Nov 21, 2019 Introducing the Next Generation of On-Device Vision Models: MobileNetV3 and MobileNetEdgeTPU
Posted by Andrew Howard, Software Engineer and Suyog Gupta, Silicon Engineer, Google Research On-device machine learning (ML) is an essential component in enabling privacy-preserving, always-available and responsive intelligence. This need to bring on-device machine learning to compute and power-limited devices has spurred the development of algorithmically-efficient neural network models and hardware capable of performing billions of math operations per second, while consuming only a few milliwatts of power.
Nov 21, 2019 SPICE: Self-Supervised Pitch Estimation
Posted by Marco Tagliasacchi, Research Scientist, Google Research A sound’s pitch is a qualitative measure of its frequency, where a sound with a high pitch is higher in frequency than one of low pitch. Through tracking relative differences in pitch, our auditory system is able to recognize audio features, such as a song’s melody.
Nov 21, 2019 New Solutions for Quantum Gravity with TensorFlow
Posted by Thomas Fischbacher, Researcher in Compression, Google Research, Zürich Recent strides in machine learning (ML) research have led to the development of tools useful for research problems well beyond the realm for which they were designed. The value of these tools when applied to topics ranging from teaching robots how to throw to predicting the olfactory properties of molecules is now beginning to be realized.
Nov 21, 2019 RecSim: A Configurable Simulation Platform for Recommender Systems
Posted by Martin Mladenov, Research Scientist and Chih-wei Hsu, Software Engineer, Google Research Significant advances in machine learning, speech recognition, and language technologies are rapidly transforming the way in which recommender systems engage with users. As a result, collaborative interactive recommenders (CIRs) — recommender systems that engage in a deliberate sequence of interactions with a user to best meet that user's needs — have emerged as a tangible goal for online services.
Nov 21, 2019 New Insights into Human Mobility with Privacy Preserving Aggregation
Posted by Adam Sadilek, Software Engineer and Xerxes Dotiwalla, Product Manager, Google Research Understanding human mobility is crucial for predicting epidemics , urban and transit infrastructure planning , understanding people’s responses to conflict and natural disasters and other important domains . Formerly, the state-of-the-art in mobility data was based on cell carrier logs or location "check-ins" , and was therefore available only in limited areas — where the telecom provider is operating.
Nov 12, 2019 Highlights from the 3rd Cohort of the Google AI Residency Program
Posted by Katie Meckley, Program Manager, Google AI Residency This fall marks the successful conclusion for the third cohort of the Google AI Residency Program . Started in 2016 with 27 individuals in Mountain View, CA, the 12-month program has grown to nearly 100 residents from nine locations across the globe.
Nov 12, 2019 Quantum Supremacy Using a Programmable Superconducting Processor
Posted by John Martinis, Chief Scientist Quantum Hardware and Sergio Boixo, Chief Scientist Quantum Computing Theory, Google AI Quantum Physicists have been talking about the power of quantum computing for over 30 years, but the questions have always been: will it ever do something useful and is it worth investing in? For such large-scale endeavors it is good engineering practice to formulate decisive short-term goals that demonstrate whether the designs are going ...
