Leave No Valuable Data Behind: the Crazy Ideas and the Business:
With the mission “leave no valuable data behind”, we developed techniques for knowledge fusion to guarantee the correctness of the knowledge. This talk starts with describing a few crazy ideas we have tested. The first, known as “Knowledge Vault”, used 15 extractors to automatically extract knowledge from 1B+ Webpages, obtaining 3B+ distinct (subject, predicate, object) knowledge triples and predicting well-calibrated probabilities for extracted triples. The second, known as “Knowledge-Based Trust”, estimated the trustworthiness of 119M webpages and 5.6M websites based on the correctness of their factual information. We then present how we bring the ideas to business in filling the gap between the knowledge at existing knowledge bases and the knowledge in the world.

Margaret Mitchell, Senior Research Scientist, Google’s Research & Machine Intelligence group
Margaret Mitchell is the Senior Research Scientist in Google’s Research & Machine Intelligence group, working on advancing artificial intelligence towards positive goals. She works on vision-language and grounded language generation, focusing on how to help computers communicate based on what they can process. Her work combines computer vision, natural language processing, social media, many statistical methods, and insights from cognitive science. Before Google, She was the Researcher at Microsoft Research, and a founding member of their “Cognition” group. Her work focused on advancing artificial intelligence, with specific focus on generating language from visual inputs. Before MSR, she was a postdoctoral researcher at The Johns Hopkins University Center of Excellence, where she mainly focused on semantic role labeling and sentiment analysis using graphical models, working under Benjamin Van Durme.
Margaret received her PhD in Computer Science from the University of Aberdeen, with supervision from Kees van Deemter and Ehud Reiter, and external supervision from the University of Edinburgh (with Ellen Bard) and Oregon Health & Science University (OHSU) (with Brian Roark and Richard Sproat). She worked on referring expression generation from statistical and mathematical perspectives as well as a cognitive science perspective, and also worked on prototyping assistive/augmentative technology that people with language generation difficulties can use. Her thesis work was on generating natural, human-like reference to visible, everyday objects. She spent a good chunk of 2008 getting a Master’s in Computational Linguistics at the University of Washington, studying under Emily Bender and Fei Xia. Simultaneously (2005 – 2012), She worked on and off at the Center for Spoken Language Understanding, part of OHSU, in Portland, Oregon. Her title changed with time (research assistant/associate/visiting scholar), but throughout, she worked under Brian Roark on technology that leverages syntactic and phonetic characteristics to aid those with neurological disorders.
She continues to balance my time between language generation, applications for clinical domains, and core AI research.
Serena Yeung, PhD Student, Stanford
Serena is a Ph.D. student in the Stanford Vision Lab, advised by Prof. Fei-Fei Li. Her research interests are in computer vision, machine learning, and deep learning. She is particularly interested in the areas of video understanding, human action recognition, and healthcare applications. She interned at Facebook AI Research in Summer 2016.
Before starting her Ph.D., she received a B.S. in Electrical Engineering in 2010, and an M.S. in Electrical Engineering in 2013, both from Stanford. She also worked as a software engineer at Rockmelt (acquired by Yahoo) from 2009-2011.
Tianqi Chen, Computer Science PhD Student, University of Washington
Tianqi holds a bachelor’s degree in Computer Science from Shanghai Jiao Tong University, where he was a member of ACM Class, now part of Zhiyuan College in SJTU. He did his master’s degree at Changhai Jiao Tong University in China on Apex Data and Knowledge Management before joining the University of Washington as a PhD. He has had several prestigious internships and has been a visiting scholar including: Google on the Brain Team, at Graphlab authoring the boosted tree and neural net toolkit, at Microsoft Research Asia in the Machine Learning Group, and the Digital Enterprise Institute in Galway Ireland. What really excites Tianqi is what processes and goals can be enabled when we bring advanced learning techniques and systems together. He pushes the envelope on deep learning, knowledge transfer and lifelong learning. His PhD is supported by a Google PhD Fellowship.

Beating Perils of Non-convexity:Guaranteed Training of Neural Networks using Tensor Methods:
Neural networks have revolutionized performance across multiple domains such as computer vision and speech recognition. However, training a neural network is a highly non-convex problem and the conventional stochastic gradient descent can get stuck in spurious local optima. We propose a computationally efficient method for training neural networks that also has guaranteed risk bounds. It is based on tensor decomposition which is guaranteed to converge to the globally optimal solution under mild conditions. We explain how this framework can be leveraged to train feedforward and recurrent neural networks.
