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

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

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 tensorflow cython numpy Add the repo with particular opencv version conda config --add channels conda-forge Install opencv conda install opencv Run setup python3 setup.py build_ext --inplace Download weight file for the model and place it in bin/ Run ./flow --imgdir sample_img/ --model cfg/yolo.cfg --load bin/yolo.weights

Transparent Latent GAN
Pretrained network model Transparent latent GAN Python3 CUDA toolkit cuDNN Jupyter Anaconda Ubuntu VM 2 CPU,6 GB RAM, K80 GPU with 12GB RAM,50 GB Disk
27
Howto Git clone Prepare anaconda conda create -n NAME python=3.6 source activate NAME cd transparent_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 (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
28
Hardware Notes Google Compute Engine preemptive K80 ~$0.20 CAD / Hour
I used vanilla Ubuntu 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
29
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
30
Path of least resistance
Anaconda cuDNN 7 CUDA toolkit 9 Ubuntu 16.04 nVIDIA GPU > 6 GB RAM
31
You can do this now

Limits Too good to be true?
34
CSI zoom and enhance

CSI Zoom and Enhance for real

We got him – URL 937
40
We look up the registered owner
Cops go out Shoot the guy CSI Calgary saves the day Case closed
41
Let’s run the same image through a different model
43
Zoom and Enhance
44
What?
45
Wait … what?
46
Side by side
49
Different model will CONVINCINGLY lead you to a different conclusion
50
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
51
NN has learned to make convincing fakes
Those fakes may be rooted in reality or they may be purely hallucinated into existence The degree to which it’s rooted in reality depends on the data it’s been exposed to during training Garbage in – elaborate bullshit out
52
In the news: Woody Herrelson Look alike
The image of the suspect, taken from the surveillance footage, was extremely pixelated and turned up no results in Facial ID system Investigators used high-quality images of Harrelson found on Google and submitted them in place of the suspect's more pixelated image. The result ended in a match. An unidentified man was booked and charged for petty larceny.
53
So when is the AI apocolypse coming?
54
Sells well but the world doesn’t need more of it
Risk of AI Create AI that succeeds at producing output that is apparently super-intelligent, super accurate, and super trustworthy When in reality the output is elaborately disguised bullshit Sells well but the world doesn’t need more of it
