ofxBayes

Introduction

ofxBayes is openFrameworks addon for Bayesian statistics. Now this is a baby project. Currently, you can

• Add your own hypothesis and probability as map<int, int>
• Write your own likelihood function by giving lambda function.

for detail take a look at codes below.

Dependency

currently none.

Example

example-basic

Simple Monty-hall problem. Three steps required.

1. Make prior probability 2. Write likelihood function 3. Update your guess!

``[cpp]

//Hypothesis and data _map[0] = 0.f; _map[1] = 0.f; _map[2] = 0.f;

//initialization ofxBayesHist hist(_map); hist.initialize(); hist.disp("Prior probability");

//Likelihood function int choise = 0; hist.likelihoodFunc = [=](int data, int hypo) {

if (hypo == data) return 0.f; else { if (hypo == choise) return 0.5f; else return 1.f; } };

//update posterior prob. hist.update(1); hist.disp("Posterior probability"); ``
