ML in JS
Machine Learning in JavaScript
- What is it?
- What can it do?
- How does it work?
- Should we use it?
TensorFlow
- Run pre-trained models
- MobileNet
- PoseNet
- coco-ssd
- speech-commands
- ...or you own...
- Train new models
.js
MobileNet
Demo
Why?
- Always bet on JS!
- A big step out of the data science lab
- ML with optional cloud
How?
- Uses WebGL to speed up all of the computation
But...
Doesn't training take months of compute-time on specialised hardware?

OUR EXPERIENCE
The Good
It works! It's still in use and manages to achieve > 95% accuracy
The Bad
TensorFlow.js has rough edges -
- Memory-management
- Cross-device compatibility
The Ugly
Reliable training data is hard to come by!
FIN
- ML is becoming ever more accessible
- Collecting training data is still hard
- Device support is limited
