Data Mining project in Python

Hi,

I need help with a project which have two sections. Most of the first section is complete, need help with PCA (Principle Component Analysis) on featured data set and then train output data form PCA using following machine learning techniques:

Decision Tree
SVM
Nueral Network

At this point i have features applied on data (min, max, mean, standard deviation and root mean square). Now i need help with applying PCA and then train data on mentioned machine learning.

Must have knowledge of:
1. Python development
2. Data Mining

This is urgent and needs to be done in max 3 days

Thanks
