Gaussian Process
What is a Gaussian Process?A GP is simply a multivariate Gauss distribution. The idea is very simple; we have a multivariate Gauss distribution which includes both previous measurements(or train set) and targets(test set). Either previous measurement or target, I will call them dimensions. They are some dimensions in the Gaussian Process. Since the multivariate Guassian…

Bayesian Deep Learning
Definitions Epistemic uncertainty:Uncertainty due to model itself, the model doesn’t represent the data completely because we have lack of information (obviously we have a finite set of data).Aleatoric uncertainty:Uncertainty inside the data itself. I think of it as measurement error in sensors.Heteroscedastic noise:The noise is not independent of the input features. For example, in Hadron…

Markov Chain Monte Carlo Methods
Some notes for myself… Just points to remember, I skip the overview and note the details that makes me grasp the concepts, usually why questions. Notice they are mostly my understanding from the lectures, and not intended to be a reference; I just type my understanding for future reference for myself. What is ergodicity in…

Variational Inference
Some notes for myself… Just points to remember, I skip the overview and note the details that makes me grasp the concepts, usually why questions. Can we always find an equation to analytically minimize a convex function?No. Not every convex function has an analytical solution for finding their maximum/minimum. An example would be Bayesian Logistic…

GABA Dabba Do!
GABA and its benefits GammaAminobutyric acid, or γaminobutyric acid, it is one of most important neurotransmitters in mammalian central nervous system. But what is a neurotransmitter. This cool term is not about electronics or radios. Neurotransmitters are messenger molecules between neuron cells. They are much slower than signal that has been conducted inside of the neuron.…
