Artificial Intelligence and Geopolitics

 — 

I'm beginning to write about the intersection of artificial intelligence and geopolitics.


Deriving Mean-Field Variational Bayes

 — 

A detailed derivation of Mean-Field Variational Bayes, its connection to Expectation-Maximization, and its implicit motivation for the "black-box variational inference" methods born in recent years.


Deriving Expectation-Maximization

 — 

Deriving the expectation-maximization algorithm, and the beginnings of its application to LDA. Once finished, its intimate connection to variational inference is apparent.


Additional Strategies for Confronting the Partition Function

 — 

Stochastic maximum likelihood, contrastive divergence, negative contrastive estimation and negative sampling for improving or avoiding the computation of the gradient of the log-partition function. (Oof, that's a mouthful.)


A Thorough Introduction to Boltzmann Machines

 — 

A pedantic walk through Boltzmann machines, with focus on the computational thorn-in-side of the partition function.


From Gaussian Algebra to Gaussian Processes, Part 2

 — 

Introducing the RBF kernel, and motivating its ubiquitous use in Gaussian processes.


From Gaussian Algebra to Gaussian Processes, Part 1

 — 

A thorough, straightforward, un-intimidating introduction to Gaussian processes in NumPy.


A Practical Guide to the Open-Source ML "Master's"

 — 

Motivation, logistics and strategic insight re: designing the Open-Source "Master's" for yourself.


Joining ASAPP

 — 

I'm joining ASAPP as a Machine Learning Engineer.


My Next Role

 — 

Beginning the search for an impossibly awesome next role.
