Expected Value of MLE estimate over standard deviation and expected deviation

A slecture by ECE student Zhenpeng Zhao

Partly based on the ECE662 Spring 2014 lecture material of Prof. Mireille Boutin.




1. Motivation

  • Most likely converge as number of number of training sample increase.
  • Simpler than alternate methods such as Bayesian technique.



2. Motivation

  • Statistical Density Theory Context
    • Given c classes + some knowledge about features $ x \in \mathbb{R}^n $ (or some other space)
    • Given training data, $ x_j\sim\rho(x)=\sum\limits_{i=1}^n\rho(x|w_i) Prob(w_i) $, unknown class $ w_{ij} $ for $ x_j $ is know, \forall{j}=1,...,N</math> (N hopefully large enough)
