Outline

• We went to Google IO!
• Cool stuff (for later)
• Javascript and Deep Learning
• Javascript and TensorFlow

Google IO

End of the Duplex Announcement

Google IO

Spotted in the audience

Other Cool Stuff

May cover these soon

• TensorFlow lite ~ small-TF
• ML-Kit ~ Firebase machine learning
• TFX ~ TensorFlow framework...
• • ... for training and serving ML models
• Swift ~ "Coming soon" language

Some visibility...

Who knew? Google has been updating their site..

Javascript Deep Learning

• Some history...
• Javascript development is more of a bazaar...

Convnet.js

(actual contributor in 2014)

TensorFlow Playground

Written 'ad-hoc'

Meta-Learning Demo

Uses jsNet

Distill

Nice CNN interpretability write-up

Javascript TensorFlow

• deeplearning.js : Open Source on GitHub
• Includes GPU processing!
• • ... (mis-)using WebGL
• See it up close

TensorFlow.js

Actual announcement (and demos)

Code example

( Boring )

• Via main project page
• • (use link to code at top of the page)

Code example

Exciting!

• Example project
• Interesting code to look at
• ... wait for it ...
• Actual DEMO

Use existing models

Import from Keras !

# Python
import tensorflowjs as tfjs
def train(...):
    model = keras.models.Sequential()   # for example
    #...
    model.fit(...)
    tfjs.converters.save_keras_model(model, tfjs_target_dir)  
    
# JS
import * as tf from '@tensorflow/tfjs';
const model = await tf.loadModel('https://foo.bar/tfjs_artifacts/model.json');
const example = tf.fromPixels(webcamElement);  // for example
const prediction = model.predict(example);

Browser Benchmark

Not same as native, but not bad

Node.js Deep Learning

• Javascript isn't only for the browser
• Node.js support announced at Google IO
• Still "Experimental" ...

Server Stack

Server Benchmark

Already on a par with Python

Deep Learning
MeetUp Group

• MeetUp.com / TensorFlow-and-Deep-Learning-Singapore
• Next Meeting :
• • TBA in June : hosted at Google
• Typical Contents :
• • Talk for people starting out
  • Something from the bleeding-edge
  • Lightning Talks

BONUS !

• Now FREE from Google via Kaggle (aka Colab) :
• • 12hrs-at-a-time of K-80 GPU
  • Google Colab Tips and Tricks

( Don't use for Mining )

Deep Learning : Jump-Start Workshop

• Dates + Cost : End-June, S$600
• • Full day (week-end)
  • Play with real models
  • Get inspired!
  • Pick-a-Project to do at home
  • 1-on-1 support online
