Naive Bayes classifier in 50 lines - UMBC ebiquity

The Naive Bayes classifier is one of the most versatile machine learning algorithms that I have seen around during my meager experience as a graduate student, and I wanted to do a toy implementation for fun. At its core, the implementation is reduced to a form of counting, and the entire Python module, including a test harness took only 50 lines of code. I haven’t really evaluated the performance,

Monte - machine learning in Python

Monte (python) is a Python framework for building gradient based learning machines, like neural networks, conditional random fields, logistic regression, etc. Monte contains modules (that hold parameters, a cost-function and a gradient-function) and trainers (that can adapt a module's parameters by minimizing its cost-function on training data). Modules are usually composed of other modules, which

最尤推定、MAP推定、ベイズ推定 - 人工知能に関する断創録

1.2.5 曲線フィッティング再訪 1.2.6 ベイズ曲線フィッティングのところを実装してみます。前回は、最小二乗法で曲線フィッティングをしたけど、ベイズ的な方法で解こうって話のようです。この2つの節では、最尤推定最大事後確率（MAP）推定ベイズ推定という3つのパラメータ推定方法が曲線フィッティングという具体例で説明されてます。他の教科書では抽象的に定式化されていて違いがよくわからなかったけど、この章では曲線フィッティングという具体例に基づいて説明されているのでわかりやすいと感じました。最尤推定まず、最尤推定のプログラムです。実は、最尤推定で対数尤度（1.62）を最大化することは、最小二乗法の二乗和誤差関数E(w)の最小化と等価なのでwの求め方は最小二乗法（2010/3/27）とまったく同じです。最尤推定では、目標値tの予測分布を求めるためもう1個予測分布の精度パラメータ（
