Introduction/purpose

The Machine Learning focus group will span over PWG, hardware and computing activities that aim at developing and delivering machine learning techniques for STAR. As computational related, the pages starts under the S&C Drupal

Our main goal and is to see analysis techniques using ML to be presented and shared, discussed and improved as well as lesson learn and findings from analyzers passed from one to another for a mutually beneficial outcome.  ML techniques are especially hard to optimize and your shared experience would be an asset to others. Similarly, we hope to see the development of GANs and other techniques that may propel the Physics capabilities of STAR (speed of GANs over standard simulator would be a huge step forward for STAR).

First ML@STAR Workshop - March 7th 2019

ML Tools and Tutorials :

Tools - 

1. Scikit-Learn - http://scikit-learn.org/stable/ 
   Easiest to start and play around with - comes standard and integrates with your existing python installation
2. Keras - https://keras.io/
   State of the art libraries and functions with predefined networks and relatively easy to implement examples
3. Tensorflow - https://www.tensorflow.org/
   Google product and most often used as the backend for keras libraries to run on. You can also have tensorflow specific code as you follow up from the example
4. Theano - http://deeplearning.net/software/theano/
   Also a backend for keras. main difference w/ tensorflow are in how images are defined (x, y, pixel-w) vs (pixel-w, x, y). its being less used now
5. Cuda toolkit - https://developer.nvidia.com/cuda-toolkit
   A bit of an advanced toolkit for more serious developers. fully contained set of libraries in c++ code, takes advantage of gpu optimization
6. PyTorch - https://pytorch.org/
   front end with native python setup similar to Keras
7. Mxnet - https://mxnet.apache.org/
   more of a backend alternative to tensorflow

Tutorials -

1. Building your first network : https://machinelearningmastery.com/tutorial-first-neural-network-python-keras/ Im very fond of this website! it is one of the best in explaining the details and proving hands on examples for you to learn and play. 
2. Learning from data - https://work.caltech.edu/telecourse 
3. Stanford classes about CNNs and vision http://cs231n.stanford.edu/
4. Another class about vision and object recognition  https://www.di.ens.fr/willow/teaching/recvis17/
5. CMU course on deep learning http://deeplearning.cs.cmu.edu/
