AI for Art & Design - TFUG India Summit

This talk showcases how to use TensorFlow Lite models on mobile devices to create artistic designs. There is a brief overview of how AI can be used to assist and inspire the artists and designers in their creative space. You will also learn about the open-source computer vision and deep learning tools, and use cases of AI for art and design. This talk is for you whether you are an artist or designer who would like to learn more about AI/ML; or an engineer and anyone who is interested in creating art & design with AI, in particular with mobile apps.

1. AI for Art & Design with Lite Margaret Maynard-Reid, Sept 4 2020 #TFUGIndiaSummit @margaretmz
2. #TFUGIndiaSummit | @margaretmz | #TFLite Topics • Computer vision tasks • Generative art & design • Datasets 2 AI for Art & Design TensorFlow Lite Samples & tutorials • Samples & tutorials • Community • Tools & resources • What is TFLite? • How to make apps
3. Computer Vision Tasks Complexity Image classification (single-label) Classify an image to a class Examples Painting style or artist Van Gogh Image classification (multi-label) Classify an image to multiple classes Examples Movie poster genre action, sci-fi Feature extraction Extracting latent features of an image with CNN models Examples Visual search find similar fashion Object detection Identify one or multiple objects within an image and their locations with bounding boxes. detect UI elements Segmentation Classify whether each pixel of the image belongs to a certain class segment UI elements Generative models (GANs) Two or more models trained simultaneously Examples - Generate new images - Super res - Image-to-image 3
4. Generative Art & Design AI for Art & Design with TFLite
5. #TFUGIndiaSummit | @margaretmz | #TFLite Deep Dream 2015 5
6. Use CNN neural networks Content image + style image = styled image Content Style Generated Neural Style Transfer: 50 Shades of Miaw (link) A few more samples of generated images… Style Transfer 2015
7. #TFUGIndiaSummit | @margaretmz | #TFLite Generative Adversarial Networks 2014 What are GANs? Generative Adversarial Networks (GANs) have at least two network models which compete against each other ... 7
8. #TFUGIndiaSummit | @margaretmz | #TFLite GANs variations GANs are fun but difficult to train! • 2014 Ian Goodfellow’s original GAN’s paper • 2015 DCGAN (Deep Convolutional GAN) (paper) • 2014 cGAN (Conditional GAN) - Generate images conditioned on a class (paper) • 2016 Pix2Pix – paired image to image translation (paper) • 2017 CycleGAN – unpaired Image to image translation • 2018 StyleGAN – Generate images with some control on image characteristics (paper) • Many other GAN variations… 8
9. #TFUGIndiaSummit | @margaretmz | #TFLite • Training datasets must be paired • A type of conditional GAN Link to TensorFlow tutorial Pix2Pix 2016 9
10. #TFUGIndiaSummit | @margaretmz | #TFLite CycleGAN 2017 • Training datasets are unpaired • Horses <--> zebras • Summer <--> winter • Photos to paintings (Monet, Van Gogh etc.) Link to TensorFlow tutorial 10
11. #TFUGIndiaSummit | @margaretmz | #TFLite BigGAN 2018 Large scale GAN that generates high fidelity class-conditional images. Link to paper | TF Hub biggan512, biggan-256, biggan-128 11
12. #TFUGIndiaSummit | @margaretmz | #TFLite Control the styles of the generated images • Pose • Face shape • Age • Gender • Hair color 4x4 --> 1024x1024 8GPUs trained for 1 week Current examples: faces, bedrooms and cats Link to video StyleGAN 2018 12

16. TensorFlow Lite AI for Art & Design with TFLite
17. #TFUGIndiaSummit | @margaretmz | #TFLite What is TensorFlow Lite? A framework with a set of tools for deploying ML to mobile & embedded: • A converter • An interpreter • Ops / kernels • Interface to hardware accelerations: ◦ NN AIP ◦ Edge TPu • A bunch of other tools... 17
18. #TFUGIndiaSummit | @margaretmz | #TFLite Why on device? 18 It’s all about that camera!
19. #TFUGIndiaSummit | @margaretmz | #TFLite How to make a TensorFlow Lite app? • ML model: ◦ Train / find a model ◦ Convert to .tflite format ◦ Run inference in Python ◦ Benchmark (optional) ◦ Add model metadata • Build Android app ◦ UI navigation ◦ Input image: gallery or camera ◦ Run model inference ◦ Display result in UI 19
20. #TFUGIndiaSummit | @margaretmz | #TFLite What is an ML model? • A complex mathematical function • A representation of learnings from training data 20
21. #TFUGIndiaSummit | @margaretmz | #TFLite How to get an ML model? • Train your own • Transfer learning • Download from TensorFlow Hub • Use ML Kit 21
