what

@alex-andorra.bsky.social talks with Sam Witty about ChiRho & how probabilistic programming is reshaping interventions, counterfactuals, and the future of causal reasoning

This was a super fun one, geeking out on LLMs, deep neural nets and optimization with Maximilian Balandat, from Meta
What if your optimization algorithm could explain its uncertainty as clearly as its results?” 🤔

🚨 MCMC or INLA?

🤯 MCMC = slow sampling.
⚡ INLA = fast, smart approximations. No chains, no waiting.

🎙️ On LBS, @alex-andorra.bsky.social talks with Haavard Rue & Janet Van Niekerk about how INLA works, when to use it, and why it’s a game-changer.

New episode is out! A really fascinating one with Robert Ness, about his new #CausalAI book, which actually kickstarted a whole new learning path for me
Robert and I are actually working on an educational project you're gonna love... Follow @learnbayesstats.bsky.social for the upcoming announcement!
Models need more than pattern-matching.
They need causal understanding.

In this episode, Robert Ness joins @alex-andorra.bsky.social to explore:

⚡ Why models need real-world biases
🧠 How causal rep learning is reshaping AI
🤖 What it takes to add causality to DL

🚨 Tired of MCMC cooking your CPU for hours?

@alex-andorra.bsky.social chats with Haavard Rue & Janet van Niekerk about INLA, a fast, deterministic game-changer for inference at scale.

✅ Handles huge + complex models
✅ Works with non-Gaussian likelihoods

Came across this 𝗲𝘅𝗰𝗲𝗹𝗹𝗲𝗻𝘁 𝗲𝘅𝗮𝗺𝗽𝗹𝗲 using the 𝗛𝗼𝗿𝘀𝗲𝘀𝗵𝗼𝗲 𝗣𝗿𝗶𝗼𝗿 — a powerful Bayesian tool for #SparseRegression — via the @pymc.io & Bambi ecosystem, so wanted to share it with you folks!

A big thanks to @aloctavodia.bsky.social & @tomicapretto.bsky.social for their great and continued work on this 🙏
🧲 Got 50 predictors, but only 5 that matter?

Try the Horseshoe Prior — a Bayesian approach to sparse regression that shrinks noise, not signal.

Built with Bambi + @pymc.io

Even when they converge, they might be wrong in ways you won’t see—unless you look differently

We covered some of the most practical and under-discussed tools in #Bayesian econometrics:
🔷 #DynamicRegression
🔷 #StateSpaceModels
🔷 Predictively consistent priors
🔷 Bayesian R²
🔷 Whether AI could help us elicit better priors
Some people think R² doesn’t belong in Bayesian models
