Regularization for Machine Learning

These contents were taugh in summer school RegML 2016 by Lorenzo Rosasco and this GUI in python was submitted as part of final exam.

All the coded and tested functions are in RegML.py and GUIs code structure is in RegML_GUIv2.1.py

Github Page

PyPi -project

Installation

pip install regml

Opening GUI:

import regml
regml.GUI()

Methods

• Regularized Least Squares -RLS Referance
• Nu-Method Referance
• Iterative Landweber Method Referance
• Singular Value Decomposition Reference
• Trunctated SVD Referance 1 Referance 2
• Spectral cut-off

Kernal Learning

(Linear, Polynomial, Gaussian)

• Linear
• Polynomial
• Gaussian (RBF)

K-Fold Cross Validation

GUI

Using local files

---

Use these files

1. RegML.py
2. RegML_GUIv2.1.py
3. Getting_Started_Demo.ipynb

Requirments

Following libraries are required to use all the functions in RegML library

1. Python(=2.7)
2. Numpy(>=1.10.4) Numpy
3. Matplotlib(>=0.98) Matplotlib
4. Scipy(>=0.12) Optional -(If you need to import .mat data files) Scipy

Tested with following version

GUI is tested on followwing version of libraries

• Python 2.7, 3.7
• Numpy 1.10.4
• Matplotlib 1.15.1
• Scipy 0.17.0

Getting starting with GUI

Windows------------------------

After lauching python, go to directory containing RegML.py and RegML_GUIv2.1.py files and run following command on python shell

>> run RegML_GUIv2.1.py

If you are using Spyder or ipython qt, browes to directory, open RegML_GUIv2.1.py file and run it

Ubuntu/Linux-------------------

Open terminal, cd to directory contaning all the files and execute following command

$ python RegML_GUIv2.1.py

if you have both python 2 and python 3

$ python2 RegML_GUIv2.1.py

If you are using Spyder or ipython qt, browes to directory, open RegML_GUIv2.1.py file and run it

Getting Started with DEMO

Getting_Started_Demo is a IPython -Notebook, which can be open in Ipython-Notebook or Jupyter
