1. Challenges of building AI-powered chatbots that yield business value

Erdem Özcan, Head of Research @ Automat

Chatbots are at the intersection of messaging and artificial intelligence. Combining these two trends to build solutions that yield real business value is way more challenging than simply plugging together messaging platforms with natural language understanding APIs. In this talk, Erdem will share some of these challenges and the lessons they have learned during Automat's journey.

2. Highlights from the NIPS conference

Nicolas Chapados, Chief Science Officer @ Element AI

NIPS (Neural Information Processing Systems) is the flagship conference in the areas of learning algorithms and neural computation. Nicolas will present some of the most interesting new research results and insights that surfaced during the most recent edition of this conference.

3. Lightning Community Announcements

4. Conversations: Recent Breakthroughs

2016 was an exciting year for Machine Learning. Let’s gather in smaller groups, unconference-style, and together talk about some of the exciting results that have recently come to the fore. Discussion leaders will each introduce a topic and facilitate a conversation around the techniques and the promising directions they opened.

• Libratus (https://arxiv.org/abs/1701.01724) made history by defeating four of the world’s best professional poker players in a 20-day poker competition at Rivers Casino in Pittsburgh.

• AlphaGo (https://www.theatlantic.com/technology/archive/2016/03/the-invisible-opponent/475611/) beat Lee Sedol, a Go world champion, 4-1 last March.

• Wavenets (https://www.youtube.com/watch?v=CqFIVCD1WWo) generate speech which mimics human voice and sounds more natural than the best existing Text-to-Speech systems.

• Image Super-Resolution through Deep Learning (https://github.com/david-gpu/srez) turns images into higher-resolution versions of themselves with plausible sharp features.

• The phased LSTM network (https://arxiv.org/abs/1610.09513) adds a time gate to achieve faster convergence than a regular long short-term memory (LSTM) network on tasks which require learning of long sequences.

• LipNet (https://www.technologyreview.com/s/602949/ai-has-beaten-humans-at-lip-reading/) was able to identify 93% percent of words correctly from clips of people reading three-second sentences. Human lip-reading volunteers asked to perform the same tasks identified just 52%.

• Artistic Style Transfer for Videos (https://www.youtube.com/watch?v=Uxax5EKg0zA) builds on style transfer for images: given an input video and a reference image, it creates a video that imitates the style of the reference image with the content of the input video.

• Deep Q-learning (https://www.youtube.com/watch?v=V1eYniJ0Rnk) plays Atari games and improves itself to a superhuman level.

• StackGAN (https://www.youtube.com/watch?v=rAbhypxs1qQ) synthesizes high resolution photo-realistic images from text descriptions.
