  1. 2.

    AI: The Next Big Thing™ • Communication was the Internet’s

    killer app – web apps storing data to DBs ruled • My view… AI will be the next killer app – Faster & cheaper GPU hardware – Lots of R&D around machine learning – Cool applications • Self-driving cars • Good speech recognition • Automating repetitive manual tasks • “The secret sauce”
  2. 3.

    Getting into AI • …probably a good idea • Applying

    AI != researching AI • Modern AI frameworks – Torch (Facebook) – Theano (academy) – TensorFlow (Google)
  3. 4.

    TensorFlow (TF) • Great AI framework built in Google –

    Easy for developers and researchers – Production-ready • MapReduce – White paper only – Hadoop became the standard • TF open sourced to became the standard • Model marketplace
  4. 5.

    TF Overview • DataFlow programming language • describe a graph

    of interacting operations that run entirely outside Python – Graph – Session
  5. 7.

    Performance • CPU (C++ implementation – pretty efficient) • GPU

    – even faster! • JIT compiler – Speed things up by adding a single line of code – Experimental • XLA compiler – Ahead-of time compilation – Run on embedded devices (phones, IoT)
  6. 9.

    Deployment • Google Cloud & AWS offer VMs with GPUs

    • FloydHub – Heroku for AI – https://www.floydhub.com/
