Variational Inference
Published:
1.Latent variable models and EM algorithm
We want to model a high dimension random vector $\boldsymbol{x}$, which can often be described by only a few latent factors $\boldsymbol{z}$. LVM take a two-step generation scheme:
Basic Normalizing Flow
Published:
1.Change of variables formula
Normalizing Flows (NF) can model flexible distributions for data sampling and density estimation. The idea is based on change of variables formula, applying a series of transformations on a simple distribution to approximate a complex distribution.
Covergence cross mapping
Published:
1.Background
Convergent Cross Mapping (CCM) is a method for establishing causality from long time series data (\(\geq 25\) observations). The method was first proposed in 1990 by Sugihara et al and revisited in 2012.
Double Machine Learning
Published:
This blog post is some reading notes of the paper Double/Debiased Machine Learning for Treatment and Structural Parameters by Victor Chernozhukov et al.
Some notes about KL divergence

Learning the difference DAG between structural equation models
Published:
The paper “Direct Learning with Guarantees of the Difference DAG Between Structural Equation Models” by Asish Ghoshal, Kevin Bello and Jean Honorio studies the problem of directly estimating the structural difference between two structural equation models (SEMs) with the same topological ordering.
