Excited to share that our latest work on grid spectral mixture product (GSMP) kernel has been featured in Prof. Sergios Theodoridis' latest book "Machine Learning: From the Classics to Deep Networks, Transformers and Diffusion Models"! 🎉

Catch me at #ICLR2025 ... if you want to chat about Gaussian processes, dynamical systems, Bayesian inference, or just to enjoy some coffee ☕️

Make sure to get your tickets to AABI if you are in Singapore on April 29 (just after #ICLR2025) and interested in probabilistic modeling, inference, and decision-making! Tickets (free but limited!): lu.ma/5syzr79m More info: approximateinference.org #Bayes #MachineLearning #ICLR2025 #AABI2025

These sparse Gaussian Processes have been around longer than some grad students, but still fun to code! (and today was my first time coding one...)

I already advertised for this document when I posted it on arXiv, and later when it was published. This week, with the agreement of the publisher, I uploaded the published version on arXiv. Less typos, more references and additional sections including PAC-Bayes Bernstein. arxiv.org/abs/2110.11216

This paper on sparse variational Gaussian processes is quite intriguing... I always find great enjoyment in reading Titsias's work.

Diffusion Without Tears Discussion

Excited to share our ICLR 2025 oral "Residual Deep Gaussian Processes on Manifolds"! With @vabor112.bsky.social & @arkrause.bsky.social, we introduce manifold-to-manifold GPs that can be composed together, generalising deep GPs to manifolds. Applications include wind prediction & Bayes opt! 1/n

The deadline for abstract submission of contributed papers and posters for BayesComp2025 has been extended to 28 February. Decisions by 14 March. Submit here! bayescomp2025.sg/abstract-sub... The deadline for early bird registration has been extended to March 22. Hope to see you in Singapore!

Nothing compares to the moment my newborn smiled at me. Pure, unfiltered joy and love. My heart is so full... 🥹💖

2. The SLIM-KL framework, combining quantized ADMM for privacy and communication efficiency with Distributed Successive Convex Approximation for scalable optimization. 3. Theoretical convergence guarantees and superior performance on diverse datasets, showcasing scalability and efficiency.

In this work, we addressed challenges in Gaussian process (GP) regression for multidimensional and large-scale data. Our key contributions: 1. A new GP kernel that reduces hyperparameters while maintaining strong performance, promoting sparsity for efficient optimization.

Thrilled to share that our paper has been accepted by IEEE TNNLS! This is my first journal paper as a mentor and a co-first author. I’m incredibly proud to have collaborated with @richardcsuwandi.bsky.social. Richard’s dedication made this a truly rewarding experience.

One #postdoc position is still available at the National University of Singapore (NUS) to work on sampling, high-dimensional data-assimilation, and diffusion/flow models. Applications are open until the end of January. Details: alexxthiery.github.io/jobs/2024_di...

Langevin Monte Carlo (LMC). Just tried to generate a video to visualize the process 😀

Inventors of flow matching have released a comprehensive guide going over the math & code of flow matching! Also covers variants like non-Euclidean & discrete flow matching. A PyTorch library is also released with this guide! This looks like a very good read! 🔥 arxiv: arxiv.org/abs/2412.06264

A common question nowadays: Which is better, diffusion or flow matching? 🤔 Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably.

I made a starter pack for machine learning researchers working on Bayesian optimization and Gaussian processes! It's *very* sparse ATM since the migration is still in progress. Please reply to make me aware of people - potentially yourself - who should be added to it! go.bsky.app/QYMEQ52
