Next-generation technologies: developers to users and developers to developers
Theme:Artificial Intelligence
Machine learning technology is helping make the lives of millions worldwide simpler, safer, more enjoyable, and overall better. Developers are at the heart of this change in how we use technology. However, there are some fields where this technology makes more impact than others, and my passion lies in, and I think it makes most sense to apply this technology in healthcare, education, and development! In my keynote, I'll be showcasing and demoing a few of my projects in these fields. Particularly, I'd like to show off the flexibility of machine learning, and how developers can not only apply it to create better applications, but to make their own lives easier as well.

Deep Learning for Mobile devices
Theme:Artificial Intelligence
Over the last few years, convolutional neural networks (CNN) have risen in popularity, especially in the area of computer vision. Many mobile applications running on smartphones and wearable devices would potentially benefit from the new opportunities enabled by deep learning techniques. However, CNNs are by nature computationally and memory intensive, making them challenging to deploy on a mobile device. We explain how to practically bring the power of convolutional neural networks and deep learning to memory and power-constrained devices like smartphones. We’ll illustrate the value of these concepts with real-time demos as well as case studies from Google, Microsoft, Facebook and more. You will walk away with various strategies to circumvent obstacles and build mobile-friendly shallow CNN archit...
