  1. AI for Beginners from a Beginner

  2. About me • AI beginner • tomas@florian.ca • IT Consulting • Complex networking • Cloud / Virtualization systems • Cyber security

  3. Demos • What got me started down this path is impressive demos that I’ve seen in the last couple of years

  4. Question • Can anybody do this with now with open source software? • Yes

  10. 2x Demo • Show • Unwrap • Howto • Questions • Navigating Limits of AI • Questions

  11. Demo #1 Object Detection

  12. Object Detection

  13. Object Detection

  14. Unwrap: Black Box ./flow --imgdirsample_img/ --model cfg/yolo.cfg --load bin/yolo.weights

  15. Neural Network ./flow --imgdirsample_img/ --model cfg/yolo.cfg --load bin/yolo.weights

  16. Neural Network Model Weights (pre-trained) ./flow --imgdirsample_img/ --model cfg/yolo.cfg --load bin/yolo.weights

  17. Darkflow Dependency Stack OpenCV TensorFlow model weights Python3 darkflow Anaconda Ubuntu 18.04 VM i7 CPU, 4 GB RAM

  18. Howto • git clone https://github.com/thtrieu/darkflow • Create conda virtual env for the project • conda create -n NAME python=3.6 • source activate NAME • Install dependencies • conda install tensorflowcythonnumpy • Add the repo with particular opencv version • condaconfig --add channels conda-forge • Install opencv • conda install opencv • Run setup • python3 setup.py build_ext --inplace • Download weight file for the model • https://drive.google.com/drive/folders/0B1tW_VtY7onidEwyQ2FtQVplWEU and place it in bin/ • Run • ./flow --imgdirsample_img/ --model cfg/yolo.cfg --load bin/yolo.weights

  19. Questions?

  20. Demo #2 Generative Adversarial Network (GAN)

  21. ThisPersonDoesNotExist.com

  22. Demo #2

  23. Unwrap: Black Box

  24. GAN Generative Adversarial Network Pre trained generator network

  25. Transparent Latent GAN Pretrained network model Transparent latent GAN Python3 CUDA toolkit cuDNN Jupyter Anaconda Ubuntu 16.04 VM 2 CPU,6 GB RAM, K80 GPU with 12GB RAM,50 GB Disk

  26. Howto • Git clone https://github.com/SummitKwan/transparent_latent_gan.git • Prepare anaconda • conda create -n NAME python=3.6 • source activate NAME • cdtransparent_latent_gan • Install dependencies • conda install pip • pip install -r requirements.txt • conda install cudatoolkit • conda install cudnn • conda install jupyter • Download pre-trained model https://www.dropbox.com/sh/y1ryg8iq1erfcsr/AAB--PO5qAapwp8ILcgxE2I6a?dl=0 (extract to same folder structure) • Run notebook • jupyter notebook • Navigate to URL shown at startup + notebooks/transparent_latent_gan/src/notebooks/tl_gan_ipywidgets_gui.ipynb • Run notebook

  27. Hardware Notes • Google Compute Engine preemptive K80 ~$0.20 CAD / Hour • I used vanilla Ubuntu 16.04 and installed Nvidia drivers on it myself • Prebuilt images but more $ per hour (not preemptive) • REMEMBER TO TURN IT OFF • Nvidia GX 1060 (6 GB RAM … more is better) $300 • Nvidia-smi

  28. Expectations • 80% of time dealing with building the stack • Poor documentation • Missing/incompatible pre-trained models • Dependency hell (much better with Anaconda) • Unhelpful error messages • 20% real AI work

  29. Path of least resistance • Anaconda • cuDNN 7 • CUDA toolkit 9 • Ubuntu 16.04 • nVIDIA GPU > 6 GB RAM

  30. You can do this now

  31. Questions

  32. LimitsToo good to be true?

  33. CSI zoom and enhance

  34. CSI Zoom and Enhance for real • https://github.com/alexjc/neural-enhance

  35. Zoom and Enhance

  36. …Again

  37. … Again

  38. We got him – URL 937

  39. We look up the registered owner • Cops go out • Shoot the guy • CSI Calgary saves the day • Case closed

  40. Let’s run the same image through a different model

  41. Zoom and Enhance

  42. What?

  43. Wait … what?

  44. Side by side

  45. Different model will CONVINCINGLY lead you to a different conclusion

  46. Which license plate was it? • Maybe URL 937 • Maybe BBL 3698 • Maybe SOMETHIN ELSE • Even though we are seeing it in front of our own eyes there is a threshold at which AI can just make stuff up and make it look like the real thing
