This repository contains notebooks that illistrate different machine learning algorithms using embedPy.

1. Neural networks (NN notebook)
2. Dimensionality Reduction
3. K-nearest Neighbours
4. Feature Engineering (NN notebook)
5. Decision Trees
6. Random Forests

If you have Docker installed you can create a directory called q and place your kc.lic (or k4.lic) and l64.zip files into a q directory and run:

    docker run --rm -it -v `pwd`/q:/tmp/q -p 8888:8888 kxsys/ml_notebook_examples

Now point your browser at http://localhost:8888/tree/notebooks

N.B. build instructions for the image are available

These are the steps that are required to run the notebooks:

1. Install Q (version 3.5 or higher/64-bit)

   • make sure q is on the path
   • set QHOME
   • also see https://code.kx.com/q/tutorials/install/

2. Install Anaconda-Python(version 3.5 or higher)

   • see https://conda.io/docs/user-guide/install/index.html

Steps 3 and 4 are only required to run Neural Network Notebooks

3. Install Cuda (version 9.0)

   • see https://developer.nvidia.com/cuda-90-download-archive

4. Install tensorflow
